Types of Car Battery Charger

The car battery charger to use will depend on the type and size of the battery that is being charged. Some battery types can withstand overcharging while other types cannot. They require manual disconnection or the specific type of charger with voltage sensing circuits.

So, it is important to choose the right type of car battery charger suitable for the charger you are using.

1) Simple Charger – The simple type of car battery charger can simply supply a constant DC power source into the battery you are charging. It doesn’t alter the power output based on charge or time of charging which means it needs manual disconnection when the battery is fully charged to avoid overcharging.

This is the least expensive of all the car battery charger types; however, it often takes a longer time to charge a battery.

2) Trickle Charger – The best trickle chargers have low current battery charger of about 1 to 1500 mA. It is typically used for small capacity batteries from 2 to 30 Ah or batteries in cars, boats, and RV’s with less than 30 Ah.

3) Time-Based Battery Charger – The timer-based car battery charger is the most common among the high-capacity Ni-Cd cells. The power output of this type of battery charger is terminated after a certain time set.

4) Smart Battery Charger – A smart type of car battery charger can monitor the voltage of the battery, time, and temperature of the charge to identify the maximum charge current. The power output given by a smart car battery charger will depend on the battery’s state. It will automatically terminate the charging when the optimum charge is achieved.

This type of car battery charger is also much faster to charge batteries compared to the others but is often more expensive.

Buying Guide: Specs and Features to Look for in a Battery Charger
