Where do you get cordless tools reconditioned?
If they have that "burnt" smell they are toast or soon to be. I do not think it would be cost effective to have them rebuilt.
If it is just lack of power make sure your battery packs are good. If those are bad you can rebuild them or have them rebuilt cheaper than buying new. I rebuild my own battery packs, not that hard. There are sites on the web explaining how to do it. Just do not go to a major battery suppler to purchase your batteries as they will tell you you can't do it without a 4 thousand dollar spot welder (not true).
If you have burnt out three of them I would highly recommend going to more of a contractor grade cordless.
