WARNING
ALWAYS use a battery lifting strap when lifting a
battery. It is the most convenient method and
assures that the battery acid will not spill. It also
helps to prolong the life of the battery.
DO NOT tip the batteries. Keep the batteries in
an upright position.
NOTE: If there is battery acid in the bottom or on the
sides of the battery box(es) or battery(ies), apply baking
soda to these areas to neutralize the battery acid. Be-
fore reinstalling the NEW or existing battery(ies), clean
the baking soda from the battery box(es) or battery(ies).

Attempting to “wedge” a battery into a battery
box may damage the box and/or the battery.
