Rebuilding/fixing dead power tool batteries

[P51Boilermaker]

I know I'm not the only one with dead power tool batteries that won't hold a charge anymore. I found this instructable on how to replace the cells! I haven't done it yet but with the high cost of replacement batteries it's worth a try.

There are some videos on you tube also on how to do this may give it a try on some i have.

Yeah, I've got some old ones that I haven't recycled or had the money to replace yet. Hopefully it's not too difficult

I will be giving it a try after the hustle and bustle of the holidays. Just too busy with family and friends visiting right now to even think abut doing it.

Rebuilding a Ryobi 18v battery was yesterday's project for me. Worked out fine and no surprises. That said, I don't think I'll be doing it again, unless the replacement cells get significantly cheaper. It's a bit labor intensive and I didn't save that much over the occasional sale price at Home Depot.
