2 Precaution when Charging or Storing Batteries
The capacity of battery will be affected and its service life shortened in any of the following cases
while it is recharged, discharged or stored.
1) Recharging
Fig. 1 shows how ambient temperature at recharging is related to charging efficiency or as affect-
ing discharge capacity. As seen from the figure, charging at normal temperature is best, and the
efficiency decreases as the temperature rises. It is best, therefore, to always recharge the battery
at normal temperature to obtain full use of battery capacity and enjoy maximum operation per
charge. And the service life of your battery will be shortened if it is frequently overcharged or
recharged at high temperature.
2) Discharge
Fig. 2 shows discharge temperature characteristics. Discharge characteristics at high tempera-
ture are the same as those at normal temperatures. The battery is likely to have reduced dis-
charge capacity as well as lower discharged voltage when discharged at low temperature. And
the service life of your battery will be shortened if it is greatly overcharged.
Note:
0.1C charge means that the battery is recharged with 0.1 -time current as against its capacity.
Note:
1C discharge means one with 1 -time current over battery capacity.
3) Storage
See Fig. 3 for how storing period at different temperature levels is related to the remaining capac-
ity. The battery will lose its capacity as storage temperature rises and the storage period increas-
es. This does not mean, however , that the battery performance is damaged when the battery is
stored. The battery, reduced in capacity, will be restored once it is recharged. Always recharge
your battery
before use. And recharge and discharge the battery 3 or 4 times to restore its capacity if it has
been stored for a long period or at high temperature. Storing at high temperature can adversely
affect the service life of your battery.
Your battery has been fully charged before leaving the factory, but its capacity may be affected
considerably when it takes several months to reach you, if it is stored at high temperature area or
passes through a high-temperature region. Then, the battery must be recharged and discharged
3~4 times to fully restore its capacity.
And the battery should always be stored at normal temperature or lower if it will not be used for
any long period. This helps your battery have a longer service life.
