Systems and methods are disclosed for a warranty tracker embedded in a battery pack. In an embodiment, the warranty tracker may include a memory device and a warranty controller. The warranty controller may receive an electric current measurement indicating a rate of charge or discharge of the battery pack from a device that is external to the battery pack. A warranty value may then be calculated using the received electric current measurement and added to a stored cumulative warranty value. The memory device may store the cumulative warranty value, which may be used to evaluate warranty conditions. In various embodiments, the warranty tracker may also include a temperature sensor and/or a voltage sensor. The warranty controller may then use received temperature and/or voltage measurements in the calculation of the warranty value. In an embodiment, the stored cumulative warranty value may be used to determine expiration of a warranty.
