Cycle application
Charge method: 2.45V / cell with limited current of 0.25 C
20
(A).
Charge voltage should be adjusted according to ambient temperature,temperature compensation
coefficient is -4mV / cell / ℃.
Setting charge capacity as 105-110% of discharge capacity, when the constant charge current keep
as same value for 3hrs, charge end.
Storage
The battery should be fully charged before storage, and then be stored in clean, ventilate and dry
environment without corrosive gas or explosive gas nearby.
Supplementary charge is required in storage period, the method as follows.
