Lithium-ion or tightly closed lead-acid battery (SLA) batteries are frequently used in electric wheelchairs. SLA batteries are more affordable than lithium-ion batteries, but they also last less time and have a lower energy density. Longer battery life is possible with lithium-ion batteries since they are lighter, last longer, and have a higher energy density.

The user’s weight may have an impact on the battery life of an electric wheelchair. The battery may be put under more stress from heavier individuals which could reduce its functioning time. For you to ensure the best battery performance, it’s crucial to take seriously the weight capacity recommended by the wheelchair’s manufacturer.

The manner of operation and frequency of use of the electric wheelchair both impact battery life. Battery drain can occur rapidly during extended usage of power-hungry features like seat elevation or tilt controls or continuous operation at higher speeds. However, frequent usage or safe driving practises can help the battery last longer.

The battery’s capacity, which is often measured in ampere-hours (Ah), reveals how much charge it can carry. Batteries with more capacity typically have longer running durations. If extending battery life is a top priority, it’s crucial to check the battery capacity indicated by the wheelchair manufacturer and take into account potential for higher-capacity batteries that could be available.
