So far, so good. Purchased two for my Ram 2500 pickup with a 5.9 Cummins diesel. Truck has been starting every time with no degredation in battery performance or power. Have a low current drain that I have not been able to isolate and which impacted battery life with the Die Hards I previously had installed,so I put in two quick release isolators that are providing a temporary solution to the drain problem. Batteries remain fully charged between starts.
