A microcontroller, processor, and/or software (SW) monitors a battery degradation indicator such as battery State-Of-Health (SOH), impedance or other attributes, and calculates battery degradation rate and regulates burst power, battery charging speed and/or battery charging limit to meet users' expectation of battery service life. The microcontroller, processor, and/or SW increases the burst power, battery charging speed and/or battery charging limit when 1/SOH or impedance change rate (or related parameter) is smaller than expected and there is more longevity budget than expected. In another example, the microcontroller, processor, and/or SW decreases the burst power, battery charging speed and/or battery charging limit when 1/SOH or impedance change rate (or related parameter) is greater than expected and there is less longevity budget than expected.
