Milwaukee battery recycling

I have a few failed Milwaukee batteries.  Does anybody have any experience with a remanufacturer who re-cells the batteries?

I don't have Milwaukee stuff, but I've used a place in Toledo, OH called Dyna Battery for a Snap-On battery.  Worked out great, as they found when they pulled the battery apart that it had two "dummy cells" in it.  They replaced those with actual cells, thereby "hot-rodding" my battery.  Worked well, so I had them do my other battery.  You can also buy kits to rebuild them yourself on Amazon and Ebay.

Awesome advice, thanks!

I bought cells off Amazon and re-celled my own batteries.  Easy to do with a solder gun.

How do you know the quality of the Amazon batteries?

My friend  imported misc stuff from China and the amp hours on most batteries were pumped up , often by 50 percent.

The one I did is keeping up enough with an original Milwaukee, such that I cannot tell which one is which.  YMMV.

How can I figure out what cells my battery has?

Take it apart or look online.  Chances are very high they are 18650s

Yep!  I used the YouTubes and it looks relatively easy to do.  Plus, I can upgrayedd my cells for more powah!
