Our set lasted 5 years in our sailboat. We used it at anchor and at the dock. Can't complain!

If you're having issues with an AGM battery, you need to check out what part of your charging system is not functioning properly. An AGM uses a fiberglass like separator to hold the electrolyte in place. The physical bond between the separator fibers, the lead plates, and the container make AGMs spill-proof and the most vibration and impact resistant lead-acid batteries available today. Even better, AGMs use almost the same voltage set-points as flooded cells and thus can be used as drop-in replacements for flooded cells.

If you're experiencing premature failure with an AGM battery, something is amiss with your charging system. You need to check your charging system for inadequacies/out of spec charging. AGM batteries are bullet proof and a MUCH better value over the long haul.

I'm stunned to hear complaints in other reviews. I have two Group 31 SeaVolt AGM batteries on each side of my Bertram 31 (total of 4 batteries). They start my 454 Mercruiser big blocks with gusto, recharge quickly, and run all of my electronics, pumps, underwater lights, and refrigerator without any issue. This will be the 3rd season with these batteries without any issues or drop in performance to date. They are a major upgrade in both value and performance compared to the name brand marine wet cell dual purpose batteries I had previously used. I highly recommend these batteries.

These 2 seavolt batteries are in a small fishing boat which is used every 3 weeks or so. For the first year and a half they worked great, held a charge and were very reliable. Quite suddenly both failed (during a 4 week window of non-use). One shows and "open cell" diagnostic and the other developed a case split. I could not find any evidence to pinpoint the cause of failure. I would recommend to a friend because the price was good, but with the caveat of my experience.

I replaced gel batteries with West Marine agm in my offshore heavy duty workboat. The agm are powerful and absolutely reliable, attributes that are essential to working in the Gulf.

I have used them with much better results than any other "service free batteries" as Starter Batteries for the 750HP Volvos on my 54' boat and the groupe of House Batteries to power lighting and electronics.

My 1yr old SeaVolt AGM threw an "Open Cell" code after one year. This was not a cheap battery and I am not happy.

Bought this battery to run the Ocean Kayak Torque trolling motor. Fished several hours a few times and the battery performed good. Will keep an eye on it to see how long it performs well.
