Hello,
A few months ago I replaced my batteries with 8 4D AGMs. Since it has cooled down and I won't have AC running I decided to test how long they will last without shore power. I currently have my auto start at when coach reached 23.8 for fifteen minutes.
I have fridge running and other minimal items that keep the coach alive. This morning at 11 am the batteries read 25.2. This is the actual reading on the Trace inverter LCD monitors.
We will see how long it batteries will keep up before generator kicks on.
