Acura 2011 TL Owner's Manual page 546

To see the battery label, remove the
left side engine compartment cover
(see page 508 ).
Check the terminals for corrosion (a
white or yellowish powder) after
removing all engine compartment
covers (see page 508 ). To remove
corrosion, 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.
WARNING: Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
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.
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
technician do the battery
maintenance.
