A few years ago, I seem to recall that there was a hack that let you reset old Ryobi batteries so that they would accept a charge again. I have a couple batteries (18-24v) that will no longer charge and give you an error message on the charger. I'd like to try to bring them back if possible before shitcanning them. Anyone know the procedure to do so?

Put the batteries in an Instant Pot, fill with nails and gasoline, push SOUP.

You can replace the battery pack in the battery.

According to this guy, unplugging and replugging the charger while the battery is inserted will eventually flip the battery to fast charge.

Shit can because they're dead or shit can because they're ryobi
Yea.... are they lithium ion? Or old nicads? Because both have a certain life cycle and are comprised of multiple cells, if even half of a cell I bad the entire battery is junk

They're only 2-3 years old and haven't been used a lot. Should be lithium but not 100% sure

Another question is are you sure the charger is working. Do you have a multi meter?

I have other batteries that it charges just fine. It's a smart charger so it won't even work if it reads the battery as "bad"
Ahhh, ok, yea you might want to try and put the battery in the charger then plug it in and out a few times. Other wise it might be a loss, the charger is probably detecting a bad cell, it happens, I had 3 12vt dewalt batteries go bad that way

Haven't tried it yet
But I have one that stopped charging after about 6 months
Worth a try I guess
There are several other vids though

If you know the size of the cells, you can order them on Alibaba. Then get a small industrial spot welder.

My batt has security torx screws
I don't have bits for those
Maybe Harbor Freight has them
Looks like a T-15 with a post

Stop being such a cheap cocksucker and buy a new battery.
