Choosing the Right Battery for Mobility Equipment

Mobility scooters and power chairs require true deep cycle batteries designed for repeated discharge and recharge. General-purpose sealed lead acid batteries, often used in standby power applications, may not perform as well in mobility applications.

Common mobility battery sizes include:

Once you’ve chosen the right battery and size, understanding how it works and how to care for it will help you get the most out of it.

What is a Battery Cycle (and Why It Matters)

A battery “cycle” refers to one full discharge and recharge of a battery. The more cycles a battery can provide, the longer it will last in real-world use. To extend battery life, avoid deep discharges – keeping the battery above 50% state of charge can help increase overall lifespan.

How to Extend the Life of your Wheelchair Batteries

Start with a fully charged battery. Recharge your battery after each use so it is ready for the next time you need it. Starting from a full charge helps improve performance and longevity.

Avoid deep discharges. The deeper you discharge a battery, the more wear it experiences. For example, regularly using only 50% of the battery capacity will help it last longer than frequently draining it close to empty.

Recharge before the battery is too low. Keeping your battery above very low charge levels will help extend its lifespan and maintain consistent performance.

Maintaining off-season storage. If your mobility equipment is not used year-round, proper storage and maintenance are important. Batteries should be kept charged and maintained during periods of inactivity. See our off-season maintenance guide for some tips.
