Do battery chargers use AC or DC?

1 Answer

Battery chargers typically use AC (alternating current) from the power outlet. However, the charger converts this AC into DC (direct current) to charge the battery.

Here's how it works:

AC Input: The charger takes the AC power from the wall socket.

AC to DC Conversion: Inside the charger, there is a component called a rectifier that converts the AC into DC.

Voltage Regulation: The charger then adjusts the DC voltage and current to match the requirements of the specific battery.

Battery Charging: Finally, the DC current is supplied to the battery to charge it.

So, the charger uses AC from the outlet, but the battery itself needs DC to charge.
