Abstract
Devices and methods for detecting and reporting a battery tamper event with regard to an intrinsically-safe or explosion-proof device while the device is located in a hazardous environment. The device may include a location sensor for determining that the device is in a hazardous location. While in the hazardous location, the device may detect an open enclosure event using a sensor and, if so, it may monitor for detection of a battery tampering event. The battery tampering event may include battery replacement or battery charging. The battery tamper event may be reported to a remote server over a wireless channel when it occurs.
