1000MAH AAA NiMH Rechargeable Battery

If you want to recharge your batteries,use Nickel-Metal Hydride (NiMH). These have much higher capacity than NiCd's and don't suffer from memory effect. Using NiMH rechargeable batteries instead of single-use alkaline batteries can save you a lot of money as well. NiMH batteries were developed especially to meet the higher energy demands of today's electronic devices and are more powerful and more environmentally friendly than standard alkaline or NiCad batteries.
