Ok, many of you here are going to think I have lost my mind and maybe I have but I have been reading several articles tonight about how to bring my old dead rechargeable Ni cad (cordless drill) battery packs back to life. I have read everything from smacking them hard with a block of wood to "zapping" them with higher voltages to placing them in the freezer. The theory is that the cells have produced "crystals" within themselves and therefore short themselves out. By zapping them you break down these crystals and the cells will then again take a charge and continue to work again. The idea is to apply twice the voltage for just a few seconds then check the voltage with a meter until it responds with about 2 volts over the rating of the pack. Has anyone ever tried this?
I read all this here on the INTERNET so it MUST be true. Right?
Yes I know the battery will not be covered under warranty anymore and yes I understand that they can overheat and explode. So I am not suggesting to anyone to try it. I'm simply thinking of trying this for myself.
Here is a link to one of the places I was reading. http://ysuusy.com/easybatteryfix.html
