DESCRIPTION
On gasoline engine equipped vehicles, a flexible
thermal guard wraps around the battery case to
enclose the sides of the battery (Fig. 22). The thermal
guard consists of a plastic cloth outer skin with a
polyester based insulator fiber.

OPERATION

The thermal guard protects the battery from
engine compartment temperature extremes. The tem-
perature of the battery can affect battery perfor-
mance. The air trapped in the thermal guard creates
a dead air space, which helps to insulate the sides of
the battery case from the air temperature found in
the surrounding engine compartment.
