ABSTRACT:
Disclosed is a water-proof, gas pervious casing for a battery capable of containing a plurality of battery cells. The casing is made of a gas impervious, water-proof material that completely encapsulates the battery cells. A recessed region in the casing contains perforations, allowing gases to escape. This perforated recessed region is covered and filled with a plurality of layers of gas pervious sheets, one of which is water-proof. In addition to the recessed region, the exterior of the casing of the battery contains an electrical connector terminal which is surrounded with a water-proof seal. When the battery is installed in an electrical appliance, a cavity wall forms a water-proof seal with the battery to prevent moisture from entering the terminal region of the battery. On the exterior of the casing, adjacent to the recessed region, is a series of spacers are mounted which provide channels for exhaust gas to flow when the battery is snugly installed into the battery cavity of an electronic appliance. Lastly, the exterior casing of the battery contains a gripping device which allows the battery to latch on to a protrusion in on an electrical appliance when the battery is installed into the electrical appliance, preventing the battery from being inadvertently separated from the electrical appliance.
