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.

Capacity_1

After standard charge, measure time taken for a fast
discharge.

110 minutes or more

Charge/Discharge
Cycle

After repeating standard charge and fast discharge,
measure the fast discharge time after 300 discharge
cycles.

90 minutes or more

Capacity_2

After standard charge, measure the time taken for a
standard discharge.
