Abstract
Abstract A device is provided, for testing batteries for leaks, preferably adapted for the testing of batteries in a ''''dry'''' condition, prior to introduction of liquid (acid) thereinto. The device is adapted to be engaged and applied to a battery, with inlets disposed over cell openings of a plurality of cells of the battery, with gas (generally compressed air) being provided at some predetermined level of pressure to the batteries, and for giving a visual indication regarding pressure of a plurality of cells at the same time. The device is constructed to be adjustable for accommodating variously sized batteries.
