Temperature Affects Battery Capacity
Battery storage capacity is affected by the temperature; the
colder it is, the less energy it is able to store; as temperature
increases, so does the storage capacity of the battery.
The ideal battery temperature for deep cycle batteries is
77°F (25°C). At 32°F (0°C) the storage capacity of the bat-
tery will be reduced by 20%. This means in cold weather the
vehicle will not travel as far as it would in warm weather.
Electrolyte Level and Water
The correct level of the electrolyte is 1/2” (13 mm) above the
plates in each cell.
This level will leave approximately 1/4” - 3/8” (6 - 10 mm) of
space between the electrolyte and the vent tube. The elec-
trolyte level is important since any portion of the plates
exposed to air will be ruined beyond repair. Also avoid filling
with too much water, which will result in electrolyte being
forced out of the battery due to gassing, and a decrease in
volume of the electrolyte that results from the charging cycle.
DO NOT overfill batteries. The charging cycle will
expel electrolyte and result in component damage.
If the battery electrolyte level is too high, the electrolyte will
block the vent tube and the gas will force it out of the vent
tube and battery cap. The water will evaporate but the sulfuric
acid will remain where it can damage vehicle components and
the storage facility floor. Sulfuric acid loss will weaken the
concentration of acid within the electrolyte and reduce the life
of the battery.
