SILVER ZINC CELLS

Tables 1 and 2 provide the nominal characteristics for several of BST's silver- zinc, high energy, rechargeable alkaline cells.  Silver-zinc cells may be used in a variety of series and parallel configurations to achieve virtually any specified voltage and energy requirement.  Cells can designed to optimize specific characteristics such as high power, high energy, cycle life, capacity, etc.
