This is not a slam at any given manufacturer or product but neeed some input. Wondering if anyone has had problems using an AGM battery. Used a Braille battery in my 30 AV8 build due to confined space and low weight. Now after having it for a year and a half and a year of actual use it took a crap and wouldn't crank my flattie. Not exactly a high comression big HP egine! Battery is rated at 425 CCA worked fine till now and was put in cool dry storage this winter with a AGM rated charger. Ran the car for over an hour two days ago and should have been fully charged as the volt guage read plus 12v constantly. Connections tight at terminals,not exposed to heat,elctrical sytem always closed down after use and no electrical drain. Manufacturer rep. told me to expect about a two year life span? Offered a pro rated return credit which I think is fair but not sure spending over $200 every two years is a wise move. Typically I have a tendency to over think and over engineer things so thinking I cut my loses and go back to a wet cell battery. BTW I've had zero trouble in my 34 using a Redtop Optima for over 8 years storing it the same way.
