3、ration has authorized the use of this commercial item description (CID) as a replacement for MIL-B-23272B and MIL-B-23272/1B, which are canceled. 1. SCOPE. This CID covers the requirements for nickel-cadmium storage batteries primarily for service in military vehicles, starting of missile ground pow

4、er equipment, radio operation, and as a source of electrical energy for operating vehicular accessories control mechanisms. The nickel-cadmium batteries have a wide tolerance to temperature extremes. They require less derating at low temperatures than lead acid units. Since the specific gravity of t

5、he battery electrolyte does not change with the state of charge, they are not susceptible to freezing once a discharge is underway. Nickel-cadmium batteries can operate from plus 200 degrees Fahrenheit (F) to minus 65F without damage or without the threat of freezing. 1.1 Classification. Batteries s

6、hall be of the following types, as specified (see 5.2): Type I - 2HNC 12-Volt, 35-ampere-hour capacity. Type II - 6TNC 12-Volt, 70-ampere-hour capacity. 2. Salient characteristics. 2.1 Material. Material shall be as specified herein. The use of recovered material made in compliance with regulatory r
