The majority of the jeep types and hummers use the Optima AGM's (Jumbo'd failure is the only one that I have personally heard of failing like he reports)
They are the hardiest of all batteries.
The off roaders like the optimas because they are so hardy... they are absorbed Glss mat... spiral would... they layers won't seperate no matter how much thery get banged arournd. This also the reason they look like a 6 pack of coka cola... it is also the reason that the Optimas have about 25% less capacity.
Since we humans cannot build anything perfect, I am sure there are others that have failed. I understand that the original manufacturing plant was moved to a lower cost manufacturing facility in a lower wage Country. Not to say they are not manufacturing to a rigid set of specs. But I will never spend $300 for a battery that the warranty was disallowed.
