BATTERY CLEANING
Acid-soaked debris on the battery terminal connections will cause current leakage, reduces
battery efficiency, and battery life.
Hose wash battery terminal connections periodically with clean low-pressure water to keep them
free of acid spillage, dirt, and other debris. Do not hose wash electronic controllers, switches,
solenoids and other electrical control devices. Cover as necessary to prevent splashing. Clean
battery terminal connections with baking soda (sodium bicarbonate) and water solution. Mix 5
teaspoons baking soda per quart of water. Use a stiff bristle brush, rinse with clean water and
dry with a clean cloth. Torque connections to 100 in. lbs
NOTICE: The following information does NOT apply to sealed batteries.
1. Check the electrolyte level on new batteries before they are put into service, and, at a
minimum, once a week thereafter. Water use increases as batteries age. If the vehicle is
equipped with a Single Point Battery Watering System see the information on this in this
section.
2. Never allow the electrolyte level (A) to fall below the top of the plates (C). If the plates are
exposed, add only enough to cover the plates before charging.
3. After batteries are fully charged, fill cells to just below the bottom of the cell vents (B),
approximately 1/8” to 1/4”. Electrolyte level should not touch the bottom of the cell vents.
4. Do not overfill batteries. Electrolyte expands and can overflow during charging. Water added
to replace the spillage dilutes the electrolyte and reduces its specific gravity.
5. Use only distilled water. Vehicle batteries may use up to 16 quarts of water during their
useful life and non-distilled water may contain harmful minerals which will have a cumulative
adverse effect on battery performance and life.
6. Check to see that battery cap vent holes are clear. Plugged vent holes will not permit gas to
escape from the cell and could result in battery damage. Check that all vent caps are tightly
in place. Do not allow water or cleaning solution to enter cap vent holes.
NOTICE: Follow local ordinances and codes for proper disposal of battery cleaning
waste.
