Features of electric wheelchair batteries


Lithium batteries or lead acid gel / AGM batteries?

The first thing to note is that each electric wheelchair has its own batteries, so the wheelchair user is not trained or cannot decide on his own to change from lithium batteries to lead acid or vice versa. Having that said, let's look at the features, advantages, and disadvantages of lithium batteries, gel batteries, or AGM batteries for an electric wheelchair .


Advantages of lithium mobility scooter batteries

  • Usable energy
  • Charging efficiency
  • Loading times
  • Weight
  • Charging cycles

Gel batteries or AGM batteries for electric wheelchairs? Which one is better to buy?

Once we know that our electric wheelchair uses lead acid batteries, now we will see which one can be more convenient for us. Compared to what happens between gel or AGM with lithium, there are fewer differences between them here.


Gel battery for mobility scooter

  • Characteristics:
  • Sealed
  • Hermetic
  • Maintenance free
  • With immobile electrolytes.


What do you mean by immobile electrolytes? Well, sulfuric acid is presented in gel format by adding a special silica.

AGM battery for mobility scooter

AGM is the acronym for Absorbed Glass Mat. They are also airtight, sealed, maintenance free, and immobile electrolyte. AGM is more resistant to deep loads and is generally cheaper.

How long do the batteries in a wheelchair last?

Although a lead acid battery has a pre-ordered cycle life, its duration will always depend on different factors such as:

  • Room temperature
  • Frequency of use
  • Discharge depth
  • Duration and frequency of charging time
  • Storage temperature.


As we have already said before, and as with most batteries for scooters, wheelchairs that mount lead acid batteries always mount a pair of 12 volt batteries, giving an output of 24 volts . It is always recommended to change and mount these batteries in pairs and not independently of each other. The power of these batteries will also be specified in each battery in units of amplifier hours (Ah).
