0 Supplementary charge required before use.Optional charging way as below:
0 200 400 600 800 1000 1200 1.Charged for above 3 days at limted current 0.25CA and constant volatge 2.25V/cell.
B 2.Charged for above 20hours at limted current 0.25CA and constant volatge 2.45V/cell.
Number of Cycles 3.Charged for 8~10hours at limted current 0.05CA .

Supplementary charge may often fail to recover the capacity.

C The battery should never be left standing till this is reached.
