PowerGenix 4 Pack AA 1.6v High Voltage Nickel Zinc Rechargeable cells 2500 mWa
From the Manufacturer
PowerGenix 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.
NOTE: These batteries cannot be recharged in a standard NiMh recharger. Please use a PowerGenix or other Nickel Zinc charger.
