Keeping your battery alive and well is really important. Fortunately, you can avoid a dead battery by having a reliable car battery charger. We’ve compiled a comprehensive guide to show you how to find the best car battery charger for your needs and budget.

Best Car Battery Charger Buying Guide

There are many different types of car battery chargers in the market and each one is different. Below is a list of items you should consider when you’re looking for top car battery chargers.

Determining The Type Of User You Are

Depending on what type of user you are, the car battery charger you choose will vary. People tend to fall under 2 categories:

  • Casual User
  • Professional User

Casual users are usually people who own at least 1 or 2 cars and live comfortably in an environment where their cars are driven daily. Most drivers fall under this category.

Professional users tend to be people who own a car shop or own a lot of cars. Professional users tend to need higher-end car battery chargers as those usually have more amps than your standard battery charger.

Do keep in mind that depending on the type of user you are, the price of the battery charger will vary as well.

Understanding Chargers Based On Battery Types

There are different types of car batteries that vehicles use:

  • Maintenance Free
  • Wet Cell (Flooded)
  • Absorbed Glass Mat (AGM)
  • Gel Cell
  • Value-Regulated Lead Acid (VRLA)

For the most part, car battery chargers with all different types of car batteries. However, in the rare cases where they don’t, it’s important to understand how each battery type is different from the other.

Additionally, keep in mind voltage. From 8V, 10V, to 12V your vehicle may have different voltage so you'll want the correct charger. For example, if you have a 12V lithium battery you'll have to get a charger that matches BOTH 12v and lithium - having the charger for just either one of those two cases is not enough.

Determine Your Battery Amp Hours

Figuring out how many amp hours your battery stores is very important. A standard full sized battery usually houses about 50 amp hours, so a 10 amp charger would be used to charge it.

It helps to know this information because it’ll tell you how long it’ll take for your car battery to fully charge. Below is a few examples of how long it’ll take to fully charge a car battery if it were completely dead:

  • 50 Amp Hours: 6 hours on a 10 amp charger
  • 100 Amp Hours: 11 hours on a 10 amp charger

If you want a formula to help you figure out how long your charge time will be, take the amp hour rating of your battery and divide it by the charger rating (amps) and then add approximately 15% as a cushion for the final calculation. Having a more powerful charger may take longer, but will save a lot of time.

Pay Attention To The Warranty

Battery charger warranty is very important. In the event that your charger dies on you, you want to feel at ease knowing that the manufacturer will either replace it or give you your money back. Each manufacturer warranty is different so it’s very important to pay attention to the fine print.

Research The Brand

A very useful tip is to do research on the brand. There are many different battery charger for cars and each brand is going to give you a different experience.

We highly recommend performing a car battery comparison between different brands. This is a great way to identify top car batteries and those that aren’t. It’s also helpful to read up on car battery charger reviews to see what other people have experienced.

Set A Budget

Lastly, another important item on your checklist is setting a budget. For a majority of buyers, the best car battery charger will not break the bank.

However, for those that are looking for something better, setting a budget is important. It’ll help you draw a solid line for what you can truly afford. This reduces overspending and make sure that what you spend your money on is actually for something you need and not something you want.

4.5/5

The NOCO Genius G3500 is truly considered to be the best battery charger for cars. This model comes in a 3.5 amp form that comes with advanced technology that delivers incredible performance. It is designed to charge twice as fast as other chargers and its compact design makes it really easy to transport.

When we discovered this charger after reading many automobile battery charger reviews, we had high expectations. Many users have used this as their main home car battery charger and we can see why. The NOCO Genius G3500 is everything you’d want from a car battery charger.

Many of the cars we owned often experienced dead batteries. The NOCO Genius G3500 is a true miracle worker because it was able to resurrect all of the batteries in our cars with no issues. We had a dead optima redtop battery and after 10 hours, it was able to bring it back to life.

One issue that we did experience was the charging indicator LED lights. Once in a while we noticed that the charger did not properly sense the battery voltage properly and only showed an amber light even when connected to a fully charged battery. Although it didn’t pose an issue, this was something that people should be mindful about.

Overall, we had a very good experience with the NOCO Genius G3500. We seriously consider this the best auto battery charger from the many we’ve used.

From our positive experience, we give the NOCO Genius G3500 4.5 stars out of 5. It was truly a Godsend when it was able to revive some of our older batteries that we assumed to be dead. This is highly recommended for both the quality and the price. If your battery fits these specs, then it's a must have.

The ALLPOWERS 18V 5W Portable Solar Car Battery Charger Bundle is a solar car battery charger that we have used with great success. It’s incredibly affordable, lightweight, and compact to keep in your car. It is able to charge 12V batteries through solar power and also generate 5 watts of energy.

We were experimenting with different car battery chargers when we stumbled upon the ALLPOWERS 18V 5W Battery Charger. We knew that this charger relies on solar power so it really caught our interest. Our main concern was trying to keep our car battery alive until we had time to buy a whole new one.

We just want to throw this out there that the ALLPOWERS 18V 5W Battery Charger is very easy to use. All you have to do is simply plug the solar charger into your lighter socket and making sure that there is plenty of sunlight to work with. After that, the ALLPOWERS 18V 5W Battery Charger will do the rest of the work for you.

One problem that we want to point out is that this solar powered car charger is not designed for 24 hour use. The problem with this car charger is that it may overheat your battery and possibly damage it. So while it is affordable and convenient, it does come with restrictions.

We recommend the ALLPOWERS 18V 5W Battery Charger to anyone that is looking for a short term solution to their car battery problems. We rate this charger 4.0 stars out of 5. We were disappointed that we couldn’t charge our car battery for as long as the sun was up. Despite this fact, it's still a decent product that is worth the money. Just don't expect perfection.

Things We Liked

  • Helps extend battery life
  • Solar powered
  • Great warranty

    Extremely affordable

Things We Didn't Like

4.3/5

For people that are looking for a handheld battery charger, the Schumacher SE-5212A 2/10/50 is a great choice. It’s a fully automatic 12 volt battery charger that has safeguards installed to prevent batteries from overheating. It usually takes about 3 – 5 hours to fully charge a car battery, depending on the battery type.

When we found the Schumacher SE-5212A 2/10/50 from reading portable car battery charger reviews, our goal was to find the best portable car battery charger because we wanted something that was compact and transportable. The Schumacher SE-5212A 2/10/50 only weighs about 10 pounds and is fairly small so you can fit this in any car trunk. We were able to successfully store this in the back of our trunk and for those few times where we did need the car battery charger, this really came in handy.

One disappointment that we experienced was that this car battery charger cannot be shipped to Oregon or California. We had lots of great things to say about this charger and we recommended it to a relative of ours. However, much to our surprise, they weren’t able to have it delivered to their residence in California and ended up picking something else.

Even though they can’t ship it to Oregon or California, we still had a great experience with the Schumacher SE-5212A 2/10/50.

Even with the disappointing setback, we still highly favor the Schumacher SE-5212A 2/10/50 and give it 4.3 stars out of 5. It’s compact, lightweight, and fits nicely in the back of our trunk. It quickly charged our car batteries and it didn’t take up much time either.

Things We Liked

  • Prevents battery overcharging
  • Quick charging
  • Handheld design
  • check
    Easy to follow instructions

Things We Didn't Like

  • Cannot be shipped to Oregon or California
  • Not compatible with WM-12 or EC-25 quick connect cables

4.0/5

The Beatit 800A Peak 18000mAh was highly recommended from all the emergency car battery charger reviews we read. If you’re interested in finding the best car battery charger and jump starter, the Beatit 800A Peak 18000mAh is a great choice. With 800 amps of peak current power and heavy duty clamps, it’s able to start your car up to 20 times and more.

Believe it or not, but the Beatit 800A Peak 18000mAh can be easily fit into your glove compartment. We love it! We usually store a ton of things in our trunk so being able to fit this nifty lifesaver in our glove compartment was a game changer.

We will admit that we were star struck when we found out how portable this was and how easily it fit into our glove compartment. However, don’t let this distract you from the fact that it doesn’t work all the time. We tried jump starting a couple of our friends’ car and it was always a hit or miss.

Despite that, it was really nice being able to fit a car battery charger in our glove compartment. We had a really good experience and would still recommend anyone that’s looking for an emergency car battery charger.

Our overall experience convinced us to give the Beatit 800A Peak 18000mAh 4 stars out of 5. We would have given it a stronger rating but having it sometimes work wasn’t enough for us to give it higher ratings. The point of having a car battery charger is making it sure that it always works so the Beatit 800A Peak 18000mAh fell short in this department.

Things We Liked

  • Great jump starter
  • Speedy battery charging
  • LCD screen
  • check
    Intelligent jumper clamps

Things We Didn't Like

  • Instruction manual is difficult to read
  • Customer support nonexistent

3.8/5

The UPG D1724 Sealed Lead Acid Battery Charger is a great charger for lead acid batteries. This battery charger comes with alligator clips that allow you to switch between 6V or 12V. It’s highly affordable and very easy to carry around with.

We want to make it clear that this may damage your car battery so use it at your own risk. We initially bought this charger after reading many lead acid car battery charger reviews. There were a mix of user experiences so we didn’t know what to expect.

We wanted to charge and bring our homemade radio back to life. The grips do not have an indicator light so it’s important that you know what you’re doing. We did use it for our son’s battery operated car and it worked like a charm.

This battery charger isn’t great, but it isn’t terrible either. Although the price is very affordable, remember that you get what you pay for. Overall, we had a very mild experience.

Out of 5 stars, we decided that the UPG D1724 Sealed Lead Acid Battery Charger deserved 3.8 out of 5. It is very low because we felt like this was not a high quality lead battery charger and it comes with the risk that it can damage your car battery too. We would only recommend this battery charger for small situations and certainly discourage anyone from using it on their car battery.

Things We Liked

  • Great for sealed lead acid batteries
  • Portable and lightweight
  • Very affordable
  • check
    Easy to use

Things We Didn't Like

  • Cheap quality
  • Does not have automatic shutoff

4.2/5

The POTEK Smart Battery Charger is one of the best smart car battery chargers we have owned in the last several years. We were testing out different types of battery chargers when we came upon this charger. The POTEK Smart Battery Charger is truly the definition of a smart car charger.

This charger is designed to be smart about charging your car. You have different options for charging and while it is doing its work, you can check the charging amperage, voltage, and percent charged. It also comes preinstalled with an internal fan to keep the temperatures low.

The POTEK Smart  Battery Charger is great for charging high voltage batteries, but it is obsolete if your battery is “too dead.” For some reason, when one of our batteries were really low, this smart charger would not charge the battery. We concluded from our experience that if you want to charge a dead battery, tough luck, but if you want to keep your battery full, then we highly recommend this smart car battery charger.

Luckily, we didn’t have to go through the trouble of trying to charge a really dead battery so our experience has been left intact. We still highly recommend this battery charger as it is a solid piece of work.

We had a decent experience with the POTEK Smart Battery Charger so we decided to give it 4.2 stars out of 5. One area we would like to see improvement on is being able to charge “very dead” batteries.

Things We Liked

  • Great for keeping batteries full
  • Awesome price
  • Amazing for high voltage batteries
  • check
    Comes with different charging options

Things We Didn't Like

  • Very noisy when charging

4.1/5

The STANLEY BC25BS is a great automatic battery charger. One of the best features that many people like is that it automatically selects a charge rate for you to extend and maximize your battery life. Another great feature is that their patented engine helps jump start any car under 2 minutes.

We were very tempted to buy the STANLEY BC25BS when we head many good things about it from our friends. They recommended this because it was a good car battery charger. We were not disappointed.

We used this on two of our cars that we don’t often drive. As you can tell, the batteries were probably close to being dead since the cars were rusting in our garage for over a year. To our surprise, the STANLEY BC25BS was able to bring our car batteries back to life!

We want to mention that one of our friends who used this had blown their batteries out. We are unsure of what caused the malfunction, but this something important to keep in mind. Overall, we were very impressed because the STANLEY BC25BS kept its promise and did start our car in under 2 minutes.

We were really happy with the STANLEY BC25BS but weren’t happy that it destroyed one of our friend’s car batteries. We still want to give this 4.1 stars out of 5 because when it works, it works really well. If the accident was a fluke, we wouldn’t want to discourage anyone from giving this car battery charger a try.


Things We Liked

  • Very affordable
  • Helps jump start cars in under 2 minutes
  • LCD screen
  • check
    Helps extend battery life

Things We Didn't Like

  • Does not charge completely dead batteries

4.5/5

The Battery Tender 021-0123 is a great battery charger for all lead, acid, flooded, or sealed car batteries. It is very compact, portable, and highly cheap. It’s designed to be spark proof with reverse polarity protection and can resume charging if it detects that the battery voltage is low.

We own many cars that have a lead acid battery and we can confidently say that if you do too, then you must own the Battery Tender 021-0123. In our experience, this is one of the best float chargers in the market. Whether you own a lead acid battery or drive a motorcycle, this compact battery charger is your best friend.

On several occasions, we did notice that the Battery Tender 021-0123 was draining our battery rather than charging it. We weren’t sure what the problem was so we sent it back to the manufacturer and they helped us replace it. We didn’t have any problems with our replacement but if you do come across these issues, send it back for a replacement.

Even despite that small setback, we would still highly recommend the Battery Tender 021-0123. We believe that it deserves 4.5 stars out of 5 because the manufacturer was very helpful in getting us our replacement charger. Great customer support from manufacturers is usually the difference between a good and bad experience but luckily for us, we had nothing but positive experiences.

Things We Liked

  • Very cheap
  • Outstanding for lead acid batteries
  • Easy installation
  • check
    Comes with alligator clamps

Things We Didn't Like

If you are looking for a car battery that offers trickle charging, we highly recommend the BLACK+DECKER BC15BD. The BLACK+DECKER BC15BD is one of the most advanced car battery chargers in the market with an LCD screen that tells you the charging and battery status with easy to read icons. It comes with a 3 stage charging feature that automatically switches from fast charge, to top off, to trickle charger.

After reading many trickle charger for car battery reviews, we landed on the BLACK+DECKER BC15BD. Let us start by saying that everything we’ve read about this car battery charger is true. It worked extremely well for our car batteries and best of all, it was very affordable too.

On very rare occasions due to long-use, we noticed that the BLACK+DECKER BC15BD was draining our batteries. We contacted customer support to troubleshoot the issue because we were worried that our unit was defective but after finding out that we shouldn’t use this for long periods of time, the issue was immediately resolved. The BLACK+DECKER BC15BD is great for trickle charging but remember to not use it for extended periods of time.

We highly recommend the BLACK+DECKER BC15BD and give it 4.5 stars out of 5. When the charger was draining our battery, it was mainly our fault. However, what made the experience even better was that the company was willing to replace our unit free of charge if we found it to be defective in the future.

  • One touch automatic charging
  • LCD display
  • Great for AGM, Gel, Wet or Marine 12 volt batteries
  • check
    Great trickle charger

Things We Didn't Like

  • Sometimes drains the battery

The Schumacher SEM-1562A-CA is a revolutionizing car battery charger. It is one of the bestselling chargers of all time and is perfect for charging batteries that are stowed away in storage. It’s both a 6 and 12 volt battery charger that prevents overcharging with a generous 1 year warranty.

We had a couple of batteries that were sitting in our garage that needed a quick charge for use the next day. One of our close friends recommended the Schumacher SEM-1562A-CA because it was reliable, quick, and affordable. We were very happy with the recommendation.

Is there was one area that needs improvement, it would definitely be a set of instructions. The Schumacher SEM-1562A-CA did not come with a set of instructions so it took some experimenting to learn how to fully use the battery charger. After we were familiar with how the charger functioned, everything was great.

The Schumacher SEM-1562A-CA is definitely a battery charger you can count on for a quick charge. It works especially well with batteries laying around in storage. We had a really good experience with the Schumacher SEM-1562A-CA so we want to give it 4.5 stars out of 5.
