Optimas are actually AGM battery's "Absorbed Glass Mat" Which Typically are 10 to 15x more vibration resistant than other battery's
I have Optimas now BUT only had them for two years, so I can not yet say they are the best.
I will say that if everyone put a Good onboard charger (that is designed for the type battery you have) 90 percent of "battery" problems would go away. I know this for
experience.
