How to Replace the Battery in a Mobility Scooter? (The RIGHT Way)

Mobility scooters have become easier to use in recent years. But, as with all technology, proper MAINTENANCE is the key to its longevity.

A mobility scooter runs off rechargeable batteries. Those batteries power everything from the motor to the seat and lights.

Over time, the battery will degrade and lose its ability to hold a charge.

But knowing how to replace the batteries in a mobility scooter on your own could keep you from losing your independence while it is out of commission.

If your mobility scooter keeps beeping, the problem could be as simple as a dead battery. Check your battery indicator to see if it indicates a low battery.

How Does a Mobility Scooter Work?

When a person sits down on a mobility scooter, the seat makes contact with the batteries, powering on the device. You then engage the motor, ensure the brake is not on, and go.

You are free to move about for an hour before needing to be charged again.

Depending on a few factors, the batteries in your mobility scooter should last for two to three years. At some point, they will have to be changed.

If you are uncomfortable doing this yourself, you can get a friend or relative to try. Or you can call a technician.

But if you want to try, here are some steps to help you.

How to Replace the Batteries in a Mobility Scooter

If you notice that your mobility scooter has become sluggish or will not hold a charge anymore, it is time to change the batteries.

If your scooter is for indoor use, you will need two 12-volt batteries. Be sure you get the same kind you are replacing. 

1. Turn off the scooter’s power and disconnect the joystick

You should find a wire leading from the joystick to the battery that will disconnect easily.

2. Remove the seat and the base cover

The seat is different on most models, but it should come off by removing three or four small bolts.

The base cover is underneath it and is the part that connects with the batteries. You will see them once you have removed them.

3. Disconnect the battery cables and remove the batteries

Each battery will have a positive and negative cable attached to it. Take the cables from each battery and replace them with the new batteries simultaneously.

That will prevent you from getting confused and connecting your new batteries to the wrong wires.

4. Replace the base cover and the seat

Be sure you bolt the seat down securely.

5. Reconnect the joystick and charge the new batteries

Your new batteries should be charged before you use them for the first time.

How Can I Extend the Life of My Batteries?

The batteries in your mobility scooter could last for years, depending on how well you take care of them.

If you take a few extra steps, you could extend the life of your batteries and keep you from worrying about them for a long time.

1. Get the Best Batteries

Most mobility scooters use lead-acid batteries. There are two kinds of these, absorbent glass mat and gel.

The absorbent glass mat is cheaper, but the gel will last longer.

2. Charge it Right Away

After you use your scooter, plug it in. Always store your scooter with a full battery.

If you use it a lot throughout the day, it will affect its life. But keeping it fully charged will give you an advantage.

3. Store it Correctly

12-volt batteries do not last as long if exposed to intense heat, bitter cold, or a damp environment.

Keeping your mobility scooter in a cool, dry place will help you keep it going for a long time. Do not store your scooter in the garage.


What Is the Battery Life of a Mobility Scooter?

Depending on how often batteries are used, they can last from 18 months to three years. Manufacturers typically offer warranties of six months or one year.

What Is the Battery Range of a Mobility Scooter?

Mobility scooters can travel between 10 and 50 miles on a single battery charge. A battery capacity meter shows how many more miles you can travel before charging.

If you are allowed to drive on public roads with your mobility scooter, fully charge the battery before leaving for a longer distance.

A battery must typically be charged for at least six to eight hours. You must charge the battery daily if you use your device a lot.

The Bottom Line

Your mobility scooter is designed to help you keep as much independence in your life as possible.

As with any piece of machinery, some maintenance is required. Yes, it’s a valuable device! You probably want it to last a long time. It can cost a few grand, but there is also a way to apply for a free mobility scooter.

By following these simple steps, you can prolong the life of your scooter and its batteries. That will be a great way to help keep yourself in a better quality of life and less dependent on others when something needs to be done.
