  1. I'm sure this one has come up a bunch of times.....

    I got some NiCad and NiMH battery powered toys over christmas. Now the
    NiMH is propriatary, so there's not much I can do about that. But the
    NiCad ones are just 3 AAs bundled together.

    So.... I need to get a charger for these. What I'm looking for is a good
    quality charger that won't overcharge, in other words, something more than
    the AC transformer, a diode, a capacitor, and a couple of resistors.
    (That's what the factory-provided charger consists of.)

    Ideally, I'd like to have a charger that runs off car power (12-14VDC) and
    where the batteries can be stored (or forgotten) in the charger. I know
    that's not ideal, but this is for a mobile use, and it's likely that these
    batteries won't get the personal attention that the cheap chargers
    require.

    So, to recap, a charger that charges batteries, then, when full, shuts off
    and won't drain the batteries.

    I've fished around the web, but all I find are grandiose claims like
    http://www.thomas-distributing.com/maha-mh-c204f.htm; I'm never certain
    what I'm buying. Any reputable charger manufacturers out there? Any
    places that specialize in chargers?

    Thanks,
