One of my cordless drill NiCd battery packs couldn't hold a charge for more than five minutes anymore so it had to go. But I kept the platic case and the push connectors and wired them to a power supply! The drill (Bosch PSR 960, but the concept can easily be transferred to any model) can still be used with a good battery pack as before, but you can easily switch from cordless to corded mode depending on your needs (or if you're just to impatient to wait for that charger to finally get its job done).
The first working version is usable, but you have to accellerate with a bit of caution or it stalls. Perhaps a capacitor can mitigate this effect, and I might also add some fancy LEDs when I open it up again...
