Now, comparing these two electric wheelchair battery types is a bit hard. Because they both have their merits and demerits, it all comes down to what you consider a major advantage and major disadvantage. Let’s check out both types.

  • AGM: These batteries come in at a cheaper cost. And they produce fewer cycles, so they don’t last very long. Due to that, it’s a good match for people who use the wheelchair occasionally. Also, the fact that the price is so low is great for saving up money and have good performance at the same time.
  • GEL: Anyone who needs to use their wheelchair daily has no option but this one. It comes with more cycles, and due to that, it can last a lot longer. Because of all the good stuff, it features this is the best wheelchair battery you can get for yourself. However, good things come at a good price. So, you have to pay a good amount of money to get this one.

You can very easily test the battery of a power wheelchair or a mobility scooter. All you need is a voltmeter. So, how do you do it?

After you do that, take the two probes of the voltmeter and connect them to the charging ports. Connect one on the left port and the other one on the right port. Keep in mind you won’t use the middle port for any purpose here.

Once you connect the probes, you should see at least 24 Volts on the voltmeter’s display. Given that the battery is fully charged, it can go higher than that. But if it’s lower, then there are some issues with your battery. And that’s how you test it.
