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.

much weight, be sure to get help. Use proper lifting techniques and avoid lifting beyond your
capacity.
