SECTION 8—BATTERIES
At’m and At’m QT 52 Part No. 1125078
Charging Batteries
ƽ 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.
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.
Basic concepts which will help you understand this automatic process are:
The amount of electrical current drawn within a given time to charge a battery is called
“charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is
high. As a charge builds up, the charge rate is reduced, and the battery charger rate
decreases to a “trickle charge”.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they
may need to be replaced. Contact a qualified technician.
Charging Using an Independent Charger
ƽ WARNING
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
Only use a charger approved by Invacare when charging through the joystick on this
wheelchair model.
DO NOT use an independent charger with an output rating of over 8A (Amps).
Otherwise, damage may occur.
