ABSTRACT:
Batteries are moved along a first roller type conveyor to a leak testing station, above which is located an assembly having a plurality of nozzles matable over battery cell inlets. A first set of alternate cells is supplied with air at a given pressure, and metering means notes pressure change. Thereupon, the remaining alternate cells receive the same treatment. If the cells do not leak, the battery advances from the testing station along the roller conveyor. If a leak is detected, a push bar connected to cable means below the rollers ejects the battery transversely from the testing station along to a second conveyor, thereby isolating leaky batteries either for removal or further testing to locate more precisely the leak.
