Discharging
The process of drawing power from a battery to supply electrical energy to connected loads.
In addition to deliberately switched-on electrical loads such as heating or lighting, components or devices such as alarm systems or computer memory, so-called silent loads, also draw power from the battery while a vehicle is not in use.
A battery that is no longer fully charged is called discharged; if it is 50% discharged, it is called deep discharged.
