Best Car Battery Chargers - Buyer's Guide

voltage

Car batteries are usually available in two variations depending on the voltage. There are the 6-volt and 12-volt batteries. When chopping the best car battery charger in the market, ensure the charger can charge that particular battery you will be using. In case you have multiple cars, each with varying voltage batteries, you should settle for a charger that can effectively charge both battery types.

Charging power (amp)

Charging power is just as crucial as voltage. You will have to ensure you go for a charger with the right Amp to ensure your batteries are correctly charged and maintaining their health. When you choose a charger with Amp lower than the recommended Amp, the battery will take lots of time to charge.  When you settle for a high Amp battery charger, it will also charge your car battery much faster, ending up damaging the battery's health.

operation type

Battery chargers are available in two different operation types. There is the manual and automatic operation type. The automatic battery chargers will help make your job easier. They have microprocessor controlled and will never overcharge the battery and change the charging mode to floating mode to help save energy.

Charging speed

When in the market for a top car battery charger, you should know how fast you want your car charger to be. The car chargers do have different charging speeds due to their different amperages. Before you make any purchase, check how high or low the charger amperage is to help tell how fast the charger can charge your car battery.

Best Car Battery Chargers - FAQs

Is it possible to jump-start my car using the car battery chargers?

Yes, however, not all chargers come with the car jump start feature. In most cases, the smaller battery chargers will never have this feature, as are the older models. This feature is not that important in the car battery chargers, and it is not a priority for most manufacturers, although it helps save the car owner's time if the battery is dead flat.

How can I know the right ampere size of a car battery charger?

The ampere will always be determined by the primary purpose you will be using your battery charger. When you only require it to maintain your battery and then going for a battery charger with an ampere of around 4 Amps will always be enough. In case you need a fast charging charger and maintenance, you will have to go for a charger with a bigger ampere size.

Is it advisable to charge the car battery when it is connected to the vehicle?

If you have a modern car battery charger, you can always do this with active spike protection and monitoring. Current car battery chargers never produce voltage spikes and explain why they are still harmless to charge the battery when connected to the car. However, you should check the user manual before starting charging with the battery still attached to the vehicle.

How long will it take to charge a car battery using a car battery charger?

It will depend on the ampere your car battery charger uses. A car battery will, in most cases, have 48 Amp of electricity. You can always know when you know the battery amp and how much charge it is loading per hour. The 4 amp battery can take up to 12 hours to have a fully charged car battery.
