Charging Batteries

WARNING
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 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 recharging the batteries.
DO NOT attempt to recharge the 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 individual instructions for each charger (supplied or
purchased). If charging instructions are not supplied, consult a qualified technician
for proper procedures.
CAUTION
New batteries MUST be fully charged prior to initial use of the wheelchair.
ALWAYS charge new batteries before initial use or battery life will be reduced.
As a general rule, you should recharge your batteries as frequently as possible to
assure the longest possible life and to minimize required charging time. Plan to
recharge them when you do not anticipate using the wheelchair.
