Electrolyte Level and Water
Maintaining correct electrolyte level is important because any part of
the plates open to air will be damaged.
Do not overfill batteries with water. Too much water pushes the elec
-
trolyte from the battery by release of gas and a decrease in volume of
the electrolyte.
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.
NOTICE: DO NOT overfill batteries. The charge cycle will expel
electrolyte and cause component damage in overfilled
batteries.
As a battery is being charged, it produces hydrogen gas. Most of this
gassing occurs at the end of the charge cycle. Hydrogen gas 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 surface below the vehicle. Sulphuric acid loss will weaken the amount of acid within the elec -
trolyte and decrease the life of the battery.
Over the life of the battery, a large amount of water is used. The water added to the batteries must be clean and with
-
out contamination. Unclean water 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 following water purity
table for requirements.
The electrolyte in a battery is an acid solution which can cause severe burns to the skin
and eyes. Clean all electrolyte spills to the body and eyes with clear water. Contact a
physician immediately.
Always wear a safety shield or approved safety goggles when you add water or charge the bat -
teries.
