Abstract

The apparatus provides a cover (14a) for venting gases from thin metal film battery cells having vents (68) disposed at the center of one end of the cells. The vents comprise cylindrical wells (72a) that recess into, and substantially fill, the top portions of battery cell cavities within a battery housing. The cavities are sized to hold the battery cells (18) securely and are configured to provide an electrical serial connection. The wells (72a) include pipes (71a) which extend outward from the bottom of the wells and lead from openings (76a) in the bases of the wells. The vents include fluid deflectors (90) mounted to and extending outward from a bottom surface of the baffles (75a) at the bottom portion of the pipes (71a). The openings in the pipes are covered with flexible valve caps (77a) and well lids (78a) cover the wells. The center point arrangement of the recessed wells permit gases from the battery cells to escape through the openings, yet restrict the electrolyte from exiting the housing. The base of the battery housing does not have vent openings and is interchangeable with the cover so that the battery may be oriented with the terminals near the top or the bottom of the case.
