8.3.2.2 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.
Acceptance Test Specifications
10 Short-circuit delay time 160µs 200µs 240µs
11 Recovery charge current 0.5mA 1mA 2mA
Description Condition Standard
Open circuit voltage After standard charge, measure within 24 hours. 4.15V or more
Internal Resistance After standard charge, measure within 24 hours. 150 m max.
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. 500 minutes or more
Over Discharge
After standard charge, apply a standard discharge
followed by a standby discharge. Then measure
capacity after carrying out standard charge and then a
fast discharge.
110 minutes or more
Self discharge After a standard charge, keep battery at 25°C for 30
days. Measure the time taken for a fast discharge. 100 mins or more
Temperature
Perform a standard charge and fast discharge at 0°C,
25°C and 40°C and measured the time taken for a
fast discharge at 25°C.
100 mins. @ 0°C
110 mins. @ 23°C
105 mins. @ 40°C
