Quick summary: after we returned from a trip, I neglected to plug in the shore power, a senior moment I guess... Anyway, after a few days my DW returned to the RV to store some clean towels and stuff and then informed me that the lights in the RV were not working. Actually nothing worked. So then I noticed that the the shore power problem. I plugged into shore power and then we had AC of course but no DC, the display in the power panel was dead so I could not even tell if the charging system was even trying to charge. I checked all the fuses and breakers and found no problems. I measured the voltage on the house batteries (4 GC2 batteries wired to provide two parallel 12V batteries) and found about 1.9 VDC left. So, I just left it for a few hours thinking I probably ruined the house batteries.
The next day I went back and all systems were working now that shore power was available. The batteries showed normal voltage. So, maybe the batteries did survive???? What should I do now? Do a load test to see if the batteries work? Are they really charged?
I did a search for this question but didn't find an exact hit. Many postings mentioned that these really deep discharges will reduce the battery life or worse. These batteries are wet cell GC2's and they are about 3-4 years old. To my knowledge this is the only time they have been discharged this deeply.
