Ryobi 40 Volt Battery Not Working? How to Fix by Resetting Battery (Blinking Light/Charging Issue)

In this video, DIYNate shows a shortened version of how he was able to reset his 40 Volt Ryobi battery and get it to come back to life. This version of the video skips the first battery attempt and focuses on the successful battery reset process (both batteries were reset, but only 1 took a charge).

In this video, DIYNate shares his trick to resetting a Ryobi 40V battery and how he took the battery apart, used an insulated paper clip (wrapped with electrical tape), and was able to reset the battery to once again be able to charge. While he tried this with two batteries, the first one did reset but was not able to take a charge. The second battery was a fully successful attempt - it did reset and take a charge, and DIYNate now uses this battery around the house on a regular basis.
The steps include:
1. Confirm the blinking light issue on both battery and charger (blinking red and green on charger; blinking all lights on battery when button is pushed)
2. Remove the T10H Security Screws (note, you may void the warranty by opening up the batteries); also, use caution / warning - electricity is dangerous and so are batteries. Video for entertainment purposes only, and DIYNate assumes no liability.
3. Peel back the sticker that separates both halves of the battery, or cut a line through the sticker enabling the top part of the battery to separate from the bottom part.
4. Remove the top cover and find the battery reset holes (2 small ports next to each other about halfway along the battery length toward one side).
5. Use an insulated wire or wrapped paperclip to depress the two reset ports; make sure to protect / insulate / ground yourself just in case.
6. Light flashes when the reset ports are both pushed in at the same time indicating the battery has been reset.
7. Put the battery back together with the T10H security screws (you may only want to put 2 screws in initially in case the fix doesn't work and you need to access again).
8. Attempt to charge the battery again; if you are lucky / fortunate, it will charge and you will be able to use your battery again.
9. If you did not finish putting the security screws in, finish sealing the battery with the remaining security screws.
Note that if your battery is under warranty, you are likely better off partnering with Ryobi or The Home Depot for repair / service vs. doing this, as it may void your warranty. However, if your batteries are beyond warranty, this hack / trick may very well keep your batteries alive for a longer period of time. (Reminder, DIYNate assumes no liability).
Good luck - hope this repair works well for you! Nothing like dealing with high dollar batteries that are failing or no longer working correctly.

My Ryobi 4ah and 6ah dont have those reset spots on them! Idk what to do, every video shows this exact step.

Hey Trevor - sorry for my slow response and thanks for being the first to comment on the video. Couple thoughts as I didn’t / don’t know the answer (yet) to your situation. 1. It is possible, Ryobi may have changed the layout of their boards vs the ones in my video. Want to share what model / year your batteries are? We may get some other comments. 2. Wondering if you look very closely if you see a 1 hole reset button or something else that looks like it may work. May be a different style reset.
I’ll keep my eyes out for other comments where people aren’t seeing the reset holes - I did review a few other very popular Ryobi reset videos but very few had this issue in the comments and no one seemed to have an answer for a different type of reset. Couple other reset tricks mentioned were putting it on and off the charger multiple times, cleaning the contacts and even putting it in a freezer. Not sure about those.
Good luck and thanks again for commenting!
