    You say it costs $2. So where do we get the 25.6 VAC PSU for free ?

    you can use a lower voltage one and a 1$ step-up converter found on ebay.

    look around in thrift shop for an old powerpack.

    Wow, so it is a super simple "trickle charger"

    No wonder the batteries never last. Basically zero intelligence charge control.

    actually a slow charge is better for most battery, the temperature is very important too.

    sadly they are dumb charger so are very prone to overcharge.

    Quite usual, I have Skil drills and the schematic is more complex but in the end its also a battery torture device. For that reason I use an other device to charge the drill batteries.

    i included the battery cell #, but i haven't looked up the specs and since my drill still works i aint going to chop it up to know either.

    dont be fooled by the wall wart that come with those, they are AC out but are marked DC on them.
