Most mobility scooters and power chairs use two long-lasting, sealed, deep-cycle batteries. These batteries are maintenance-free, so you do not need to check electrolyte levels.
Deep-cycle batteries are designed for longer and deeper discharges than standard vehicle batteries. Vehicle batteries are not suitable for mobility devices because they are not designed to handle extended use and deep discharges.
For optimal performance and longevity:
-
Always use two batteries of the same type, chemistry, and amp-hour (Ah) rating.
-
Use the charger provided with your mobility device, as it is designed specifically for safe, efficient charging.
Off-Board Charging
Most mobility devices use off-board chargers, which are separate from the scooter or power chair. To charge safely:
-
Position your mobility device next to a standard electrical outlet.
-
Make sure the controller is turned off.
-
Plug the charger into the device’s charging socket.
-
Plug the charger into the electrical outlet.
-
When the batteries are fully charged, unplug the charger first from the outlet, then from the device.
Many chargers have LED indicators showing power on, charging in progress, or charging complete. If your device does not fully charge within 24 hours, unplug the charger and contact your dealer.
Breaking In New Batteries
New batteries require a few charging cycles to achieve peak performance and long life:
-
Fully charge any new battery before initial use to reach approximately 90% of its capacity.
-
Operate the device slowly at first, indoors or in a safe area, to break in the batteries.
-
Recharge fully for 8–14 hours and use again.
-
After 4–5 charging cycles, your batteries should reach 100% capacity and deliver maximum performance.
Charging Frequency
How often you charge depends on usage:
-
Daily users: Charge the batteries after each day’s use for 8–14 hours.
-
Occasional users: Charge twice a week for 8–14 hours to maintain battery health.
-
Do not exceed 14 hours of continuous charging to avoid overcharging.
Following these guidelines ensures your mobility scooter or power chair maintains peak performance and extends battery life.
