OPERATION AND SERVICE INFORMATION
If the batteries have been cleaned and any acid in the battery rack area neutralized as recommended, no
corrosion to the battery racks or surrounding area should be present. Any corrosion found should be
immediately removed with a putty knife and a wire brush. The area should be washed with a solution of
sodium bicarbonate (baking soda) and water and thoroughly dried before priming and painting with a
corrosion resistant paint.
The batteries should be placed into the battery racks and the battery hold downs tightened to 45 - 55 in. lbs.
(5 - 6 Nm) torque, to prevent movement but not tight enough to cause distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from the battery terminals or the wire terminals with a
solution of sodium bicarbonate (baking soda) and brush clean if
required.
!WARNING!
To prevent battery explosion that could result in severe personal injury or death,
extreme care must be used with aerosol containers of battery terminal protectant. Insulate the metal
container to prevent the metal can from contacting battery terminals which could result in an
explosion.
Use care to connect the battery wires as shown (Ref Fig. 19). Tighten the battery post hardware to 50 70 in.
lbs. (6 -8 Nm) torque. Protect the battery terminals and battery wire terminals with a commercially available
protective coating.

Prolonged Storage

CAUTION
Battery charger, controller and other electronic devices need to be disconnected since they
will contribute to the premature 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 lose .002 of specific gravity each day. If a fully
