Best Car Battery Chargers Reviews in 2018


Flat battery is a matter of concern when we are in need of travelling but fail to ignite the car engine. Firstly, what pops into your head when you are in this state? Waiting for a second car to come and give you a jump start! Oh! That would be time-consuming and costly!

A home car battery charger will tackle this problem and you will no longer suffer the inconvenience of waiting. The charger will bring a battery from low charge to full charge. Besides, it helps maintain, condition your battery and keep it healthy, from dying and also increase the lifespan of the battery in a vehicle you use infrequently.

What kind of charger is right for your car battery?

To avoid defects in use, you should know what type and size of a charger goes with your car battery. In our automotive battery charger reviews below, we’ve listed 10 high-quality chargers which would work with both small and large batteries. You may have a look at the following tips to pick a right car battery charger.

Selecting a car battery charger based on your car battery type

There are many different types of batteries such as wet cell (flooded), maintenance-free, AGM, gel cell or VRLA (valve-regulated lead acid), etc. Normally, one charger is compatible with all types except gel cell. Nevertheless, some of gel-cell car chargers work well with other car battery types.

Identifying your car battery size and choosing the most suited charger

In this step, you need to know about your car battery capacity (written in Ah) that you could find it on the battery label located on the top or side of the battery. For instance, a 100Ah battery would need a charger with a charging rate of 10A to recharge the battery from complete discharge to full charge in 12 hours.

Another example is a car battery rated at 50Ah. It would take 6 hours for a 10A charger to recharge a flat battery to 100% full charge. To calculate your total charge time, take the ampere hour rating of your car battery (Ah) and divide by charging rate of the charger (A) and then multiply by 1.2 (20% of efficiency loss). Thus, the higher charging rate of charger, the faster your battery reaches full charge.

Selecting a car battery charger based on usage conditions

Each car battery charger has different features for versatile uses and flexibility, so you should compare one to another carefully to avoid regret after you buy.

The following points are examples for you.

  • Multi-voltage input power chargers are good for those who travel abroad frequently.
  • Waterproof chargers are for using in wet environment.
  • Multi-bank chargers are for charging more than one batteries at the same time.

The following is our top 10 automotive battery chargers you may read on to find out which one is the best for your vehicle.
