    I've done this for my propeller clock. Not charging, but transfer of power. Certainly doable, but be warned its a fairly inefficient way of transferring power.

    If you could give an idea of the battery voltage, and the current you want to charge it at, we could take it from there.

    Buy one of those $19.95 toothbrushes that you sit in the cradle to recharge, and reverse-engineer it. I have one that's been working for 10+ years..

    The toothbrush has a hole in the bottom, where sits in over a plastic post in the cradle, and recharges with no metal contacts.
