Better alternative: mWh To detail more precisely the performance differences between batteries, the mAh rating—which is the product of current and time—must be enhanced to include voltage. As the product of current, time and voltage, the mWh rating delivers this much-needed measurement improvement. Nickel Zinc Rechargeble Battery has developed a high-energy density, high-cycle life and low-cost nickel-zinc (NiZn) battery ideal for applications that demand high discharge rate capabilities. The technology offers compelling performance advantages, most notably a 30% weight and size reduction coupled with higher power and superior low temperature discharge behavior. Two of the more prominent features of the PowerGenix NiZn battery are its small size and low internal resistance, which enables the delivery of significantly more power during periods of peak demand than a nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) battery of comparable size. Although the design and construction of the cell is similar to NiCd, the higher voltage of PowerGenix's NiZn cell results in a 25% lower cell requirement in multi-cell packages, representing significant space and cost savings. Type: nickel-zinc battery Capacity: 2500mWh Weight: ~ 24.5g Size (D x H): 14.25 x 50mm Compatible with: any device with AA Batteries such as AM3 UM3 KR6 NiCd HR6 NiMH, LR6 Alkaline, R6 carbon–zinc Battery *NOTE* : These batteries cannot be recharged in a standard NiMh recharger. Please use a Nickel Zinc charger.
