Rechargeable: Difference between revisions

This is a new (introduced in 2008) battery chemistry with an uncertain future. 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 [[battery 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. The jury is still out on these cells, with some people finding the performance of the cells to be inconsistent. In February of 2011, Powergenix said they would no longer make AA batteries and chargers and instead focus on industrial uses of larger NiZn batteries.
