Optional charging method as below:
1. Charged for above 3 days at limited current 0.25C and constant voltage 2.25V/cell
2. Charged for above 20 hours qat limited current 0.025C and constant voltage 2.45V/cell
3. Charged for 8~10 hours at limited current 0.05CA.
Supplementary charge may often fail to recover the capacity.
the battery should never be left standing until this is reached.
