No supplementary charge required(Carry out supplementary charge before use if 100% capacity is required.)

Supplem entary c harge re quired before use.Optional charging way as below:

A

B

C

1.Charged for above 3 days at limited current 0.25CA and constant voltage 2.25V/cell.2.Charged for above 20 hours at limited current 0.25CA and constant voltage 2.45V/cell.3.Charged for 8~10 hours at limited current 0.05CA.

Supplementary charge may often fail to recover capacity.The battery should never be left standing till this is reached.
