How do you buy a better power wheelchair battery?

Batteries are the engine of every power wheelchair. If the engine stops working, then the power wheelchair turns into a heavier manual wheelchair. So many available battery types are currently in the market. But we need to discuss the things to consider before buying a power wheelchair battery.

Factors to consider before buying a power wheelchair battery.


The main thing that we aim at when buying a battery is durability and reliability. Therefore, we need to know the specifications of the different batteries that we buy. A wheelchair battery should last for an extended period.

The wheelchair user might not be capable of replacing it frequently; thus, the materials used should be of high quality. It should also hold a charge for at least the whole daytime.


New wheelchairs come with batteries that have a range of 6 to 15 AH. When buying a replacement, you need to consider buying the one with a higher configuration of 30 AH to 60 AH. This will increase the max travel distance of your wheelchair.

Charging Time

You must consider the total charging time for your battery. A wheelchair battery should not take more than 6 to 9 hours to charge fully. Wheelchair battery needs to be used throughout the day; then, it will be charged at night for effectiveness. You should always go for a battery with a short charge time.


You need to be keen on the warranty conditions of the particular battery that you want to buy. The warranty period should be reasonable, and it should not be less than one year. Some batteries and battery companies need you to bear the shipping fees when you are invoking the warranty. Shipping costs to avail of a warranty can be challenging, depending on your location.


You should never be bothered a lot by the weight of the battery. However, it should not be less than 10 pounds. For batteries with large configurations, the battery weight can exceed 25 pounds. This will add to the weight of the wheelchair; hence can it hinder folding and lifting of the wheelchair.

Dimensions Of The Battery

Before buying a replacement battery for your wheelchair, consider a battery that will fit inside the battery box of the wheelchair. This should never bother you unless you are considering buying a bigger wheelchair battery.
