Temperature Effect on Battery Service Life
Higher temperature will speed up the battery grid corrosion and water loss, thus greatly shorten
the battery life, when the temperature is over 25
℃
, the service life of the battery will be shortened
by half as the temperature increasing by 10
℃
, shown in Figure 3-2.

Charge Requirement
Equalizing Charge and Supplementary Charge
Equalizing charge or supplementary charge is needed in the following cases:
After finish installation, before the battery system is put into operation, the battery bank
should be supplementary charged.
