Disconnecting Battery Cables
Connecting Battery Cables
When to Charge Batteries
Charging Batteries
Replacing Batteries
Make sure power to the wheelchair is OFF before performing this procedure.
The use of rubber gloves and chemical goggles is recommended when working
with batteries.
Invacare strongly recommends that battery installation and battery replace-
ment always be done by a qualified technician.
After ANY adjustments, repair or service and BEFORE use, make sure all
attaching hardware is tightened securely - otherwise injury or damage may
result.
This procedure MUST be performed while the wheelchair is unoccupied.
REMOVING/INSTALLING BATTERIES (FIGURE 1)
Each battery weighs 35 pounds. Use proper lifting techniques (lift with your legs)
to avoid injury.
Failure to use the correct battery size and/or voltage may cause damage to
your wheelchair and give you unsatisfactory performance.
ALWAYS use a battery lifting strap when lifting a battery. It is the most conve-
nient method and assures that the battery acid will not spill. It also helps to
prolong the life of the battery.
DO NOT tip the batteries. Keep the batteries in an upright position.
NOTE: If there is battery acid in the bottom of the battery tray or on the sides of the battery(ies), apply
baking soda to these areas to neutralize the battery acid. Before reinstalling the NEW or existing battery(ies),
clean the baking soda from the battery tray or battery(ies).
REMOVING (FIGURE 1)
1. Place the wheelchair in a well ventilated area where work can be performed without risking
damage to carpeting or floor covering.
