Maintenance
Read all of SAFETY and this section before attempting any procedure.
Pay particular attention to Notices, Cautions, Warnings and Dangers
DO NOT overfill batteries. The charge cycle will expel electrolyte and cause
component damage.
A battery being charged will gas with most gassing occurring at the end of
the charging cycle. This gas is hydrogen which is lighter than air. Water and
sulphuric acid droplets will be carried out of the battery vents by the hydrogen
gas, however, this loss is minimum. If the electrolyte level is high, the electrolyte
will block the vent tube and the gas will push it out the vent tube and battery
cap. The water will dry but the sulphuric acid will stay and damage the vehicle
components and the storage facility floor. Sulphuric acid loss will weaken the
amount of acid within the electrolyte and decrease the life of the battery.
Over the life of the battery, a large
amount of water is used.
The water used must be clean
and without contamination.
Water that is not clean decreases
the life of the battery by reducing
the chemical reaction.
Use distilled water or filtered
water only. Test water that is not
distilled water and filter if needed.
Refer to the water purity table
for requirements.
