It's an easy answer with the Guest, if the red light is on for a prolonged time, you have a problem. I check mine after about 24hrs from turning it on to make sure it's in float (green light).

Hello Tom,

I have a question. When you are speaking of charging your batteries, you are talking about a separate charger?

I have a 1999 Marathon with 2 4K invertors, AGM Jell Cell batteries that stay charged using the invertors with either shore or Genset power source. I have no other way to charge the batteries.

Why does one need to charge the batteries using a charger?? I leave my coach plugged into shore power, with the frig, air set to low a few other electronic items on and all seems fine. What am I missing here, should I be considering something else??

How can I monitor the AGM's other then with the invertor monitor??

I have read on this forum about batteries failing but mostly because of low fluid levels, cooked. What can happen to the AGM's and doesn't the invertor monitor how much charge is required? batteries like all else are expensive and would sure like to ride these 2007 ones for a while.

Thanks,

Bruce
