WARNING
Make sure power to the wheelchair is OFF before performing this procedure.
The use of rubber gloves and chemical goggles or face shield is recommended
when working with batteries.
Invacare strongly recommends that battery installation and battery
replacement 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.
22NF batteries weigh 37 pounds each. GP24 batteries weigh 51 pounds
each. 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
convenient 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.
NEVER allow any of your tools and/or battery cable(s) to contact BOTH
battery post(s) at the same time. An electrical short may occur and serious
personal injury or damage may occur.
When tightening the clamps, always use a box wrench. Pliers will “round
off” the nuts. NEVER wiggle the battery terminal(s)/post(s) when
tightening. The battery may become damaged.
The POSITIVE (+) RED battery cable MUST connect to the POSITIVE (+)
battery terminal(s)/post(s), otherwise serious damage will occur to the
electrical system.
The warranty and performance specifications contained in this manual are
based on the use of deep cycle gel cell batteries. Invacare strongly
recommends their use as the power source for this unit.
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).
