I have replaced three batteries in two and a half years (Advanced Auto Silvers). The same brand is in my IHC Scout, Nissan ZX, and BMW and I have had no problems at all with any of those. Without knowing of any other reason for a "bad" battery, I can only assume the lack of straps in my Delorean IS the problem. I had been blaming the Ducellier alternator, generally poor electrics on the Delorean, or terrible luck. The Advanced Auto people have always tested and replaced them with little or cost to me, but I expeienced that sudden "no start" situation where it was very inconvenient. Would a neoprene matting or sorbathane pad provide some shock absorbancy or would this set me up for a fire hazard should the battery leak? Steve Jarvis #3542
