Storage
The battery should be stored in clean and dry environment .
Storage time: battery is ex-work in fully charged,storage time should be limited,for ensuring battery
performance,storage time please do not exceed following time:
Under 25
℃
, six months
Under 30
℃
, three months
Under 40
℃
, six weeks
The battery supplemental charge method during the storage is: charge battery with 2.35V/cell for 8
to 12 hours.
It is necessary to limit the current, and the optimum limiting value is within 0.2C10 ( A ) .
Testing of the open circuit with the storage battery can decide whether it shall be supplemental
charged. If the voltage drops to 2.10V/cell, the battery shall be supplemental charged in time.
Improper maintenance will shorten the battery service life or decrease the service performance.
