    Carefully check the status of the 19.2v charger and batteries.

    Long ago.......my close friend's 19.2v Craftsman charger and battery went bad. One or two cells in the battery pack went bad(shorted), and subsequently blew the thermal limiter in the charger. I replaced the bad cells and repaired the charger..........but alas more cells in the battery pack started to also fail. It's a situation of cascading cell failure in an old Ni-Cad battery pack.

    Solution.........if one cell fails......replace the whole pack.(edit: or convert to lithium batteries)

    Hope this helps......

    That helps a lot, and I appreciate the info.😎

    Well, I lucked out, and the batteries all work great. A buddy of mine had a double charger and a couple batteries that he wasn't using any more, and tossed them my way. I gave them all a good cook overnight. That hammer drill will strip skin off your hand if you're not paying attention!🤣

    Good deal!

    To be sure of a full charge.......use a digital voltmeter to measure a battery pack voltage immediately after charging. And then measure again 24 hours later.

    Also.......do NOT leave batteries on the charger permanently. Doing so will cook/kill individual 1.2 voltmeter cells within each battery pack.

    I use a separate appliance timer.......to plug the charger into.......allowing only 1 hour of charging each day.

    Hope this helps.
