It is advantageous to recharge frequently rather than only
when necessary. In fact, a batterys life is extended if the charge
level is maintained well above a low condition.
REPLACING BATTERIES
NOTE: Invacare recommends that both batteries be replaced
if one (1) battery is defective.

or damaging burns may result. Should the
liquid touch your skin, wash the area IM-
MEDIATELY and thoroughly with cool wa-
ter. In serious cases or if eye contact is
made, seek medical attention IMMEDIATELY.

using a battery cleaning tool, wire brush, or medium grade
sand paper.
NOTE: Upon completion, these areas should be shiny,
not dull.
