IMHO your symptoms never suggested the problem was your battery. In my case, what made me suspicious of my fuel pump relay was that:

- with it jumpered, fuel pump worked and the measured fuel pressure was at spec so it wasn’t the pump
- only happened intermittently when temps outside were super low
- removing and reinstalling relay would result in successful start
- engine wasn’t getting fuel when I had the no start condition

A new relay was super cheap ($10?) and a worthwhile test and ultimately ended up solving the problem. You should try that next to eliminate that from the list.
