I bought a replacement. Got the most CCA they sold for my car. Cranks like a dream and was able to check that was was getting 14.5 volts from the alternator. In fact, I probably should have thought about the dragging starter, but it’s below 0 here and it seemed normal. The new battery cranked the 0w-20 filled 2.4 like it was no big deal.
It sat all day without a battery while I stole my daughters car to go to work. Driving it this morning, my transmission stuttering problem is gone, which is probably just because of the “reset” from being without power all day.
