How to reset a Ryobi battery

Twice I have experienced Ryobi Lithium batteries going dead. They refuse to accept a new charge from the Ryobi charger. In my case, we’re talking about the 18v batteries for a weed-whacker/leaf-blower. My method is different than all the others, so read on to see if this interests you.

I found some remedies online which did not work (plugging and unplugging the battery for 30 minutes) Are you serious? That’s not going to work for me. What does work, is warming up the battery to improve its efficiency, and then beginning a charge cycle.

Perform these steps:

To reset the Ryobi battery

Total Time: 15 minutes

  1. Turn on your oven and set it to 150 degrees


  2. Place the battery in the oven

  3. Wait for 10 to 15 minutes

  4. Remove the battery from the oven and place it in the Ryobi charger

    In my case, this is all that was needed to get the charging process going.

You might also try the following steps to troubleshoot the issue:

  1. Make sure that the battery is properly installed in the charger and that the charger is plugged in and turned on.
  2. Check the battery for any visible damage, such as swelling or leaking. If you find any damage, do not attempt to charge the battery.
  3. Check the battery terminals for any dirt or debris, and clean them if necessary.
  4. Try charging the battery with a different charger, if possible.

If these steps do not resolve the issue, the battery may be damaged or faulty and may need to be replaced.

Good luck with this tip! Hope it works for you as it did for me.
