AT EACH CHARGING CYCLE

To reduce the possibility of fire, never attach a
battery charger to a vehicle that is to be unat-
tended beyond the normal charging cycle.
Overcharging could cause damage to the vehi-
cle batteries and result in extreme overheat-
ing. 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.

MONTHLY

• 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 avail-
able 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 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

A battery being charged will 'gas' with the majority of the
gassing taking place at the end of the charging cycle.
Qty.
This gas is hydrogen which is lighter than air. Water and
sulfuric acid droplets will be carried out of the battery
vents by the hydrogen gas, however, this loss is mini-
mal. If the battery electrolyte level is too high, the elec-
trolyte 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 bat-
tery.

Fig. 20 Correct Electrolyte Level
Over the life of the battery, a considerable amount of
water is consumed. It is important that the water used
be pure and free of contaminants that could reduce the
life of the battery by reducing the chemical reaction. The
water must be distilled or purified by an efficient filtration
system. Water that is not distilled should be analyzed
and, if required, filtration installed to permit the water to
meet the requirements of the water purity table (Ref.
Fig. 21).
Even if the water is colorless, odorless, tasteless and fit
for drinking, the water should be analyzed to see that it
does not exceed the impurity levels specified in the ta-
ble.
