Charging Batteries

ƽ WARNING

NEVER attempt to recharge the batteries by attaching cables directly to the

battery terminals or clamps. ALWAYS use the recharging plug located on the back

of the joystick.

DO NOT attempt to recharge the batteries and operate the power wheelchair at

the same time.

During use and charging, unsealed batteries will vent hydrogen gas which is

explosive in the right concentration with air.

CAUTION

Always charge new batteries before initial use or battery life will be reduced.
