Float Charging Characteristics

No supplementary charge required

(Carry out supplementary charge before use if 100% capacity is required.)

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 .

Supplementary charge may often fail to recover the capacity.

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