death, extreme care must be used with aerosol con-
tainers of battery terminal protectant. Insulate the
metal container to prevent the metal can from con-
tacting battery terminals which could result in an
explosion.
Use care to connect the battery wires as shown (Ref. Fig.
27 on page 21) . Tighten the battery post hardware to 50

Prolonged Storage

Battery charger and controller must be
disconnected since they will contribute
to the premature discharge of batteries. Other electronic devices
may need to be disconnected.
During periods of storage, the batteries will need atten-
tion 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
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 there-
fore the state of charge of a battery.

SPECIFIC GRAVITY ELECTROLYTE FREEZING POINT
Fig. 28 Freezing Point of Electrolyte
In winter conditions, the battery must be fully charged to
prevent the possibility of freezing (Ref Fig. 28 on page
21). A fully charged battery will not freeze in tempera-
tures above -75° F (-60° C). Although the chemical reac-
tion is slowed in cold temperatures, the battery must be
stored fully charged, and disconnected from any circuit
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.

Battery Charging

The battery charger is designed to fully charge the bat-
tery set. If the batteries are severely deep cycled, some
