本航空航天标准的目的是对飞机上普遍使用的通风式可充电镍镉电池的要求进行定义。这些电池可作为发动机起动的电源，也可为重要负载提供紧急备用电能。本航空航天标准规定了电池功能特性的最低标准，这些功能特性是提高人员和飞机安全性所必需的，因为它依赖于电池。本航空航天标准的进一步目的是描述电池正常、非紧急功能中使用的特性。

It is the purpose of this Aerospace Standard to provide for the definition of the requirements of vented type, rechargeable, Nickel-Cadmium batteries of the form generally used in aircraft. These batteries serve as power sources for engine starting and also function to provide a source of emergency back-up electrical energy for essential loads. This Aerospace Standard establishes minimum standards for those functional characteristics of the battery which are required to enhance the safety of both personnel and aircraft, insofar as it is dependent on the battery. It is the further purpose of this Aerospace Standard to delineate those characteristics which are utilized in the normal, non-emergency functions of the battery.
