Lifeline L16 AGM?

For the price you can buy six flooded lead acid deep cycle batteries with a life of more than 25 years, and pay as you go. So the breakeven point with the Lifeline is at 25 years. Is the warranty for that long and do you plan to hold onto the RV for that long as well? Makes zero sense for an RV to use these.

MMMMMMM....don't think so. I take it you are talking about 6X6V wet cells. 2 are needed to roughly equal the amperage of the single 4D. So that is 3 banks with your 6X6V. Each bank would have to last over 8 years. Not likely. Not without alot of careful maintenance & easy use. 4 years life per bank is more like it & even that is a stretch if well used. That gives 12 years total life span for those 6X6V wet cells.

Now it is not likely the the 4D Lifeline will give 12 years service either. 10 years should be about it. The thing is that the AGM will not need a drop of water. It can be mounted anywhere you please. It is not going to leak & corrode your steel battery frame. Until it gets near the end of its lifespan it will be worry & maintenance free.

Yes that Lifeline AGM 4D is very expensive. It costs about as much as the 6X6V wet cells. The one 4D AGM Lifeline will last about the same as all those 6X6V wetcells. While the wet cell owner is busy changing batterys every 4 years the AGM owner sits & watches. He has a battery lifespan 2-3 times longer than that wet cell owner.
