Ambient temperature Vs. Battery Life
The heat disseminates performance of VRLA battery is bad, it’s liable to cause heat run away
when heat accumulates. When temperature exceeds 25℃, the battery life will decrease half per
10℃ temperature raise.

Ambient temperature elevating, also will accelerate the battery slab lattice corrosion and the
battery moisture content loss, thus will greatly reduce the battery the life. So suppose to
control the ambient temperature, after the quantity of heat accumulating to the certain degree
can damage the battery, seriously will be able to cause hotly loses control. If indoor
temperature reaches too high, improves the ambient temperature. The battery spacing cannot
to be lower than 10mm, at the same time according to handbook request regulating cell
floating and Equalization voltage value.
