Lithium-ion Wheelchair Battery

Why lithium battery is better for electric wheelchair?

The popularity of electric wheelchairs and mobility scooters stems from their ability to allow both seniors and disabled individuals alike to experience a degree of independence and ease of transport that was not possible before. Making them can give you an extra boost of confidence and increased well-being.

As much as it is a revolutionary innovation, motorized wheelchairs and scooters are not immune to malfunctions and are dependent on batteries. These batteries provide the power needed to keep your PMA—that is, a device that allows mobility-impaired people to travel independently—operating smoothly.

When choosing the best batteries for your personal mobility device, you should consider both lithium-ion and lead acid.


Due to their high energy density, lithium batteries have become a preferred power source for many portable electronic devices.


If you need to replace your battery, it may be difficult to find a lithium-based one (such as those used in personal mobility aids) compared with the more common sealed lead-acid batteries. Given that lithium batteries are designed specifically for your motorized wheelchair or mobility scooter, finding a ready-made replacement can be challenging. You would have to take the battery back to the store where you purchased it and ask that they order a custom replacement for you.

Unlike traditional lead-acid batteries, which are often used to power cars, the sealed lead acids typically found in personal mobility aids have been installed in various devices like electric bicycles and backup power systems. Sealed lead-acid batteries are so common and useful that you’ll find them everywhere in Singapore—from major retailers to local markets. If one of these batteries fails, you can get a new one almost immediately from any auto parts store or licensed dealer.


For many consumers, battery efficiency is an important factor in deciding which electronic device to buy.

Lithium batteries typically perform better than sealed lead-acid ones, as they have a higher efficiency rating. This translates to a longer traveling distance for the same capacity rating.

A lithium battery provides you with a more efficient wheelchair, consuming less energy and producing more power than its competitors. 


Lithium batteries are around 55% lighter than sealed lead-acid ones. If you travel in your car often, you should consider looking for a lightweight portable device—equipped with a lithium battery—to use during these trips. 

This will make it easier for you to load your PMA device onto your car.


Another important factor in buying a new battery is longevity. In this respect, lithium batteries last longer than sealed lead-acid ones.


Lithium batteries power electric wheelchairs and offer a longer life span than other types of batteries.
