roded, clean them with baking soda
and water. Then use a wrench to
loosen and remove the cables from
the terminals. Always disconnect the

nals with a terminal cleaning tool or
wire brush. Reconnect and tighten
the cables, then coat the terminals
with grease.

force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
mechanic do the battery
maintenance.

connected can seriously damage your
car’s electronic controls. Detach the
battery cables before connecting the
battery to a charger.
