A
No supplementary charge required
(Carry out 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 limted current 0.25CA and constant volatge 2.25V/cell.
2.Charged for above 20hours at limted current 0.25CA and constant volatge 2.45V/cell.
3.Charged for 8~10hours at limted current 0.05CA .
C
Supplementary charge may often fail to recover the capacity.
The battery should never be left standing till this is reached.
