Cycle application
Charge method: 2.40V / cell with limited current of 0.25 C
10
(A).
Charge voltage must be adjusted according to ambient temperature, temperature
compensation coefficient is -4mV / cell /
℃
.
When charged capacity is about 105-110% of discharged capacity or in constant voltage case,
the charge current must be kept unchanged for 3 hours in the final stage of charge., charge is
ended.
