Abstract
A vented battery includes an aperture 108 in the battery housing 104 for venting built up gases inside of the vented battery 104. The aperture 108 is covered with a sintered metal vent 204. The sintered vent can be molded in the battery housing, staked to the housing, friction fitted into the aperture, or attached using other commonly known methods. In an alternate embodiment, a vented battery 200 has at least one battery contact 210 formed from sintered metal allowing for the venting of gases inside of housing 104. The battery contact 210 performs the dual function of allowing the battery 200 to be vented, and also act as electrical battery contacts which allow battery 200 to be connected to external devices. A communication device 300 includes a radio 302 that has a radio battery retainer 310, or other external housing member made from sintered metal thereby allowing for radio 302 to be vented.
