Battery Replacement
A battery wiring diagram is printed on a decal located on
the front 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
qualified technician.
Do not replace batteries when seat is occupied.
Power chair batteries are heavy. See specifications
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.
Do not mix old and new batteries. Always replace both
batteries at the same time.
Keep tools and other metal objects away from the battery
terminals. Contact with tools can cause electrical shock.
To replace the batteries:
1. Turn off the power to the controller.
2. Make sure that the power chair is in drive mode. See
“Your Power Chair.”
3. Loosen the rear pivot hardware until the Nylock nut is a
few threads from being removed.
4. Remove the detent pin from the top of the actuator. See
figure 4. If there is any difficulty in reaching the pin from
under the seat, the seat pan may be removed. Remove
six (6) Phillips flat head screws to remove the seat pan.
5. Pivot the seat toward the rear of the power chair and
support the seat in this position. Take care to ensure that
the recline actuator does not damage the rear door of
the power chair while the seat is pivoted rearward.
6. Remove the front cover by squeezing the release
handles (see figure 21) and lifting the front cover up
and away from the power base.
7. Remove the top cover by lifting it straight up and off of
the power chair.
8. Disconnect the actuator harness.
9. Disconnect the quick release battery connectors. See
