Check The Fuse

Before you jump to any conclusions, it’s important to check your scooter’s fuse. If your battery isn’t charging, or won’t charge fully, there could be a problem with the fuse.

You can do so by accessing your mobility scooter’s fuse panel. Just look under your seat for an access panel that flips up.

Once you have access to your scooter’s electrical components, try unplugging and removing every fuse from its position; check for corrosion or dirt and place them back in their positions when you’re done.

Remove/Clean The Top Cap

There is a metal plate that holds down your battery. Remove it, and you should be able to remove and clean your mobility scooter’s battery contacts.

The top cap should be held on by several screws; remove them, then slide off the battery cover.

If you don’t know how to open it, consult an owner’s manual for instructions. Use a wire brush to clean off any corrosion on your battery’s terminals before reattaching it.

Once you’ve cleaned off all of the corrosion from both sides of each terminal, take a new piece of sandpaper and smooth out any rough areas left by that brush.

Note: Do not use steel wool or any other abrasive material when cleaning your terminal posts; steel wool will damage your positive terminal and make charging impossible!

Check All Wires

In most instances, if you have a problem with your mobility scooter not charging, it can often be traced back to one or more of three wires.

The white wire, red wire, and black wire are all important and should be checked thoroughly when diagnosing an issue like a mobility scooter battery not charging.

Each of these wires carries power from either your home’s electrical outlet or a charging station for your electric wheelchair. Make sure each of these wires is in good condition and tightly wound around their respective posts at both ends.

Most problems will occur because of broken connections on one end of one or more of these three wires. If that is your case then you should buy new cables and splice them on before plugging in again.

Unplug The Charger And Start Over

Once you’ve charged your mobility scooter battery for a few hours, unplug it from charging and let it cool down for about an hour. Plug it back in and let it charge again.

Do that until your mobility scooter’s battery is fully charged. Keep in mind, that while some of these instructions may seem complex, you shouldn’t need to do all of them if your battery will still take a charge after a few hours on its own.

However, if that doesn’t work, keep trying each method one at a time until you find something that works to get your mobility scooter going again!

Use a Voltage Tester

One of the easiest ways to troubleshoot a dead battery is to use a voltage tester. This tool will quickly tell you if your scooter’s battery has enough juice left in it to run or if it needs a full charge before it can operate.

The process is simple; attach one end of your voltage tester to one terminal on your mobility scooter and then attach the other end to another terminal on your mobility scooter.

If your meter indicates that there’s still power inside, you should be able to give it a full charge. If not, however, then all you have left is to replace that bad battery altogether.

Try Another Wall Outlet

When you initially purchased your scooter, you should have received a manual. In addition to having useful information such as maintenance requirements and warranty information, it will also explain how to charge your scooter’s battery.

Read through all of it and make sure that everything is being done correctly before continuing. There may be further troubleshooting instructions for battery charging problems if applicable.

If not, then continue with section nine below which will cover troubleshooting advice specific to mobility scooters specifically.

Following is what might have happened. The charger circuitry (transformer, rectifier diodes, capacitors) has gone bad.

A power surge and/or a lightning strike nearby may have caused damage to it and you are now getting nothing out of it.

The fault can also be elsewhere in your supply line. Assuming there is nothing wrong with your battery, simply replace your charger with a new one and see if that fixes it.

If not, you’ll have to check further up in your supply line from where it plugs into the wall socket as I mentioned above to find whatever’s causing you the problem.
