Battery Replacement
A battery wiring diagram is printed on a decal located on
the rear cover. See the specification table for correct battery
specifications.
Battery posts, terminals, and related accessories
contain lead and lead compounds. Wear goggles and
gloves when handling batteries and wash hands after
handling.
The batteries in your power chair should only be
serviced or replaced by a Quantum Rehab Provider or a

table. If you are unable to lift that much weight, be sure
to get help. Use proper lifting techniques and avoid
lifting beyond your capacity.

batteries at the same time.

If the battery condition meter does not light up when you turn
on the power:
„
Check the harness connections. Make sure they are
tight.

Check the circuit breaker. Reset it if necessary.

Check the battery connections.
If the above conditions prove normal, you can load test the
batteries with a battery load tester. These testers are available
at automotive parts stores. Disconnect both batteries before
load testing and follow the directions that come with the load
tester. If either one of the batteries fails the load test, replace
both of them. If your power chair still does not power up,
contact your Quantum Rehab Provider.
