The report describes work performed toward the development of two separate zincair battery systems conforming to the Electronics Command Technical Requirements SCL 6895 and SCL 6896. SCL 6895 calls for the development of a 60 watt- 720 watt-hour zincair battery with the capability of voltage selection in the range of 8, 16, 24 and 32 volts. Technical Specification SCL 6896 required the design, fabrication and evaluation of zincair batteries to power radio sets ANPRC-41 and ANPRC-47. The design target weight of this latter system is 10 pounds within the physical dimensions of length-11-58 in., width-4-316 in. and height-7-34 in. Voltage regulation was specified as 22 to 28 volts. The two battery systems were designed, fabricated and evaluated. Tests performed indicated that the 24 volt, 25 ampere-hour system can be discharged repeatedly more than 20 times against the ANPRC-47 transceiver and still deliver rated capacity. Mechanical recharge of the system was demonstrated and was performed in less than the 10 minute requirement. Life studies were performed at LML and indicate that a battery life in excess of 50 recharges should be obtainable at the present time. The 60 watt- 720 watt-hour system was also evaluated. The system has delivered in excess of one kilowatt-hour at the 60 watt power level. Author
