8.3.2.2Standard 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.

Acceptance Test	Specifications

Capacity_2		After standard charge, measure the time taken for a	500 minutes or more
		standard discharge.
		After standard charge, apply a standard discharge
