Prolonged Storage - Cushman 623525-H 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.

PROLONGED STORAGE

Battery charger, controller and other electronic devices need to be disconnected since they will contribute to the pre-
mature discharge of batteries.
During periods of storage, the batteries will need attention to keep them maintained and prevent discharge.
In high temperatures 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 loose.002 of specific
gravity each day. If a fully charged battery has a specific grav-
ity 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 (P/N
50900-G1) 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. 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.
