A
No supplementary required
(Carryout supplementary charge before use if 100% capacity is required.)
B
Supplementary charge required before use. Optional charging way as below:
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 2.25Vcell.
3. Charged for 8 ~ 10 hours at limited current 0.05 CA.
C
Supplementary charge may often fail to recover the capacity.
The battery should never be left standing till this is reached.
