SECTION 8—BATTERIES
42
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
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.
Charger Plugged Into the Joystick
NOTE: For this procedure, refer to FIGURE 8.4.
NOTE: The charger port located on the front of the joystick requires the use of an independent
charger. The independent charger is supplied with the wheelchair.
1. Attach the battery charger connector to
the charger port on the front of the
joystick.
2. Plug the charger’s AC power cord or
extension into the grounded 110-volt
wall outlet.
3. When charging is complete, turn
charger off.
4. Disconnect output cable from joystick
charger port.
