ABSTRACT:
A storage battery is provided which includes a casing and a cover secured to the casing. The cover includes a body having a top surface and a peripheral skirt; the top surface having a plurality of vent apertures, at least one negative terminal and at least one positive terminal, and an elongated recess having a bottom, four side walls and an open top. The negative and positive terminals have extensions exposed at opposite ends of the recess, and a state-of-charge indicator assembly is mounted in the recess and electrically connected to the negative and positive terminal extensions. The state-of-charge indicator assembly is sealed in the recess by relatively thin adhesive seal or membrane applied over the open top and adhered to the top surface of the cover. The membrane is provided with percent charge and test switch indicia thereon.
