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.Type: GrantFiled: April 18, 1994Date of Patent: March 21, 1995Assignee: AER Energy ResourcesInventor: Lawrence A.
