How to Discharge a Battery?
Discharging a battery refers to the process of using up the stored energy in the battery to power a device. To understand battery discharge, it is important to first understand the chemical reactions and energy release that occur in a battery, as well as the different types of batteries and their discharge characteristics.

Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
