Maybe I should try a seperate thread (or the battery forums), but I've got a question you might be able to answer:

I just ordered the 3500mAh, 12V NiMH battery from batteryspace with what I *thought* was a smart charger, but it turns out it wasn't. It's just a 400ma wall-wart.

I do, however, have a DeWalt drill charger suitable for modding. I know it'll handle that voltage/capacity, but it's designed for NiCad. Is it safer to use the dumb charger, or a charger designed for NiCad (that's using delta-V, I suppose)?
