Warnings for Handling and Replacing Batteries
ƽ WARNING
Make sure power to the wheelchair is Off before performing these procedures.
The use of rubber gloves 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.
Use MK p/n M24SLDG or p/n M22NFSLDG batteries only. 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.
Install protective caps on POSITIVE (+) and NEGATIVE (-) battery terminals.
DO NOT remove fuse or mounting hardware from POSITIVE (+) RED battery
cable mounting screw.
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 existing or
new battery(ies), clean the baking soda from the battery tray or battery(ies) being sure to avoid
contact with skin and eyes. Determine source of contamination. Never install/reinstall a battery
with a cracked or otherwise damaged case.
