Check the battery terminals for
corrosion (a white or yellowish
powder). To remove it, cover the
terminals with a solution of baking
soda and water. It will bubble up and
turn brown. When this stops, wash it
off with plain water. Dry off the
battery with a cloth or paper towel.
Coat the terminals with grease to
help prevent future corrosion.
If the terminals are severely cor-
roded, clean them with baking soda
and water. Then use a wrench to
loosen and remove the cables from
the terminals. Always disconnect the
negative ( ) cable first and recon-
nect it last. Clean the battery termi-
nals with a terminal cleaning tool or
wire brush. Reconnect and tighten
the cables, then coat the terminals
with grease.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damage to the car's
electrical system.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
mechanic do the battery
maintenance.
