Abstract

A battery, usable with one or more battery support units and/or electronic devices, contains a memory which contains a mailbox. The battery receives a request from a battery support unit or an electronic device to write error data in the mailbox. In response to this request, the battery stores the error data in the mailbox. The battery then receives a request from a battery support unit or electronic device to read the error data from the mailbox. In response to this request, the battery transmits the error data to the battery support unit or electronic device that requested it.
