Methods and systems of estimating an end of life of a rechargeable energy storage device in an energy storage system is disclosed. The system includes at least a motor, the energy storage device associated with the motor, a processing unit associated with the energy storage device, and at least one sensor operatively coupled with the processing unit and the energy storage device. The method includes measuring a most recent state of health (SOH) of the energy storage device after the system is started, storing the most recent SOH with at least one previously measured SOH, calculating a new replace-by date of the energy storage device based on the most recent SOH and the at least one previously measured SOH, and replacing a previously calculated old replace-by date with the new replace-by date, the new replace-by date being the same as or shorter than the old replace-by date.
