Whether you are an experienced or first-time power chair user, your wheelchair batteries keep your complex wheelchair running, so you can keep on living your life! While you’ll receive a set of brand-new batteries when you get your new power chair, it’s normal to have to replace the batteries from time to time. When the time comes to replace your batteries, you might ask yourself: what kind of batteries does my wheelchair use? We’re here to explain the type of batteries your complex rehab power wheelchair needs and where you can purchase them!
Understanding Your Complex Wheelchair Batteries

Your Quantum complex rehab power wheelchair uses two long-lasting, 12-volt, deep-cycle batteries. These batteries are sealed and maintenance free. Since they are sealed, there is no need to check the electrolyte fluid level. Deep-cycle batteries are designed to handle a longer and deep discharge. Though they are similar in appearance to batteries you find in a vehicle, they are not interchangeable. Car batteries are not designed to handle a long, deep discharge, and are also unsafe for use in power wheelchairs.
Always use two batteries of the exact same type, chemistry and amp-hour capacity. We recommend deep-cycle batteries, such as AGM and Gel Cell. Click to learn more about best charging practices for your complex wheelchair.
