8.3.1.2 Standard Discharge

Note: Standard charge is defined as charging with constant voltage limit of 4.2V and con-
stant 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.

After standard charge, measure within
24 hours.
After standard charge, measure time
taken for a fast discharge.
After repeating standard charge and
fast discharge, measure the fast dis-
charge time after 300 discharge cycles.
After standard charge, measure the time
taken for a standard discharge.
After standard charge, apply a standard
discharge followed by a standby dis-
charge. Then measure capacity after
carrying out standard charge and then a
fast discharge.
After a standard charge, keep battery at
25°C for 30 days. Measure the time
taken for a fast discharge.
