The purpose of this recommended practice for capacity rating for storage batteries in passenger rail car service is to set up uniform qualification procedures and
criteria for use in such service. It will make available to the Passenger railroad/Operating Entity comparable information as to the capacity to be expected from batteries of the various types and sizes offered for use under conditions of low and high discharge rates. By consideration of the information furnished under this method, determination of the proper battery for a given connection, load discharge rate, and required hours of discharge, both at initial rating and 80 percent final rating will be greatly facilitated and service requirements satisfied.
