Owner’s Guide
The ’RUN-TOW/MAINTENANCE/STORAGE’ switch, located under the driver’s seat is set to ‘TOW/MAINTENANCE/
STORAGE’ position for long term storage of the vehicle to avoid draining of the batteries.
During periods of storage, the batteries will need attention to keep them maintained and prevent discharge. In high tem-
peratures the chemical reaction is faster, while low temperatures cause the chemical reaction to slow down. A vehicle
that is stored at 90° F (32° C) will lose.002 of specific gravity each day. If a fully charged battery has a specific gravity of
1.275, and the battery is allowed to sit unused, it will become partially discharged. When it reaches 1.240, which it will do
in less than twenty days, it should be recharged. If a battery is left in a discharged state, sulfating takes place on and
within the plates. This condition is not reversible and will cause permanent damage to the battery. In order to prevent
damage, the battery should be recharged. A hydrometer can be used to determine the specific gravity and therefore the
state of charge of a battery.
In winter conditions, the battery must be fully charged to pre-
vent the possibility of freezing. A fully charged battery will not
freeze in temperatures above -75° F (-60° C). Although the
chemical reaction is slowed in cold temperatures, the battery
must be stored fully charged, and disconnected from any cir-
cuit that could discharge the battery. The controller should be
disconnected from the batteries by setting the Run-Tow/Main-
tenance/Storage switch, located under the passenger seat, to
the ‘TOW/MAINTENANCE/STORAGE’ position. For portable
chargers, disconnect the charging plug from the vehicle
receptacle. For on-board chargers, disconnect the charging
harness from the batteries. The batteries must be cleaned
and all deposits neutralized and removed from the battery
case to prevent self discharge. The batteries should be tested
or recharged at thirty day minimum intervals.
Battery Charging
The battery charger is designed to fully charge the battery set. If the batteries are severely deep cycled, some automatic
battery chargers contain an electronic module that may not activate and the battery charger will not function. Automatic
chargers will determine the correct duration of charge to the battery set and will shut off when the battery set is fully
charged. Always refer to the instructions of the specific charger used.
Do not overfill batteries. The charging cycle will expel electrolyte and result in component damage.
Before charging, the following should be observed:
•
The electrolyte level in all cells must be at the recommended level and cover the plates.
•
The charging must take place in an area that is well ventilated and capable of removing the hydrogen gas that is
generated by the charging process. A minimum
of five air exchanges per hour is recommended.
•
The charging connector components must be in good condition and free from dirt or debris.
