The over-all dimensions of the battery are about 9-1/4 inches long and 1-5/16 inches in diameter. Its weight is slightly more than 13 ounces, or 0.83 pound. It has an open-circuit voltage of 4.6 volts, an internal resistance of between 0.45 and 0.6 ohms, a short-circuit current of nearly 10 amperes, a shelf life of 6 months, and a service life which depends entirely on its use.
