Standard Discharge
Note: Standard charge is defined as charging with constant voltage limit of 4.2V
and constant current limit of 0.9A; the termination charge occurs when
the current drops to 45mA.

Standard discharge is defined as discharging at a constant current of
350mA until the battery protection circuit switches the battery output off in
over-discharge mode.
