BA–17.—This battery consists of a single cell commercially known as the No. 6 size and is probably most generally used in electrical work. The cell is cylindrical and is contained in a paraffined cardboard carton. It is about 6-1/2 inches high and 2-5/8 inches in diameter, and its weight about 2 pounds. It has an open-circuit voltage of 1.54 volts; an internal resistance of 0.05 ohm, increasing to about 0.08 or more as the cell approaches exhaustion; a shelf life of 9 months; and a service life of 3 months. The short circuit current, when new, is about 30 amperes. This cell is of the same size as BA-10 and the two can be used interchangeably.
