Best answer: Is a battery charger a rectifier?

How does a battery charger function?

How a battery charger works. A battery works by converting its stored chemical energy into electrical power. Once the electrolyte of the battery is used up, it needs to be recharged. A battery charger is a device that provides Direct Current (DC) to the battery to restore the used-up electrolyte.

What is a battery charger rectifier?

A rectifier transforms alternating current (AC) into direct current (DC). Its normal function is charging batteries and keeping them in optimum conditions while, at the same time, providing DC power for other loads.
