Recently at Sam's Club I saw Duracell makes AGM TM batteries. Has anyone tried them yet ?
YES. In my opinion, one of the BEST AGM batteries on the market!
Not only do they have a high cold cranking amp but also high reserve capacity and amp hours. When cross checking other brands I found them to be higher than most (insterstate and optima included).
I put a set in my dad's boat last year and two of my buddies both have them. One of my TM batteries finally gave out this year in November. I'll be replacing them with Duracell batteries this spring from Sam's.
ARE THE AGM BETTER THAN WET CELL ?
I have 2, they seem to be great, I fish 2/5 times a week during good weather. They are a year old. No problems, knock on wood. My experience is that AGM's take a lot more charges than wet battery's. We will see.
Mike, they are good batteries and probly Best Buy out there on AGM. Plus as good a warranty anyone. Just double check that your charger can be set to charge or has the capability to charge AGM battery.
Duracell marine batteries are made by Deka. They can't hold a candle to Northstar or Odyssey when it comes to performance, but they aren't a bad battery and at the price Sam's sells them they are a pretty good deal. They had them for $154 for the group 31 before Christmas which was a heck of a price.
AGMs have a longer cycle life, which is the number of times they can be discharged and recharged, they are much less prone to damage than conventional flooded cells if left partially discharged and they charge a little faster. Downside is they are heavier than an equal capacity flooded cell and they generally cost around twice as much. The price on these at Sam's Club is what makes them attractive.
Because of the way they are made, an AGM is built with a lot of plates like a cranking battery so they have a lot of CCA, but you can still use them as a deep-cycle.
I have been running AGMs 31s on my 40 yr old ranger a few years now for both starting and trolling ( sears made by odyssey ). One thing I discovered is that my old 115 Johnson motor did not have a voltage regulator on it. I guess this was common back then and when i was running my boat it was putting out unregulated voltage to the battery, which would boil out the battery. I put a multimeter on it and checked the voltage as I was running down the lake and it was throwing out 19 volts to the battery. If I remember right, battery chargers are limited to 14.4 volts max for a 12 volt battery. On a typical battery when it boils out... just add fluid...but, what happens to an AGM? It has a vent and out gasses thru that... but no way to replace any lost electrolyte. I was able to find a regulator/stator kit that I added to my motor which now controls the charging voltage sent to the starting battery. If you run an AGM on your starting battery , and your motor is old like mine, you might want to check your voltage that the stator is throwing out and make sure you are not going to cook your AGM. All that aside, I love my AGMs for trolling. I troll crankbaits with the trolling motor and it is amazing how long I can go with them.
Catfan , please correct me if I mistated anything.

I have a Duracell for my trolling battery and it on its third season. Does everything I need.
Haven't tried them for trolling, but bought two of them for my Ford 7.3 diesel. Love em.

I've been thinking to going to AGM , I've been running 3 Interstates for cranking and Trolling 3-5 times a week all summer, my Interstates are/will be starting their 5th year this spring.....They have been ABUSED and I mean SEVEARLY ABUSED.... I Bow fish and run the Bowmount troller on top of lights and a Stereo blasting the oldies....
I'm kind of curious is it worth the extra $$$ to switch over and get a new charger? My charger is prolly as old as I am.....
I'm as old as dirt
