It is advantageous to recharge frequently rather than only
when necessary. In fact, a battery’s 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.

ter. In serious cases or if eye contact is
made, seek medical attention IMMEDIATELY.
