Radio Shack 1.2v 1800mAh Nickel-Metal Hydride, and some generic charger I got for free with it. Its a pretty shitty charger, and you have to be careful that it doesnt overcharge the batteries, but it does work, and all up these batteries have saved me lots of money.
well I have a 3 hour charger that charges both NiCd and NiHM or whatnot, It is so much more smarter then going out and buying batteries. I still dont see why many people dont invest in rechargables
