You seem to assume the bottom plate is inches away from the bottom of the battery case. What if it is only 1/4 inch or less?

It was a hard right off the main drag and I was probably going 25-30mph. I did need to make a soft left coasting into a parking spot, but 30 seconds later, the sediment apparently settled enough to allow the engine to start right up again.

It did pass a load test and the battery would also start the car without fail. However, the engine died on a turn more than once, probably due to sediment bunching up opposite the direction of the turn, shorting out the battery. It is not possible to simulate the inertia experienced on a turn during a load test.

I checked all the battery connections including the battery to ignition switch connection the first time it happened. All battery cables, wiring and connections were clean, tight and in pristine condition.
I have not had any problem since replacing the battery and I have made the exact same turn at the grocery store parking lot several times since then many times. I have absolutely no doubt that the old battery was shorting out on turns.
