Shakedown trip on a newly acquired 31' Hunter (1984) turned up battery issues. I have a starting battery (no issues with this battery) and a 3 battery bank of AGM batteries. The batteries are maintained on charge 24/7 while in the slip. We left the slip, motored for one hour, sailed for 4 hours and motored for another 30 minutes to our anchorage. While under sail, we ran our Adler refrigerator, the radio, electronics (GPS, Autohelm on but not used, depth sonar and one small 12 volt fan in the v-berth). While at anchor we used the refrigerator, radio, water pressure pump, one fan, anchor light). My the morning, the house bank of 3 batteries were dead.
On my last vessel I could easily go 24 hours or longer on a single house battery.
Right now I'm not sure if I left the electronics switch on or not. This would include the auto pilot. The GPS was off and stowed. The depth sonar may have also been left on as well.
Based on past experience, I would expect a bank of 3 batteries to last more than 24 hours with charging occurring at two intervals, one for an hour and another for 1/2 hour during that time frame.
One other issue with these batteries is that they are very hot when on the charger. The wood on the seat above the batteries is very warm to the touch. Is this normal?
I have added pictures of my charger and the labels on the batteries if this helps in offering a reply.
Thanks in advance for advice.
