  "textContent": "An improved battery condition determination for use in a dual battery system is disclosed. The dual battery system includes power battery means being connected to an electrical system including a starter motor, and starter battery means being connectable in parallel with the power battery means by a dual circuit breaker, whereby, when the dual circuit breaker is closed, the power battery means and the starter battery means provide a dual system voltage to the electrical system. According to the invention the following steps being performed during a time period when a starter motor is inactive: - determining, when the dual circuit breaker is open, at least one of an open circuit power battery voltage and an open circuit starter battery voltage, - determining, when the dual circuit breaker is closed, the dual system voltage, and - utilizing the dual system voltage and the determined at least one of the open circuit power battery voltage and the open circuit starter battery voltage for determining a relative state of health for the power battery means, wherein the relative state of health is related over time to a state of health for the starter battery means.",
