Oh my, let me tell you. If you aren't paying almost twice for an AGM battery over lead acid, your getting junk. Optima batteries are some oif the worst AGM batteries, as of two years ago. They went to **** after they switch manufacturers.
Sears platinum Marine AGM's are rebranded Odyssy batteries and with a free THREE YEAR over the counter replacement warranty, cannot be beat.
Second runner up is the same rebranded Odyssy batteries from West Marine.
Third would be Cabellas.
I've never installed Deka AGM's, but I'm sure they are equally good.
But do not buy optima's.
I'll 2nd that. I went through (warranty) 3 optima red tops in 5 years in my ski boat. 1st time thought it was cuz I didn't maintain it over the winter. 2nd one died the same early death with battery maintenance. Same with 3rd one.
4th new one, still on warranty, pulled from boat in the fall, put in my old jeep. That was in 2009?, maybe 08. Jeep has been parked indoors, outside, used to put it on a maintainer once in a while, but not for the last few years. Maybe gets started every few months for a few minutes, sat for 18 mo, no charge, no start and it's still kicking. Just fired the jeep up a couple weeks ago to move the boat.
Since I only paid for 1 battery gues I could say it's lasted 8 years lol.
Plus I had a blue top go tits up in the same amount of time, with off season maint.
Odyssey batteries are quality IMO. Bought a pair for the new boat one in 09 other one 2 yrs later. The older one is from 09. Pulled them both from the boat and put in the truck in '13. Still going strong at 5 and 7 years old.
Have a newer set of Die hard re branded Odysseys now in the boat. Much cheaper than odyssey and good performance so far 2 years in. Boat sits on a maintainer when not in use (like 360 days a year!).
Dekas are highly recommended by guys with big boat stereos too.
