[QUOTE="Constant Mesh, post: 871226, member: 615"] At the end of its 4+ year life my OE battery had problems after brief hot shutdowns (gas stops, etc.). Yet, when I measured the voltage before a cold start it always measured fully charged. When I installed a new battery the problem disappeared. So, it was the battery. Don't think the problem is related to hard cranking when hot, etc. Don't think the problem was a function of the battery being heat soaked. When you're underway at a reasonable pace the battery is not being heated all that much from radiator heat. When you briefly stop, the battery can't absorb all that much heat in 10 minutes. It's a 10 or 11 lb. mass of lead, electrolyte, and case. It won't change temperature all that much in 10 minutes. [/QUOTE]
