and result in extreme overheating. The charger should be checked after 24 hours and unplugged
after the charge cycle is complete.
Before charging the batteries, inspect the plug of the battery charger and vehicle receptacle housing for dirt or
debris.
Charge the batteries after each day's use.

• Inspect all wiring for fraying, loose terminations, corrosion or deterioration of insulation.
• Check that the electrolyte level is correct and add suitable water as required.
• Clean the batteries and wire terminations.
• Coat battery terminals with commercially available protectant.

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
electrolyte level is important since any portion of the plates exposed to air will be ruined beyond repair. Also avoid fill-
ing 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.
A battery being charged will 'gas' with the majority of the gssing taking place at the end of the charging cycle. This
gas is hydrogen with 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 minimal. 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 sulphuric
acid will remain where it can damage vehicle components and the storage facility floor. Sulphuric acid loss will
weaken the concentration of acid within the electrolyte and reduce the life of the battery.
