Everything You Need to Know About Electric Wheelchair Batteries

Electric wheelchairs have become a vital tool for individuals with mobility issues, providing them with independence and freedom. One of the most critical components of these wheelchairs is the battery. Battery life, performance, and maintenance significantly impact the overall functionality of the wheelchair and the user's experience.

In this blog post, we will cover everything you need to know about electric wheelchair batteries. We will delve into the following topics:

1. How Long Do Electric Wheelchair Batteries Last?

The lifespan of electric wheelchair batteries depends on the battery type, frequency of use, and charging habits. There are two main types of batteries available in the market:

  • Lead Acid Batteries: They are an older type of battery and have a lifespan of 1-3 years. Lead acid batteries are cheaper but heavier and have less energy density.
  • Lithium Ion Batteries: They are a newer type of battery and have a lifespan of 2-5 years. Lithium-ion batteries are more expensive but lighter and have more energy density.

Other factors affecting battery life include:

  • Frequency of use: The more often it is used, the shorter the lifespan.
  • Extreme temperatures: It is important to keep batteries away from extreme temperatures.
  • Deep discharge: Batteries should be charged before they discharge below 20%.
  • Incorrect charging: Using the correct charger and method is crucial.

2. How to Charge Electric Wheelchair Batteries?

To charge the batteries, follow these steps:

  1. Plug the charger into an outlet.
  2. Connect the charger to the battery port on your wheelchair.
  3. Wait for the batteries to fully charge.
  4. Disconnect the charger from the outlet and your wheelchair.

The time it takes for the batteries to fully charge depends on the battery type and capacity. Once the charging process is complete, remember to disconnect the charger from the outlet and your wheelchair. Overcharging can shorten the battery life.

3. What to Do to Extend Battery Life?

You can follow these steps to extend the battery life:

  • Choose the right battery type: Select a battery type that suits your usage frequency and needs.
  • Keep batteries away from extreme temperatures: Avoid storing or using batteries in extremely hot or cold environments.
  • Charge batteries before they discharge below 20%: Charge batteries regularly and avoid letting them discharge below 20%.
  • Do not charge batteries to 100%: Charging batteries to 80-90% can extend their lifespan.
  • Use the correct charger: Use a charger specifically designed for the batteries.
  • Check batteries regularly: Inspect batteries periodically for any damage or deform

4. What Can I Do to Conserve Battery Power While Using My Electric Wheelchair?

You can follow these steps to conserve battery power:

  • Go downhill whenever possible: You can save motor power when going downhill.
  • Adjust motor power when going uphill: You can conserve battery power by adjusting the motor power required when going uphill.
  • Avoid unnecessary use of your wheelchair: For short distances, you can go manually instead of using your wheelchair.
  • Use a driving mode that requires less power: If your wheelchair has multiple driving modes, you can choose a mode that requires less power.
  • Check tire pressure: If the tire pressure is correct, you can move with less power consumption.
  • Do not add weight: Adding unnecessary weight to your wheelchair will shorten battery life.
  • Have batteries serviced regularly: By having your batteries serviced regularly by an authorized service center, you can extend their lifespan.

Additional Information:

  • If you experience any problems with your batteries, contact the manufacturer or an authorized service center.
  • You can participate in special programs to recycle batteries without harming the environment.


Electric wheelchair batteries are one of the most critical components of the wheelchair. By following the necessary steps to extend battery life and conserve battery power, you can enhance the performance and lifespan of your wheelchair.
