I have come to the conclusion that I need to replace my house batteries. As I do some research, I have found that all advice says that all of the house batteries should be the same "type". Flooded Lead Acid, AGM, etc.
In my rig, only owned it for 8 months, and still learning, I figured out that I have 4 200ah AGM sealed Lead acid batteries. Two of the AGMs have the blade connection and don't list the CCA rating, while the other two have the standard battery pole and connection, and list the CCA. As I read HandyBob, he indicates that the two that don't list the CCA are real deep cycle batteries, while the other two, are "hybrid". They even have the words "Super Start" on the bar code sticker. When charging, the Magnum 2812 charger supplies about 13.7 volts during absorb phase, which is below the manufacturers recommended 13.8 - 14.5 volts. I have the battery type set to AGM 2 on the remote.
With almost everything off except the furnace, I couldn't even get through the night while boondocking the other night.
Am I right on my diagnosis?
