Battery Charger Operation - Pronto M61 Owner's Operator And Maintenance Manual

SECTION 11—BATTERIES
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.
NOTE: The batteries can be charged using the on-board battery charger or by plugging an
independent battery charger into the port located on the front of the joystick.

Battery Charger Operation

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.
NEVER leave the charger unattended when the charger circuit breaker is tripping.
Use of improper extension cord could result in risk of fire and electric shock.
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.
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.
NOTE: For this procedure, refer to FIGURE 11.4.
NOTE: The charger port located on the front of the joystick requires the use of an independent
charger. The independent charger is NOT 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 230-volt wall outlet.
