I think Lifeline is the best AGM battery. I bought four for my 2000 Dutch Star back in 2001 and when I bought my 2005 Dutch Star I swapped the AGMs to the new motorhome. So they have been going strong over eight years. I have traveled fulltime with them and spent over 1,000 nights boondocking often draining them to near 50%. Most of the boondocking has been in warm (or hot) weather, but I have probably boondocked 100 nights in cold weather.

Once a year I wash the road dust off the batteries and check the torque on the cables. I have no idea how many more years they will last, but they are still operating as good as the day I bought them.

I tell people that I think standard flooded wet cells like the Trojan T-105 or the Interstate U-2200 are the best bang for the buck (I like the Interstate price better) UNLESS. and I stress that UNLESS, there is a problem with accessing the batteries for service or there is a problem with ventelation of the battery area.

In that case AGM's are the answer

Lifeline is beyond a doubt the best AGM

The rest, far as I know, are more or less equal. That includes MK Deka (East penn Battery) and more.. I have MK's in my problem box. Interstate U-2200 in the no-problem box

The exception to the avove is Optima. .Optima is a very rugged AGM battery that, when it's called for, (IE: Off Roaders) is the very best there is. It can, as Timex used to say, "Take a 'lickin and keep on a'ticken" But it's only 75% battery (That is for any given foot print you get only 75% the amp hours) the reason for this is clear if you look at it, it's 1/4 air space due to the sprial design.
