CHARGING_SILVER_ZINC_CELLS

Used for initial charging and subsequent rechargings of sealed dry-charged lightweight cells developed for use in missiles, torpedoes, and space applications. Article covers procedure for filling cell with potassium hydroxide electrolyte before placing in use (cells are dry-charged at factory and have shelf life of 5 or more years in that condition). Charge current should be 7 to 10% of rated cell discharge capacity; thus, for Yardney HR-5 cell with rated discharge of 5 A, charge at 350 to 500 mA. Stop charging when cell voltage reaches 2.05V.If used only for battery charging, large filter caacitor can be omitted.-S.Kelly, Will Silver-Zinc Replace the Nicad?, 73 Magazine, Holiday issue 1976, p 204-205.
