Prolonged Storage; Battery Charging - Cushman Shuttle 2 Owner's Manual

Read all of this manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notices, Cautions, Warnings, and Dangers.
Use care to connect the battery wires as shown.
Tighten the battery post hardware to 90 - 100 in. lbs. (6 -8
Nm) torque Do not over-torque the terminal stud nut, this

will cause a "mushroom" effect on the battery post which will
prevent the terminal nut from being properly tightened.Pro-

Prologed Storage
Battery charger, controller and other electronic devices need
to be disconnected since they will contribute to the premature
discharge of batteries.
The 'RUN-TOW/MAINTENANCE/STORAGE' switch, located under the passenger seat is set to 'TOW/MAINTE-
NANCE/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 pre-
vent damage, the battery should be recharged. A hydrometer can be used to determine the specific gravity and there-
fore the state of charge of a battery.
In winter conditions, the battery must be fully charged to prevent 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 circuit that could discharge the battery. The controller
should be disconnected from the batteries by setting the Run-Tow/Maintenance/Storage switch, located under the pas-
senger 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 batter-
ies 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 auto-
matic 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.
