Changing the battery on an electric wheelchair

Deciding which battery you want may seem complicated at first, but a few simple steps will enable you to select the correct one for your machine.

Changing the battery on an electric wheelchair need not be complicated. All scooter / electric wheelchair batteries are 12 volt and are usually fitted in pairs giving a 24 volt output.

It is recommended that when replacing batteries they are fitted in pairs.

The power output is marked in amp hours (Ah) on the side of the battery E.g. 12volt 35amp. The amp hour rate may vary slightly from different manufacturers for a similar size battery, therefore the critical thing is the physical size of the battery.

Here’s our quick guide

 12ah upto 15ah

Upgrade from a 12ah to a 15ah battery.

12V 15Ah Sealed Lead Acid Battery. This battery is suitable to be fitted to any brand of mobility scooter.Dimensions: (L) 151mm x (W) 99mm x (H) 100mm

This battery has the same physical dimensions as a 12Ah battery. This battery will provide a greater range than the standard 12Ah on a single charge.  These batteries are suitable for electric bikes such as Powabykes.  This battery comes with 1 years warranty against manufacturing defect. We recommend that batteries are charged on a regular basis even if the powerchair/scooter is not being used.

Upgrade from a 40ah to a 50ah battery.

12V 50Ah Sealed Lead Acid Battery. This battery is suitable to be fitted to any brand of mobility scooter.  Dimensions: (L) 195mm x (W) 165mm x (H) 180mm

Upgrade to Gel Batteries

Recommended for daily mobility scooter and powerchair users, GEL mobility batteries are the ultimate battery, offering unrivalled performance.

Each of the differing types of mobility scooter batteries has its advantages depending on what you are looking for from the battery; but the general rule is that the more you pay – the longer you can expect the battery to last.

We recommend Gel batteries for all Powerchair users. Mobility scooter batteries and wheelchair batteries can be either sealed lead-acid or Gel depending on what performance you are looking for.

We always recommend replacing mobility scooter batteries and wheelchair batteries in pairs.
