It takes considerable time to bring LA batteries up to 100% charge. I'm not sure how much you use your batteries, or if they are actually fully charged.
I've posted this many times in the forums and so far no one can fully explain what I'm seeing. I have an ammeter's shunt in the main negative cable connected to the coach batteries. The ammeter's readout on the cab dash can briefly show up to 70 amps going into the batteries at engine start-up then slowly tapers after that. After 3-5 hours of driving between campsites, it usually is showing zero amps flowing. The alternator starts out at up to 14.4 volts and slowly drops in voltage as we drive (I also have an engine alternator voltmeter on the cab dash). I assume that zero amps flowing means the batteries will not accept charging current anymore.
