Below we have compiled all the information you will require to make the best decision when it comes to choosing a car battery charger.


The first thing to look at when purchasing a car battery charger is the number of amps that it has. Amps represent the level of power output that the charger has. The higher the number of amps, the faster and more powerful the charger is going to be.

Some chargers come in multiple versions with different amp outputs, so you can choose the one that is going to be the safest and most efficient for your car.

Car Battery Charger


The voltage listed on the battery charger is indicative of the type of battery it can charge. Batteries are available in different voltage levels, and you will need to purchase a charger that is compatible with your engine.

Check the power level of the battery you have before buying a charger (this may require looking in your vehicle’s owner’s manual). Some battery chargers are available in a few different models to accommodate different types of batteries.


The size and design of the car battery charger can make a big difference when it comes to how easy it is to carry around and store.

If the battery charger is too big, it’s not going to be convenient to keep in your car or have on hand in your garage, and so you’ll be less likely to actually use it when you need it. Look for a car battery charger that has a smart design, in a size that you can easily carry around.

Types of Batteries Charged

Another very important thing to look at is the types of batteries that your charger can work with. Many chargers are now compatible with several different types of batteries, like lead acid, lithium ion, gel cell, wet cell, AGM, deep cycle batteries, and more.

You will need to read your car’s owner’s manual to determine exactly what type of battery it has and make sure you purchase a charger that works well with it. Many chargers now work on other types of vehicles besides cars as well.

You may be able to use your car battery charger to also recharge batteries for your boat, motorcycle, snowmobile, or lawn mower. If your battery charger is one that works with many different types of vehicles, you will get much better value for money.

LED Lights/Display

The most user friendly car battery chargers have lights or some type of display to indicate the charging status of the car. This display makes the charger much easier to use, and you’ll be more informed about exactly how the charger is working with your battery.

Some battery chargers have LED lights that will change color or blink to indicate the charging status of the battery. Some newer models even have an LED screen which will display a few key indicators about the car battery charger.

Reverse Polarity Protection

Reverse polarity protection is very important for your safety when you are charging the car. Reverse polarity is an electrical phenomenon where the polarization of the wires to and from a power source switch charges, which can cause an electric shock.

Not only is this very dangerous for you as the user, but it can also damage your car and any cords and outlets you are using as well. Reverse polarity and shock protection provide peace of mind while you are charging your car battery.

Maintenance Option

If your car battery dies often, or you are concerned that it might die on a long trip, you may want to look for a car battery charger that has a maintenance option.

This is a setting that will slowly charge your battery to maintain its lifespan and give it the energy it needs to run efficiently. You can buy separate battery maintainers, but for many consumers, it makes the most sense to buy a charger that also has a maintaining function.

Some even double up as battery desulfators that dissolve sulfate that has built up on the lead plates and cause a loss of battery capacity.

This restart option is very helpful to have if your battery dies while you are on the road.

Dust and Water Resistant

Since you will be storing your portable car battery charger in your trunk or garage, it’s important to make sure it can withstand any conditions. A good battery charger should be dust and water resistant, so you won’t have to worry about weather related damage. Of course, you should still always take care to make sure your battery charger is stored appropriately.


With an electrical tool such as a battery charger, it’s always best to make sure you purchase a model that comes with a warranty. A warranty will ensure that if there is any problem with the charger, you can return it to the company and get a refund or a new product.


A good portable battery charger can give you peace of mind, particularly if you are a frequent traveler or often drive in rural areas.
