That's my experience too. No warning and then a no-start.
The no-starts are generally in the garage, at home, first thing in the morning (ie inconvenient but not too serious).
I did get 12 years out of the large trunk mounted conventional battery in the BMW though. In the winter I trickle charged that battery overnight every few weeks especially when I wasn't driving it much. I gave it some extra consideration due to the cost of a replacement and the high resting demands on the battery.
The Honda conventional battery lasted 8 years on the once and done (ie one no-start) approach.
