PM100 has a built-in voltage charging relay (VCR), which offers a convenient source to charge the
service battery by alternator whilst engine is running. When the starter battery reaches 13.4VDC with
threshold time delay, the VCR will charge the service battery from the alternator. VCR will continue the
charging until the starter battery voltage drops under 12.8VDC.
NOTE: The PM100 when charging from the starter battery does not provide the 5 stage charge. It simply
takes whatever power and charging is available from the vehicle alternator.
