Warnings For Handling and Replacing Batteries

WARNING
After any adjustments, repair or service and before use, make sure that all attaching
hardware is tightened securely - otherwise injury or damage may result.
Make sure power to the wheelchair is Off before performing this section.
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.
U1 batteries weigh 24 pounds each. Use proper lifting techniques (lift with your
legs) to avoid injury.
Use U1 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 handle/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 cables to contact both battery posts
at the same time. An electrical short may occur and serious personal injury or
damage may occur.
The POSITIVE (+) battery cable MUST connect to the POSITIVE (+) battery
terminal, otherwise serious damage will occur to the electrical system.
Connect same color connectors to each other (RED to RED, BLACK to BLACK).
DO NOT remove fuse or mounting hardware from POSITIVE (+) battery cable
mounting screw. To replace the fuse, obtain and replace battery harness with fuse.
Wheelchairs should be examined during maintenance for signs of corrosion (water
exposure, incontinence, etc.). Electrical components damaged by corrosion should
be replaced IMMEDIATELY.
Wheelchairs that are used by incontinent users and/or are frequently exposed to
water may require replacement of electrical components more frequently.
NOTE: If there is battery acid in the bottom of the battery tray or on the sides of the battery, apply
baking soda to these areas to neutralize the battery acid. Before reinstalling the existing or new
battery, clean the baking soda from the battery tray or battery 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.
