  • Battery fix using mig welder

    Long time since I've been here. I remember reading about this somewhere and was wondering if anyone has been successful? I have a box full of DeWalt batteries and figure what the heck, if I can bring back one or two it might be worth it. I know it's not recommended and probably kinda dangerous but if someone has done it successfully why not try it.

    No matter how hard I try, I always hear about the other guy who can do it better, faster and cheaper. Sure would like to meet him someday but no one seems to be able to find him when I ask. [B]

    I'd do it just for fun to watch them melt and blow up

      Glad to see you're still around

      I know you know your way around welders and such and have more than the average gasp of electrons doing their thing. I was thinking it was'nt really smart and with two feet of snow on the ground I would have to do it in the shop. If I do try it it will be outside and I'll be sure to video it. Could be epic.

        I learned this the hard way and it cost a lot of money. Thro that **** in the dumpster and buy some new batteries, buy a couple extra and get on with it. Having all the rest of the overhead, like buying a new truck and not putting gas in etc. We own 10 welding machines and 20 trucks and not going to replace some years old well worn batteries.

          Why not just have them rebuilt? Its a fraction of the cost for new...

            Has anyone had experience with rebuilt batteries? It has been many years since I dismantled a Makita 9 Volt, it was two stacks of 1.25V c cell Ni Cad with leads soldered on
