If your Ryobi charger has stopped working, the most common culprit is a battery that has gone into sleep mode. This can happen when the battery has been completely drained and needs a little boost to revive itself. Here’s how to fix it:
The Sleep Mode Fix
Slot the defective battery into the charger for a few seconds
Remove the battery before the lights flash
Repeat this process (up to 30 minutes) until the battery has enough charge to ‘revive’ itself and start charging normally
If this doesn’t work, there are a few other troubleshooting steps you can try:
Other Troubleshooting Tips
Check the battery terminals for dirt or corrosion and clean if necessary
Ensure the battery is making good contact with the charger
Use a multimeter to check the voltage of the battery and charger
Try charging the battery in a different temperature range (41°F to 113°F is ideal)
If all else fails, the battery may need to be replaced under warranty
If you’ve tried these fixes and your Ryobi charger still isn’t working, it’s best to take it to a repair shop for further diagnosis. With a little troubleshooting, you should be able to get your Ryobi tools back up and running in no time.
