===Nickel-Zinc (NiZn) - 1.6V/cell===
===Nickel-Zinc (NiZn) - 1.6V/cell===


This is a new (2009) battery chemistry. It requires a special charger due to the higher nominal voltage of NiZn cells. They are 1.6V nominal, but are charged to 1.8V to 1.9V and are recharged at 1.5V. PowerGenix makes the batteries and chargers, claiming 2500 mWh of capacity (see [[Measures of Capacity]]). Quantaray is another company that makes NiZn AA cells. The higher voltage may make some flashlights brighter than on NiMH or Alkaline cells, but could also damage devices, especially if they use a number of AA cells in series. NiZn cells are advertised as capable of 200 full charging cycles, which is less than LSD NiMH cells.
