BATTERY CHARGING
The battery charger is designed to completely charge the battery set. The automatic charger determines the correct
length of charge for the battery set and turns off when the batteries are charged. Always refer to the instructions sup -
plied with the charger. See Appendix A for charger operating instructions.
BATTERY PROLONGED STORAGE
Improper storage may damage, destroy or cause permanent loss of battery capacity. Do not exceed storage
time or temperature limits. Batteries must be charged to the correct level before storage. Storing fully
depleted batteries will make them permanently unusable.

The optimum storage temperature range is between 65°F and 82°F (18°C and 28°C)
• Charge the battery module based on climate during storage period.
– In cold climates, fully charge the battery module. Make sure that the charging operation is complete and there
are no faults displayed on the charger. The green light on the charger should be on indicating the charge cycle is
complete.
