Abstract : Damage to Edison type BY carbonaire batteries has been reported in connection with buoy pocket air tests. Reported herein are the results of different tests designed to simulate the battery pocket air tests and to determine what air pressures and procedures could be used to prevent physical and/or electrical damage to the BY type batteries. The double electrolyte spill valves were tested separately as well as with the batteries for operating characteristic at different pressures. The BY batteries were tested in an air tank in inclined (20 deg. from horizontal) and vertical positions. Air pocket tests were simulated with hot and cold electrolyte. Battery pocket air pressure was released with the battery inclined and vertical and tests were conducted to determine air flow characteristics through the carbons. The only completely successful test configuration of battery and spill valve required the battery to be in the vertical position before the 5 psi battery pocket test air pressure was released.
