A battery pack communicates intrinsic battery information with a battery powered device over its battery voltage terminals. The battery pack detects a start-up voltage transition across the battery voltage terminals. In response to the detected transition, a sequence generator generates a data burst representing the intrinsic battery information. While the data durst is being communicated over the battery terminals, a current limiter limits battery current supply for a current-limiting time period.
