Re: Replaced Start Batteries Reply #25 – January 05, 2023, 04:10:39 pm Quote from: wolfe10 – January 05, 2023, 03:14:16 pmSince you are on shore power (inverter/charger charging the house batteries), use the boost switch to jump voltage back up to 13+ VDC on the chassis batteries.Yes, the batteries could be bad, OR it could just be that the draw exceeds the amp output of your chassis battery charger.Chassis (start) batteries could be bad, however they are new I just replaced them. I was having similar voltage indications and I assumed that since my start batteries were old and tired they might have been the problem. The new batteries did not change the symptoms I still see. Yes, I can turn the boost on and watch the start battery voltage climb up to the value of the house batteries in a very short time. I agree that it is a distinct possibility that something intermittent is exceeding the amp output of the trickle charger terminal of the Victron Multiplus 3000. Thanks Quote Selected
