Off-Season Storage

To prevent battery damage during extended periods of non-use,
the following basic battery maintenance items must be
performed:
• Remove the battery from the machine and wash the
case and battery tray with a mild solution of baking
soda and water. Rinse with lots of fresh water after
cleaning.
• Using a wire brush or knife, remove any corrosion from
the cables and terminals.
• Charge at a rate no greater than 1/10 of the battery's
amp/hr capacity.
• Store the battery either in the machine with the cables
disconnected, or store in a cool place.
NOTE: Stored batteries lose their charge at the rate
of 1% per day. Recharge to full capacity every 30 to
60 days during a non-use period. If the battery is
stored during the winter months, electrolyte will
freeze at higher temperatures as the battery
discharges. The chart below indicates freezing
points by specific gravity.

Battery Charging

If battery voltage is 12.8 V or less, the battery may need
recharging. When using an automatic charger, refer to the
charger manufacturer's instructions for recharging. When using
a constant current charger, use the following guidelines for
recharging.
NOTE: Always verify battery condition before and 1-
2 hours after the end of charging.
An overheated battery could explode, causing
severe injury or death. Always watch charging
times carefully. Stop charging if the battery
becomes very warm to the touch.
Allow it to cool before resuming charging.
