    I have a Black and Decker weedwacker that takes 8 volt batteries. The
    battery charger has gone out on it recently. I tried hooking it the batteries to a solar
    car battery charger with an adapter kit I bought at Harbor Freight. I also
    have a 12 Volt Car Battery Drip Charger. I'm using alligator clips to go to
    the correct terminals, but there is also the option of going into leads that
    go to the mount which fits over the batteries. The wall wart part I figure where
    all the electronics is, but I may be wrong about that.

    I was hoping to get some thoughts on this. I know the drip charger would
    not be save to leave on for a long time.

    hi there

    well to offer decent help, it would help if we knew what type of batteries are in the drill
    different rechargeable types have different charging requirements and plugging any
    normal type of plugpack across the battery pack can kill the batteries and possibly
    cause an explosion or fire. At the very least, they are likely to seriously overheat
