Abstract
Multiple battery authentication security levels and procedures alert a user of counterfeit or unapproved batteries that are installed after manufacture of the wireless communication device. In an exemplary a battery authentication system, a mobile device sends a pre-stored plain text to a battery installed in the mobile device. An approved battery receives the plain text and performs an encryption algorithm on the plain text. Encrypted text is sent back to the mobile device. The mobile device compares the received encrypted text with a pre-stored encrypted text. If the received encrypted text matches the pre-stored encrypted text, then the battery is authenticated. Upon completion of the authentication of the installed battery, the mobile phone conducts normal battery and charging operation. If the received encrypted text does not match the pre-stored encrypted text, then the device enters authentication failure events that limit the use of the battery.
