Batteries have a typical cycle life assuming no more than about 70% discharged. Lead acid and AGM tolerate somewhat lower discharge but I suspect many of these failing batteries are almost fully discharged on multiple occasions and not charged properly. Think about how much more juice it takes to turn over a 6.2L on multiple occasions
