constant current until the
battery voltage reaches 4.20V at (25±2ºC),
then charges at 4.20V constant voltage,
and gradually reduces the charging
current to less than or equal to 0.01I1 (A).
Take a 10-minute
break. Then the discharge capacity of the battery is measured
during the supply of 0.5I1 (A)
current until the voltage drops
to 3.0V. ≥ 2450Discharge Rate
