Charging Batteries
DANGER
When using an extension cord, use only a three wire extension cord having at least
16 AWG (American Wire Gauge) wire and the same or higher electrical rating as
the device being connected. Use of improper extension cord could result in risk of
fire and electric shock. Three prong to two prong adapters should not be used. Use
of three prong adapters can result in improper grounding and present a shock
hazard to the user.
The use of rubber gloves is recommended when working with batteries.
NEVER attempt to recharge the batteries by attaching cables directly to the battery
terminals.
DO NOT attempt to recharge the batteries and operate the wheelchair at the same time.
DO NOT operate wheelchair with extension cord attached to the AC cable.
DO NOT attempt to recharge the batteries when the wheelchair has been exposed to any
type of moisture.
DO NOT attempt to recharge the batteries when the wheelchair is outside.
DO NOT sit in the wheelchair while charging the batteries.
DO NOT attempt to recharge batteries using both the on‐board battery charger and an
independent battery charger (plugged into the joystick charger port) at the same time.
Doing so will reduce the life of the batteries.
Read and carefully follow the manufacturer's instructions for each charger (supplied or
purchased). If charging instructions are not supplied, consult a qualified technician for
proper procedures.
Ensure the pins of the extension cord plug are the same number, size, and shape as those
on the charger.
DO NOT under any circumstances cut or remove the round grounding plug from the
charger AC cable plug or the extension cord plug.
