Battery enclosures are typically sealed metal or plastic shells designed to protect the battery from dust, debris, and moisture, such as rain, snow and car-wash sprays. Any one of those elements can damage battery cells and ancillary electronics, so an effective enclosure keeps those potentially harmful materials away from the battery.
