Refilling a Low Battery
The normal charge/discharge cycle of a battery causes the cells to give off hydrogen and oxygen. These gases
are the ingredients of water . Because of the loss of these gases and the lowering of the electrolyte level, it will be
necessary to add pure, clean distilled water to bring the fluid to the proper level. After filling, charge the battery to
raise the specific gravity to the fully charged (1.270 or greater) position.
Off-season Storage
To prevent battery damage during extended periods of non-use, the following basic battery maintenance items
must be performed:
S Remove battery from machine and wash case and battery tray with a mild solution of
baking soda and water. Rinse with lots of fresh water after cleaning. NOTE: Do not
get any of the baking soda into the battery or the acid will be neutralized.
S Using a wire brush or knife, remove any corrosion from cables and terminals.
S Make sure electrolyte is at proper level. Add distilled water if necessary.
S Charge at a rate no greater than 1/10 of the battery’ s amp/hr capacity until the electro-
lyte’s specific gravity reaches 1.270 or greater.
S Store battery either in machine with cables disconnected, or store in a cool dry place.
NOTE: Stored batteries lose their charge at the rate of 1% per day. They should be
recharged to a full charge every 60 to 90 days during a non-use period. If stored during
the winter months, the electrolyte will freeze at a higher temperature as the battery dis-
charges. The chart below indicates freezing points by specific gravity.

Charging Procedure
Charge the battery with a charger no larger than 1/10 of the battery’ s amp/hr rating for as many hours as needed to
raise the specific gravity to 1.270 or greater.
WARNING
The gases given off by a battery are explosive. Any spark or open flame near a battery can cause an explosion
which will spray battery acid on anyone close to it. Battery acid will cause burns to skin. In case of contact with
battery acid, wash the affected area with large quantities of cool water and seek immediate medical attention.
