Army Develops Rpid-Action Tester for Storage Battery A new rapid-action tester fof storage batteries has been developed de-veloped by the Army Signal Corps at its Fort Monmouth, N.J., engineering engi-neering laboratories. The heart of the tester is a specially spe-cially designed indicator mounted on the dashboard or steering column col-umn ol a vehicle. It tells the driver at a glance whether he has enough power in the battery to start the engine. In addition, the indicator also shows the amount of the charge, the temperature at which the battery will freeze, and whether use of extra accessories such as a radio, heater, or lighter will bring the charge below the danger point. The device eliminates the need for unscrewing the cell caps as is now necessary for chemically testing acid contents of a battery.
