Abstract
A battery pack (10) has a memory (26) for storing a password. Upon connecting to a host device (12), or similar load, the battery waits for a data word to be communicated from the host device over a communications channel (22). If an incorrect data word is received a predetermined number of time, or if an initial power time period, as defined by a timer (30), is reached, a switch (16) is opened, thereby disconnecting the battery cell or cells (14) from the load.
