My Deka AGM group 31 just died after 2 years. This battery was perfectly maintained (trickle charged with a smart charger), stored correctly, and lightly used. Way too much money to spend for such a short use life. I have had terrible luck with AGM batteries lasting more than a year or so regardless of the brand. I currently have more than 30 lead-acid batteries running in vehicles and boats and I replace only a few every year. I'm looking at going to a lead-acid battery for my Horizon. Anyone doing this? How are you enclosing it? Anyone used a sealed battery box with venting?
