1. A battery pack for powering a device, comprising:
- a rechargeable battery having a positive and a negative terminal;
a sensor for monitoring a parameter related to operation of the rechargeable battery;
a memory for storing a plurality of data related to operation of the rechargeable battery, or data related to an operational parameter of a device being powered by the battery, each data being associated with a time stamp derived from a clock value provided by a clock when the data is stored in the memory; and
a processor powered by the rechargeable battery and in electrical communication with the sensor and the memory, the processor configured to receive signals from the sensor and to store the data related to operation of the rechargeable battery extracted from the signals from the sensor in the memory, the processor also configured to determine the clock value from the time stamp of the last data stored in the memory prior to a complete power loss of the rechargeable battery and to reset the clock after power is restored to the processor by the rechargeable battery so that the next time stamp increases in time.
