2. Operation
A. General
The battery is charged on the aircraft by constant potential.
CAUTION:
The battery is maintenance free. Under no circumstances
should any attempt be made to introduce any substances, eg.,
acid, distilled water or alkali, to the battery.
B. Temperature
Effect
The ideal environmental temperature for battery operation is 20°C(68°F) to
25°C(77°F). Long term exposure to temperatures above 30°C (86°F) can
shorten the life of the battery.
As the temperature falls, the available capacity of the battery is reduced,
which causes a reduction in performance. However, this is not a permanent
condition and the capacity will be restored as the temperature rises. Long
term exposure to low temperatures will not damage the battery. Figure 2
shows variation of available capacity with temperature.
