The reason I used gels and now AGMs is nothing to do with lasting a long time and everything to do with having acid in bilge during a hurricane :( I could buy high quality wet cells like golf carts ($) or Rolls ($$$$$$) and get a long life out of them or just swap out cheap batteries every few years. In my former business I dealt with a large yacht that had 4 cracked 8Ds and acid everywhere besides for my own acid spill adventure. IMHO there is a significant safety advantage to AGM/Gel batteries. I also had a 24 volt airplane battery spit acid all over my face. My dog would be coming to work with me every day if I hadn't still had my sunglasses on.

My GNB group 27's are now heading into their 6th year and I have abused them (let the electrolyte get low to expose the lead plates). They still hold their charge under a load test. My point is that if you don't need AGM's, a good quality lead acid battery has proven that it can last a long time if properly used. Bob Abbott AZURA C&C 32 - 84 Halifax, N.S.

The reason to buy expensive AGMs? No off gassing, no adding water, supposed to work laying on their side or when submerged. Ours are located under the aft berth, so I didn't want hydrogen gasses building up there. The batteries started the engine several times when we were heeled over 45 degrees stranded on a sand bar, and we got off. No acid in the bilge.

Because of shipping costs, it is likely that different brands come off the same assembly line and are just branded differently. I also suspect that warranties are mostly a marketing gimmick and have little to do with battery longevity. The cost of honoring longer warranties is just a selling expense, not an indicator of quality. bob07052
