NICKEL-METAL HYDRIDE (NiMH)
If you want to recharge your batteries, use Nickel-Metal Hydride (NiMH). These replace obsolete NiCad rechargeables. NiMH's have much higher capacity than NiCd's and don't suffer from memory effect. 1powershop have great prices on NiMH's and carry the highest capacity D's (9-11,000 mAh). Radio Shack sells them too but they cost a little more (and their D's have less capacity). Also see our recommended chargers. NiMH's are great all-around batteries but they have a high self-discharge rate (they go dead after a few months even if you don't use them) so they're not good for things like emergency flashlights or smoke detectors.
