The Functions of Car Battery Charger

It starts with AC in 120 volts from an outlet, and it is changed to 12 volt DC to be available for the car’s battery. It’s the low voltage, as it is the ideal one for charging a dead battery.

High voltage can be dangerous as it can cause an explosion. Quick charging is not advisable as it can cause damages to the batter and put human lives in danger. On the other hand, a charger with a high charger output can charge quickly. 

The car battery usually carries 48 amp-hours. An amp brings 48 hours to the engine, while two amps are for 24 hours. Six amps are down for 8 hours, and so on.

Overheat can occur, and it can escalate to an explosion. It should have a timer that can stop charging once the battery is full.

It’s helpful if a charger has circuits and a microprocessor controller. These parts are capable of sensing temperature and voltage.
