The main function of absorbed glass mat is to resist vibration. I'd disregard anything else anybody says about them, they do not have any more cranking power, or last any longer than a regular good quality battery. Auto parts stores will have you thinking they can cure cancer but not so. Optima AGM use 'gel' in them, can be turned any position, regular cheaper AGMs can use regular liquid acid, but thinking they still can run somewhat out of position due to fact that the mat absorbs the acid to not let it splash around to weaken plates and cause a short or loose connection. Still, no reason to spend big bucks to me unless you 4WD in the boonies a lot. Then, yes. Other than that, when could you ever need a battery that works on its' side?...........Really?.............Upside down???

Some people..........................
