The chemistry of Ni-MH brought an evolutionary change in the Energizer battery industry introducing batteries with cycle life (reuse after charging). Typically, NiMH batteries can be recharged hundreds of times, potentially allowing them to be equivalent to hundreds of alkaline batteries in total service over their lifetime. By using Energizer Recharge batteries for digital cameras, handheld GPS devices, wireless gaming systems, toys, you name it – you can experience the convenience and value of innovative, industry-leading rechargeable battery technology. Energizer AA Rechargeable NiMH Batteries(2300mAh) is one of the dominating items presently on demand. • Features:  Typically, can be recharged hundreds of times.  NiMH batteries provide approximately 75% of the capacity of alkaline AA batteries at low drain rates.  Efficient at high rate discharges.  Typical expectancy life is 2 to 5 years.  Operates well at a wide range of temperatures: Charging 0° C to 50° C, Discharging 0° C to 50° C  Associated Battery Sizes: 1.2H2, 1.2K2, 10320, AA, BK-3HCCE, BK-3MCCE, DC1500, DX1500, HR-3UTGB, HR-3UWXB, HR6, KR6, LD715, NH15, NM715, PL715 • Specifications:  Classification: Rechargeable  Chemical System: Nickel-Metal Hydride (NiMH)  Designation: ANSI-1.2H2  Nominal Voltage: 1.2 Volts  Rated Capacity: 2300 mAh at 21°C (70°F)  Typical Weight: 30.0 grams (1.1 oz.)  Typical Volume: 8.3 cubic centimeters (0.5 cubic inch)  Terminals: Flat Contact  Jacket: Plastic
