10 Best Car Battery Chargers 2021

The most common use for a battery charger is to keep a rarely used vehicle charged during off-season or inactivity. If this is the reason you are looking for a battery it can seem quite straightforward but there are plenty of extra points to consider.

Thinking about everything that you need from a charger will assist you in making the right choice. To help you even further we have compiled a list of all of the best car battery charger models on the market and provided some unbeatable advice on selecting the one that suits you.

Understanding Amp Hours

Find out how many Amp hours your battery stores. An example of a typical size is around 50 Amp hours. Each battery in our list includes an amp measurement; this is an indicator of how quickly the model will charge a battery. A generally used calculation to work out the total charge time is to take the amp hour rating of your battery, divide by the charger amps rating and then add around 10%. For example, a 50 amp battery would take around 6 hours to charge with a 10 amp unit.

• Extra Tip: Skip The Jump Starters. One of the biggest mistakes that buyers make when looking for the best car battery charger is to purchase a jump-starter instead. These devices hold a larger charge that is needed to start an engine when the vehicle’s battery is dead but cannot be used to charge over long periods of time.

How to Choose A Car Battery Charger

After you have chosen the right charger to suit your needs you then have to think about how you are going to use it. This seems like a strange consideration but many buyers make the mistake of not thinking about just how portable the charger is.

Several models on the list are much bulkier than you’d imagine a charger is. If you are looking at moving the charger around a lot or storing it away from home then this is certainly something to keep in mind. By focusing on physical size of the charger as well as the output you will be able to strike the right balance between the two.
