Acura 2009 Accord Sedan - Manual (Page 583)

Check the condition of the battery
monthly by looking at the test
indicator window. The label on the
battery explains the test indicator’s
colors.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative (
) cable first, and
reconnect it last.
Check the terminals for corrosion (a
white or yellowish powder) after
removing all engine compartment
covers (see page
). 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 further corrosion.
If additional battery maintenance is
needed, see your Acura dealer or a
qualified technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
