3. Ambient Temperature, Capacity and Life
3.1 Relationship between Ambient Temperature and Capacity
VRLA batteries can be used in very low or high temperature (below -15
º
C or
above 45
º
C). However the battery data such as capacity life and floating voltage are
measured with temperature between 20º C-25º C as a standard. The capacity of the
battery will decrease with lower temperature as shown in Fig. 3-1 below.
Fig.3-1: Ambient Temperature vs. Available Capacity
As represented by the graph above, the capacity of the battery will decrease when
the temperature is too low. For example, if the temperature decreases from 25º C to
0º C, the capacity will be decrease to85% of the nominal capacity. The battery will be
in a less-charged state with lower temperature and this will lead to battery failure in
discharging and the active material in the negative plate to saltilize.
