Here are two options to revive your wheelchair again;
Before optioning the first option you have to determine whether you need to invest in a new wheelchair battery or not. So, you have to assess the battery conditions. If you see the battery is old enough and has completed its life cycle. If you see swollen or bloated signs on the external surface of the battery.
The second option requires a bit more effort to revive your dying battery. This approach can be effective if your battery suddenly loses power or if your wheelchair has been sitting unused for weeks or months, leaving the battery completely drained. In these cases, simply plugging in the charger may not be enough to get it charging again.
Below are a few methods you can use to revive the dead battery of an electric chair.
If your wheelchair battery has died and your charger isn’t working, don’t worry—there’s a simple way to get things going again. Follow the below methods to revive your wheelchair battery and get back on the move.
What You’ll Need:
When a wheelchair battery is completely drained, the regular charger often won’t recognize it, leaving you stuck. The key is to provide a small initial charge to “wake up” the battery.
To “trick” the charger into recognizing the battery, you’ll need a 12-volt charger. This can be from a kid’s ride-on toy or any similar device that provides a small, safe charge. Using wire strippers, carefully expose the metal wires at the end of the charger. Identify which wire is positive (+) and which is negative (-).
Locate the battery compartment on your wheelchair. Ensure you match the positive (+) and negative (-) terminals from the 12-volt charger to the corresponding terminals on the wheelchair battery. This step is crucial to avoid damage.
Plug in the 12-volt charger and let it charge the battery for about 5-10 minutes. This brief charge should be enough to “wake up” the battery, allowing your standard wheelchair charger to take over.
After the initial boost, disconnect the 12-volt charger and plug in your regular wheelchair charger. At this point, the charger should now recognize the battery and begin charging it fully.
Allow your wheelchair to charge fully using its regular charger. This may take several hours, depending on your model.
First, you need an automotive battery charger that has a gel or AGM battery mode. Avoid using the standard manual chargers with high amperage (e.g., 80 amps).
Set the charger to the correct mode for gel or AGM batteries. If your charger doesn’t have these settings, you should proceed with caution or opt for a charger that does.
Carefully remove the batteries from the wheelchair. Remember to note the orientation and connections.
Attach the charger’s positive (red) lead to the positive terminal of the battery and the negative (black) lead to the negative terminal.
You have to set the charger to a low amperage setting (around 6 to 12 amps) and begin the charging process. You can expect 6 to 12 hours to fully charge deeply discharged batteries.
Don’t forget to check periodically if the charger is working correctly. The charger should show a charging status or indicator light.
Once the charger indicates the battery is fully charged, disconnect it. Reinstall the batteries into the wheelchair.
Plug the wheelchair in and test its functionality. If the battery level still seems low, consider repeating the charging process or replacing the batteries.
If you discover that your wheelchair battery has reached the end of its lifecycle, it’s time to consider purchasing a replacement. However, if your electric wheelchair battery suddenly dies or your wheelchair has been unused for a few months, you might be able to revive the battery using the methods outlined in this blog.
To ensure your wheelchair battery lasts as long as possible, make sure to charge it regularly, avoid overcharging, and store it properly. Following these precautions can help extend the lifespan of your battery.
