Battery leak testing apparatus

摘要

Apparatus for detecting leaks in hydrogen-generating electric storage batteries including suitable enclosure for the battery, means for overcharging the battery to generate hydrogen pressure therein, and a sensor for detecting the presence of hydrogen in the enclosure. The battery's vent will be suitably plugged or routed to divert any hydrogen escaping through the vent from contaminating the air in the enclosure. A hydrogen accumulator/separator attached to the enclosure concentrates the hydrogen at the hydrogen sensor.
