AGM vs lead acid marine batteries

[Bduck]

+1 AGM--Optima is really proud of their pricing. I used to buy the Sears Die Hard wet cell lead acid for any of my vehicles and finally purchased their AGM marine dual deep cycle/start in 2007 for the boat. After 15yrs that AGM is still holding a full charge. I added another AGM to my boat last year. It's another Die Hard marine. Advanced Auto Parts now has the Die Hard battery bought out from Sears which I purchased just under $200. Just recently had to replace the wet cell batt in my Caddy Escalade also purchased an AGM for it. I'm slowly transforming all my vehicles to AGM. On the average the wet cell only has been giving me 3-5yrs use and the price has gone up.
