Best Car Battery Chargers

If you own a car, then chances are you’ve experienced one of those dreadful moments when you turn the key in your ignition, and nothing happened! A dead battery is something no one has time to deal with and can ruin all your day’s plans. However, if you own a car battery charger, then you can avoid this inconvenience and waste of time waiting for a friend or stranger to rescue you with a jump-start.

Fortunately, there are tons of different car battery chargers today that can help you avoid such scenarios. Depending on your circumstance, you shouldn’t have a problem finding one that suits your need. And, did you know that most of today’s battery chargers can help condition your battery, improving its performance and extending its lifespan? Some even come with smart inbuilt features that allow for more efficient and safer use.

1. Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp Jump Starter | Editor’s Choice & Best Seller

Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12 Volt Jump Starter
  • 1,700 Peak Amps; 425 Cranking Amps
  • 22Ah Clore PROFORMER Battery
  • 46" Heavy-Duty #2 AWG Cables
  • Voltmeter provides charge status of onboard battery
  • DC outlet to power 12 volt accessories; DC input to recharge internal...

The JN660 by Clore is perhaps one of the best car accessory investments you’ll ever make. This jump starter primarily focuses on giving your battery a jumpstart with extended cranking power. One charge is good enough to perform several jump starts, which is a relief in the normally stressful situation of a drained out battery. So, how does this jump starter do that?

Well, it has a couple of unique features that make this possible. The first is the length of its heavy-duty leads. At 46”, the cable leads are long enough to get around a majority of vehicles. Furthermore, it has industrial-strength Hot Jaw clamps capable of making secure connections despite corrosion.

Then, there’s Clore proprietary Proformer Battery Technology that’s all about deliver max power with matching durability and density. As such, you not only get lasting and proper cranking power, but you also get a longer-than-usual service life too. Furthermore, the starter’s onboard battery comes with fully-automated recharging, which means you can leave this starter unit plugged in and ready for instant jumpstarts whenever it’s needed. This is, undoubtedly, one of the best car chargers on the market today and is a car starter most customers won’t pass up.

Pros
  • Long lasting
  • Extensive, long-lasting cranking power
  • Automatic charging
  • Isn’t hindered by corrosion
Cons
  • No light included
  • The air compressor isn’t up to par

2. STANLEY J5C09 Power Station Jump Starter: 1000 Peak/500 Instant Amps, 120 PSI Air Compressor, Battery Clamps | Best Jump-Starter | Simplicity at its Finest | Runner Up

  • Features a 120 PSI air compressor to help inflate tires with low...
  • Built-in 12V DC outlet and USB port provide portable power for...
  • Jump starter should be charged every 30 days when not in use; Charges...

The J5C09 by Stanley is, without a doubt, one of the best car starter considering that it has high-output power capable of jump-starting small to large vehicles without a problem and has several critical features that prove handy in times of emergency. Some of these features include a flashlight and a flat tire compressor. In addition to this, the J5C09 is rated to work even in cold conditions when batteries have a hard time performing.

Unlike other car jump starters that simply create jolts to get engines to turn over, the Power Station Starter is both a battery charger and jump-starter. Its trickle charger feature allows you to maintain batteries in cars that you do not use often.

The starter’s cables are 3.5ft long, which allows them to reach battery connections with ease. However, they are not so long that they’re a nuisance to store, even in their built-in storage. While the J5C09 is not as portable as the Clore Jump-n-Carry JNC660 ultra-portable jump starter, it still will not take up that much space in your car’s trunk.

To recharge the J5C09 battery, simply plug into a wall outlet. The great thing is that it has an overcharge protection safety feature. The reverse polarity warning is another safety feature on the J5C09 that proves to be handy. This feature alerts you when you have set up the connections incorrectly like when you connect the negative clamp on the positive connection.

Pros
  • Heavy for a jump starter
  • Long cables
  • Air compressor for inflating tires
  • 1,000 peak amps
Cons
  • Just one USB port
  • One-year warranty only

3. Battery Tender Plus 021-0128, 1.25 Amp Battery Charger is a Smart Charger

Battery Tender Plus is a very user-friendly option. The starter’s intuitive and straightforward design is easy-to-use, making it a car starter that anyone, even those with the least car knowledge can use.

Apart from ease of use, Tender Plus also has a ton of built-in safety features like spark protection that prevent accidents. This starter will automatically shut down when it notices that the battery has reached its capacity to keep it from overcharging. In such instances, Tender Plus automatically goes to maintenance mode, recharging the battery only when it begins to lose its charge.

Pros
  • 10-year warranty
  • Easy to use
  • Durable
Cons
  • The company’s customer service is wanting
  • Not as powerful or specialized as other options

4. NOCO Genius G3500 6V/12V 3.5 Amp Battery Charger and Maintainer | Versatile Choice

  • Works with all types of 6-volt and 12-volt lead-acid batteries,...
  • Keep your battery fully charged without worry or overcharge. Simply...
  • Use our advanced Repair Mode to reverse the damaging effects when...

The NOCO Genius 3500 can charge both 6-volt and 12-volt batteries. We’ve focused on the Genius 3500 here before, but this is starter has proven to be a natural choice for most people. According to car experts, this one of the most dependable car battery starters in the market because it’s available in a range of amperes. If you do not need 3.5 amperes, you can always go as low as 0.75 amps or as high as 26 amps. NOCO’s 15 and 26-ampere models are known to jump start completely dead cars.

The Genius 3500’s versatility is what sets this charger apart. Apart from a wide range of amperes, you can also use it on 6-volt and 12-volt batteries, as well as gel cell, wet cell, lithium ion, lead acid, and calcium batteries. Not only can this charger be used on car batteries, but it can also be used on lawn, marine, and power sports equipment.

The charger also comes with active monitoring, which lets you know how your battery is doing (health wise) and repairs damage from sulfate and discharge to optimize and lengthen battery life.

The Genius 3500 includes a user manual, a charger, clamps with integrated eyelet terminals and a 5-year warranty.

Pros
  • Intuitive design
  • Portability
  • Versatility
  • Interacts with battery
Cons
  • Repair feature only works on 12-volt batteries
  • Complex operation
  • This model cannot jump start dead batteries

5. DBPOWER 600A 18000mAh Portable Car Jump Starter (up to 6.5L Gas, 5.2L Diesel Engine) Battery Booster and Phone Charger with Smart Charging Port

  • WHAT YOU GET: DBPOWER Jump Starter DJS50, intelligent jumper clamps,...

No one likes having battery trouble and not just because jumpstarting a battery is sometimes frustrating and tedious, but also because a majority of jump-starter kits are often cumbersome things to work with! However, that is not the case with the DBPOWER 600A. This jump starter isn’t your typical jumpstarting kit. And you will notice that the moment you set your eyes on it. The DBPOWER 600A is more compact compared to other kits – it is so compact it can even fit in the glove box of your car.

Just because it is small, that doesn’t mean that it has compromised on power. This little fella packs a peak output of 600 amperes, enough amps to jump-start a 5.2-liter diesel or 6.5-liter petrol engine 20 times on one charge. And when you don’t need it to charge up your battery, which is quite often, you can use its Smart USB port to juice-up your devices – tablets, laptops, smartphones, and so forth.

Furthermore, the DBPOWER 600A is cleverly-designed to avoid things that threaten its performance like short-circuiting and overcharging. However, despite these qualities being unique, not all of them are positive. For instance, trying to jump-start your vehicle with the starter at less than 30 percent charge can prove futile. As such, you are advised to perform jump starts on a full charge. Gratefully, the DBPOWER 600A comes with a 3-year warranty that you can lean on should the worst happen.

Pros
  • Relatively-high power output
  • Compact design
  • Designed to prevent short-circuiting and overcharging
  • Can be used to charge personal electronic devices
Cons
  • Doesn’t come with adequate instructions
  • Doesn’t maintain charge well
  • Doesn’t perform well on low charge

6. BLACK+DECKER BM3B Fully Automatic 6V/12V Battery Charger/Maintainer with Cable Clamps | Best Value

BLACK+DECKER BM3B Fully Automatic 6V/12V Battery Charger/Maintainer with Cable Clamps
  • Charges and maintains 12 volt and 6 volt AGM, GEL and WET batteries
  • Easy connection to vehicle battery using battery clips and O-ring...
  • Stops charging automatically when battery is fully charged or topped...
  • Built-in circuit protection guards against overcharging, reverse...
  • Mounting bracket built-in to charger for convenient placement

The BM3B by Black & Decker is a small, ultraportable car battery charger. The thing we like about this charger is its capability to charge both 6-volt and 12-volt batteries automatically. The BM3B also comes with automatic float mode, which automatically shuts down charging once the battery is fully recharged and starts monitoring it for discharge.

The great thing about this battery charger is that it can charge almost all types of car batteries available on the market, ranging from the latest AGM batteries to the traditional lead-acid models.

The useful thing about this car battery charger is that it comes with a switch that allows users to switch between 6-volts and 12-volts easily.

Despite being a bit low-powered, having only 1.5 amperes, the BM3B by Black & Decker is still a dependable car battery charger due to its versatility and capability to charge all types of batteries on the market, and that includes 6-volt motorcycle batteries.

Pros
  • Small and compact
  • Useful LED indicators
  • It is very affordable
  • Easy to switch between 6-volt and 12-volt recharge mode
Cons
  • Only 1.5 amperes of power; Making it difficult to charge high-capacity batteries fully

7. Schumacher SEM-1562A-CA 1.5A 6V/12V Automatic Maintainer

No products found.

When it comes to matters related to power management, there are very few companies that can compete with Schumacher’s sheer gravitas. With that being said, it is worth noting that the company doesn’t actually specialize in making car battery chargers. However, they do specialize in making a variety of power management products like testing devices and power converters. Nevertheless, Schumacher is, without a doubt, a cut above the rest and is capable of not only providing some of the best car chargers but also does so at significantly lower costs compared to their competition.

While the SEM-1562A-CA is one of the least expensive car battery chargers we’ve reviewed, it is worth noting that the jump starter offers some legitimately-impressive control features. However, it isn’t the control settings that are striking but the mechanism that enables them – specifically, its microprocessor. SEM-1562A-CA’s microprocessor keeps track of the battery’s energy readings, ensuring that it doesn’t supply power with readings that could damage the battery. Gratefully, the microprocessor also enables the jump starter to charge at different levels.

It is worth noting that the Schumacher SEM-1562A-CA’s microprocessor does more than just track energy readings. The exciting thing about it is that it has one of the rarest forms of protection we’ve seen in any of the car battery chargers we have tested before. Essentially, this battery charger is capable of withstanding high temperatures compared to other chargers on the list – which is a huge deal considering that this is one of the most common dangers car battery chargers face. To top that off, the microprocessor also ensures that the charger doesn’t overcharge the battery, which means you can leave it connected the entire time. Schumacher SEM-1562A-CA’s microprocessor essentially gives it the ability to work on different charge settings.

Pros
  • Can charge two different voltages
  • This is the least-expensive charger we’ve reviewed
  • Has two different connectors
  • Has different charge settings
  • It is compact
  • Has a unique microprocessor
  • Safe to leave connected
  • One of the fastest chargers around
  • Comes with temperature protection
Cons
  • Designed to maintain
  • Only provides one amperage

8. GOOLOO 1000A Peak 20800mAh SuperSafe Car Jump Starter with USB Quick Charge 3.0 | Best Ultra-Portable Jump-Starter

  • ADVANCED PROTECTION & UPGRADED SECURE CLAMP: The GP200 has built-in...
  • PORTABLE CHARGER & LCD SCREEN: 20800mAh Capacity with Dual USB Ports....
  • WHAT’S INCLUDED: GOOLOO GP200 Jump Starter, 12V Battery Clamp, Wall...

The GP200 is our top pick when it comes to ultra-portable jump-starters considering that it packs a high-powered 1,000 amperes output into a small 6” box. What does that mean? It means that this tiny thing is powerful enough to bring large trucks back to life, but is still small enough to fit under a passenger seat or even in a glove box.

Given its compact size, you can take the GOOLOO GP200 camping or hiking to charge your electronic devices.

Since the GOOLOO GP200 packs a rechargeable lithium-ion battery, it still works even in temperatures that make your battery prone to discharging. This jump-starter can also serve as a mobile device charger and comes with two dedicated USB ports that you can use to charge up your tablets and smartphone while camping or driving.

The device’s battery is capable of jump-starting a vehicle approximately 30 times on a single charge. The GP200 has a charging indicator on its LCD screen that notifies you when it is running low on power.

However, the GOOLOO GP200 has one downside – its cables, which are only 6-inches long. It is worth noting that this is the standard length for most ultra-portable car battery charger cables. But, considering that they are too short, it can be hard to reach the battery’s connections, especially if your battery is quite huge. However, this is a minor inconvenience that’s easily outweighed by the charger’s portability and the fact that it has an LED flashlight that you can use to provide light in dark and low-light conditions.

Pros
  • Small enough to carry around
  • Comes with a built-in flashlight
  • 1,000 peak amperes
Cons
  • GOOLOO’s support is limited
  • The 6-inch cables are too short
  • The flashlight is hard to turn on

The fact that it is automatic means that it needs very little-to-no operation. All that is required of you is to plug it in and leave it alone. The MP00205A has special microprocessor-controlled programming that continually monitors the charging process, stopping it once the battery is charged. After that, it starts tracking the battery’s voltage while maintaining its maximum charge using a floating current.

There are also several other safety features apart from overcharge protection. The MP00205A has prevention measures in place to protect against short-circuiting and reverse polarity. As a result, none of the components inside the battery charger will produce sparks. The device’s Constant Pulse Current Maintenance feature prevents against excessive discharge or charge, which effectively enhances the lifespan of your battery.

Another MP00205A feature worth mentioning is the SAE system. This system offers users several quick release connection options – Alligator Clips and Ring Terminals. As ring terminals form a permanent connection with your battery, they allow you to easily connect your MP00205A via various SAE adapters if need be.

MP00205A’s design is founded on improving energy use. It’s a design that’s been certified by the UL, RoHS, CEC, and CE. The MOTORPOWER MP00205A comes with technical assistance from customer service and a one-year warranty.

Pros
  • Energy-efficient design
  • Wide range of uses
  • Comes with SAE adapters
  • Plenty of safety features
Cons
  • It has an average performance
  • The LED indicators are poorly-designed

Your Guide To Buying Car Battery Chargers

The Type

While every product that we have reviewed are presumably battery chargers for cars, some are slightly more specialized in their functions, and even though they are able to charge car batteries, their intended use is actually geared towards other tasks. In most cases, this leans more towards the way the battery-charger interacts with a battery when each reaches different levels of charging. It is important to note that not all the battery charger types are designed to charge batteries which are drained completely. Similarly, certain battery chargers have been designed for use on the older batteries which otherwise would have been on their way out.

Maintainer

This happens to be the “middle ground” in association with various battery charger types. These chargers are not able to recharge a battery that is completely drained like the standard chargers are able to. At the same time, they are also not heavily focused on restoring the cells of the battery to its former state. Rather, these battery chargers are designed to keep batteries that still contain some charge from running out completely along with providing a certain level of cell maintenance in the process. These battery chargers are usually not capable of handling battery issues that are more extreme. In addition to these factors, the individual models will often be limited to the battery type that it is able to charge.

Charger

These are standard battery charger types and is the type more commonly used unless there is a fairly particular type of circumstance. These chargers come in several varied permutations which include the majority of the battery types, the highest level of voltages and amperages. What this basically means is that, regardless of the type of battery you have in your car, there will be a standard-charger which is able to handle it. One stand out advantage about the standard chargers is the ability to charge batteries which are completely drained. In addition, these chargers are usually inexpensive when compared to their counterparts. They are also designed for a much wider range when it comes to vehicles when compared to other car battery charger types.

Restorer

This type is less common, while the charging functions in truth are just a necessity of the actual function of this product. In essence, the restorer has the ability to break-down different types of contaminant build-ups in the cells of the battery to restore the functions of the battery in order to hold electric charges. This typically takes place through a number of manipulations associated with the charging-energy which will then realign the constituents in the cells or break-down any byproducts. This car battery-charger type is typically expensive when compared to other types and only becomes necessary when you have many batteries and vehicles that need to be charged and restored regularly. If you only own a single vehicle and you do not require any other uses for these chargers, this is not a purchase regarded as worthwhile.

Voltage

The voltage types that the car battery-charger is able to produce will determine if it is appropriate for use when it comes to the battery in your vehicle. For example, the car battery charger is often used for charging batteries in other types of vehicles too. Marine crafts and trucks all use the car-battery chargers, with many that use batteries which is not a standard 12V which cars generally use.

Fortunately, there are many car-battery charges available which offer an extensive array of differing battery voltages which they are able to distribute. In fact, there are even the chargers that are able to charge low voltages of 6V and even up to the high voltages of 48V. This ultimately means that a car battery charger is able to service the vehicles which range from as small as a go-kart onto large industrial vehicles.

Safety

This forms an important part of the modern chargers used for car batteries. The latest versions feature different types of safety features that protect the batteries and the driver of the vehicle. Below are a few of the primary safety features to expect from the good-quality car battery chargers:

  • Spark-proof clamps
  • Reverse polarity alarm
  • Float Mode
  • Battery tester
  • Clamp amps

Amperage

Similar to voltages, the range is far stretching when it comes to the amperages that the different battery types require. With this in mind, similar to the different voltages that car battery chargers are able to provide, so do a lot of the car-battery chargers offer the option to distribute electricity using different amperages. In some cases, the chargers will have the ability to differentiate the amperage required by itself. On the other hand, you will need to find out what type of amperage the batteries will need and then manually set the charger to a specific amperage.

It is important to know that the different types of amperage also has an effect on how fast or slow the charger will be able to charge the batteries. It is still better to take care as many batteries have a maximum amperage-rating, and when this point has been exceeded it may become dangerous to carry on charging the battery. In these cases, you could risk damaging the charger or the battery.

Charge Phases

This feature is able to significantly improve the performance of the car-battery charger, yet it is not always necessary. The car battery chargers that have differing charge phases will be able to initially read electrical signals associated with the battery followed by decoding information in order to establish the state that the battery is actually in. These chargers then adjust their own charge setting to accommodate the battery so that it can respond to potential issues.

The more common phase type that extends further than just charging associated with car-battery charges feature several charging phases which includes the Maintenance Phase, which actually doesn’t provide batteries with restorative benefits. Instead, the Maintenance Charging stage will identify what type of amperage the battery needs, the energy amount that this battery releases when it is plugged up yet not powering, where it will continue to provide that amount without overcharging the battery.

Active Monitoring

This is a standard feature among the majority of the low-ampere chargers, and we would never suggest buying products that do not include this feature. The active monitoring provides the charger with a way to give you more information about the battery.

Lower ampere versions use this feature to establish when a battery that is unused starts to lose charge. This activates the battery in order to allow for a way to start charging, followed by switching off again to avoid overcharging as soon as it detects a full charge in the battery.

The chargers that are more comprehensive feature active monitoring that is more informative. These charger types are able to provide detailed information when it comes to the health status of the battery. They can also indicate when the battery is losing life permanently, indicate the amount of charge present in the battery, and safeguard against the common types of battery depleters which lengthens the overall lifespan of the battery.

Repair Mode

The battery charges that are included in this list also include repair modes. The main purpose of these chargers is to offer a way to extend the life of a battery and a way to recharge without having to take the battery to a mechanic. This is the reason why we regard the repair mode as an important feature when it comes to car battery chargers. This is a feature that minimizes build-up which prolongs the battery life.

Car Start

This is a feature which is not very common between the different models. It usually costs a lot more to buy the battery chargers that are able to start a car, as they take way more power. If you are looking for security in knowing you will never be left stranded when the battery in your car dies, this is a really nice feature.

AGM

AGM, which stands for absorbent glass mat, is one of the more common features in the latest car battery charger models. The older vehicles won’t benefit from this feature, but the newer cars may feature AGM batteries. This battery works in a similar way, but the chemicals in the battery are stored inside glass sheets, instead of a liquid interior. This battery is more common in the latest luxury cars and motorcycles.

When you examine your battery, you should be able to find out the type. The more common batteries include Gel (gel-filled), FLM (flooded lead acid), or AGM batteries. You need to ensure that the charger matches up to the type of battery that you have in your car.

Size

In previous years, if you needed to charge the battery in your car, it was likely that the actual charger was about the same size as the actual battery. This used to make it inconvenient to carry around a charger with you. Thanks to technology, the battery chargers for cars today are now so small that some can even fit into a purse or your hand. Yet these compact sizes present even more benefits in addition to convenience.

For example, in some situations, you might want to charge a battery for a car without the involvement of a vehicle. There are a number of circumstances whereby car batteries are used to power electronic arrays that are unrelated. In these situations. It may be a better idea to keep one of the maintenance chargers connected permanently. This is a much easier task with the compact car battery chargers, and it makes moving an array much easier.

Element Proofing

Unlike batteries which may need charging, the car battery charger is not a device that features protection from outdoor elements. The majority of these chargers is made up of circuit boards and wires along with a power transformer that changes AC input-electricity into a DC output-electricity for batteries. For this reason, if the charger is not sufficiently protected, it may fail or become damaged from exposure to such elements.

In these situations, your 2 main concerns will be dust and water. Heat may also present an issue, yet this is usually easy to handle by making sure the battery charger stays out of the sun. When it comes to dust and water, the IP rating system will determine the resistance that the car-battery charger has to these types of contaminants. This feature is a lot more important for the chargers that are used for charging the non-vehicle electronics.

Fast Charging Or Maintain Charging

You also need to determine whether you want to use the charger for fast charging or maintain-charge. If you plan to mostly maintenance charge, it is advisable to choose the chargers that charge using a lower amperage that features active-charging monitoring. If you plan to frequently charge a car battery fast, choose the type that gives more amperes, and if necessary a jump-start function.

Wall Socket Connector

You also need to ensure that the car-battery charger that you are interested in purchasing will come with a wall-socket connector that is used in your country. Every country uses its own type of wall socket connector, and the location of the manufacturer may be in another country.

Warranty

This might be an expensive purchase. If you do not plan to use the charger right away, keep in mind that problems may not arise immediately, when you are buying the product for an emergency backup. Due to this, you need to ensure the charger comes with suitable warranty coverage. The standard includes a 5-year warranty, with some models that cover even longer.

In addition to the warranty, make sure you do a bit of research about the company. Your warranty will not mean much if the company has a bad reputation when it comes to customer service. In addition, some companies will make you pay to ship back a faulty product in order to conduct the repair work. For the heavier items, a lower-end model could cost just about the same to redeem your warranty than buying a brand new product, and these processes usually take a lot longer.

How To Charge A Car Battery With A Battery Charger?

1. Setting Up and Connecting the Charger

While setting up, it is essential to ensure that the charger is off or not connected to the power source. The next step is connecting the positive terminal (red) side of the charger to the positive side of the battery, and negative (black) to the negative.

2. Charger Settings

The next step is setting the voltage (volts) and current (amps). You should consider configuring the charger at its lowest setting and allow the battery to be charged slowly. If you are in a hurry, then you can set the charger is a little bit higher for a quick charge, but you should never do this often. It is not recommended to do so that your car battery could last for long.

3. Plug in The Charger to A Power Source

The next step is to connect the charger into a power source and go about your business. A good car charger comes with a timing feature or with an automatic shut off function when charging is complete. Note: it is not wise to play the cord or move it around when it is still charging.

4. Disconnect

You should disconnect the battery when it has fully charged. To do this safely, you should first turn off the battery charger and then remove the battery from the charger’s outlets. It is wise to remove the negative clamp first and then followed by the positive clamp. Your battery is fully charged at this point, and you should be ready to go.

Safety Tip:

Anytime you want to charge your battery; it is advisable to wear protective gear. This means that you should always wear safety goggles and protective gloves. Remember, when charging your battery, there is still a risk of it exploding. For this reason, you should always follow appropriated battery safety and maintenance protocols.

Frequently Asked Questions

Can I Charge a Dead battery?

This depends on your definition of “Dead Battery”.

If you are referring to a completely flat battery due to continuous use (like forgetting to turn off your car headlights overnight), then the answer is YES! With the correct voltage and current setting, the battery can be recharged. 

On the other hand, if you are referring to car batteries that are spoiled, then, unfortunately, you cannot charge them. As a matter of fact, charging a spoiled car battery may explode or cause other damaged. The truth is that car batteries do go bad (have a predetermined lifespan). However, through proper maintenance, the battery will have an extended lifespan, but in the long run, it will die. The only solution to a dead car battery is replacing it.

Charger Vs. Jumper: – What Is the Difference?

One is used to Charge A car battery, whereas the other is used to provide the same surge of power needed to start a car.

The truth is that both do help to boost the power of a car battery; however, there is a vast difference between a charger and a jumper. All you have to note is that jumpers are primarily used as an extra battery. They are generally designed to deliver a surge of power needed to get a car started, and then the car recharges the battery.

A car battery charger, on the other hand, is as the name suggests, it charges the car battery and at the same time, can be used to start your car.

Will Leaving a Car Battery Charger On for Too Long Damage It?

Yes.

Leaving the car charger continuously connected even at its lowest amp may damage it. As such, if it is a must to leave your charger connected for long, then you should consider investing in intelligent car chargers. Such a type of charger will switch itself off when the battery is fully charged, or when you have forgotten to disconnect it from the power source.

Do Solar Car Battery Chargers Work?

Yes.

Solar powered car batteries work very well. The only limitation is that they are not as powerful as those using electrical power because they put out low amps. As such, they are the best for battery maintenance or slow battery charging. A majority of them do come with additional features such as cigarette lighter socket adapter, gorilla clamps, and others.

The best solar-powered car battery charger should put out between 500mA to 1500mA. The power will be enough to charge a car battery. They are best for those who love the outdoors, like camping, road trips, and more.

How Long with A Car Charger Take TO Charge My Battery?

This Depends On the Method and Battery charger power output.

The truth is that the time taken to charge a car battery will depend on the method used and the charger output power. For example, if you prefer using a car jump start, the car battery will take about one hour charge your car’s battery using its alternator. On the other hand, it will take longer when using a car battery charging device, and the exact time will depend on the output voltage and current.

However, on average, a car battery will table about 1 to 3 hours for it to charge fully. If you use slow charging method, then it will take more time compared to the fast charging method.

Is It Best to Charge My Car Battery Slowly or Faster?

Slow is best.

Slow charging is best as it maintains the lifespan of a battery. If you are charging your car often, then you should use 4 amps maximum. You can charge your battery fast one in a while. This way, you will not damage your battery. However, if you do it every time, then you will be destroying your battery rather than charging it. Therefore, you should always use the lowest amps while charging or maintaining your car’s battery.

At the same time, some batteries need even low amps to charge. For example, the AGM batteries need slow charging method compared to regular batteries. To identify the kind of battery you have, you should read the label. To know more about the subject, read our guide on ‘How To Charge Your Battery The Best Way.’

Do I Have to Fill Battery Water Before Charging My battery?

Yes, if your batter allows its.

You should always refill your battery with battery distilled water if it allows it. Remember, not all batteries will allow this. Many car batteries are sealed, and you cannot fill them, because they are often AGM batteries.

Conclusion

Choosing the best car battery charger can be a challenging affair. This is because there are many factors to consider to get the best charger what you need.

Hopefully, this guide has been helpful, and now you know how to find the best car charger you need. Remember, to get the best charger; it is wise first to identify what you are looking for, the features the charger is offering, the power you need, and the power the charger is delivering. With this information at hand, you will surely make the right decision in selecting the best charger on the market for you.
