The purchase of NiMH batteries like these saves you money, since you won't need to buy endless supplies of non-rechargeable alkaline batteries.

The newest PowerEx AAA Imedion rechargeable batteries feature a unique extremely low discharge design. Unlike ordinary NiMH rechargeables, which will lose a significant amount of their charge within just weeks, the unique chemistry of Powerex's IMEDION batteries allows them to retain up to 85% of their charge after a whole year of storage. Powerex rechargeble AA batteries are a favorite among professional photographers, with the highest rated "True Capacity" in the marketplace. These new IMEDION batteries are no exception and with their 950mAh "True Capacity" rating, will outperform comparably rated batteries. With their unique low self-discharge design, IMEDION batteries will actually provide longer battery life than regular NiMH rechargeable batteries of a much higher capacity rating in any device that is used intermittently over a period of time.
