Abstract
A metal-air battery leakage detector is disclosed which uses a wicking material to absorb and propagate leaking electrolyte to a leak detection means so that the detection means is activated regardless of whether the leak is occurring in the vicinity of the detection means. In a first embodiment a substance that chemically reacts with electrolyte to change color is impregnated into the wicking material as the leak detection means. In the second embodiment electrodes are embedded in the wicking material and wired to an electrical circuit that is responsive to the presence of electrolyte as the leak detection means. In either case, a user has immediate knowledge of an electrolyte leak occurring inside a battery casing so that the battery can be removed from service before the leaking electrolyte can cause harm.
