6. Life Characteristics of Cyclic Use
7. Charge Characteristic Curve for standby use
8. Storage Characteristic
Supplementary charge required (Carry
out supplementarty charge before use if
100% capacity is requires)
Supplementary charge required before
use. This supplementary charge will help
recovering the capacity and should be
made as early as possible.
Supplementary charge may often fail to
recover the capacity. The battery should
never be left standing till this state is
reached.
Supplementary charge and storage
guidelines.
