Abstract
An electronic device, such as a defibrillator/heart monitor, monitors a battery having a memory for an error condition while the battery is operating the device. If the electronic device finds an error condition with the battery, it transmits error data to a mailbox located in the battery's memory. Other electronic devices or battery support units, or even this electronic device at a later date, can read the error data in the mailbox and take an appropriate action. For example, the electronic device can read the mailbox and, if it finds error data placed there by itself, another electronic device, or a battery support unit, enables an indicator, such as an indicator that informs a user that maintenance needs to be performed on the battery.
