Abstract: Information handling system battery monitoring tracks battery usage for warranty coverage. A timer state machine running on the battery tracks time expired from initiation of a warranty period, such as the first non-manufacture boot of the information handling system or detection of a new battery interfaced with the information handling system. The expired warranty period and a unique identifier stored on the battery are communicated by a battery manager running on the information handling system to battery warranty site. The manufacturer of the information handling system applies the expired warranty period and unique identifier to determine warranty coverage for the battery.

Abstract: In a method and system for authenticating a smart battery for charging, the smart battery receives an encrypted random string. The smart battery is operable to provide power to a device. The encrypted random string is generated by a controller of the device by generating a random string and encrypting the random string with an encryption key. The smart battery decrypts the encrypted random string with the encryption key to recover the random string and transfer the random string to the device. The device verifies that the random string is unchanged to authenticate the smart battery for the charging. If the random string has been modified then the smart battery is disabled from the charging.
