Noticed that the few EFBs retailed here (USA) are running about 5-15% over standard Flooded (long-warranty tier) prices at the same stores (AZone PepBoys, etc). Guess they are re-branded Exide/Stryten M51R-EXs, rather than, say, Vartas.
All claim enhancements like 1.5-2 greater "cycles" etc. Have the impression that EFBs have been more common elsewhere in the world for a while. So people must use them in standard cars, too. (Still flooded lead-acid so not even a question of whether or not to adjust "charging" profiles in older vehicles, as to better treat AGMs.)
Is there any real data on their operational lifetimes in regular cars? (Perhaps especially those that sit or only take short-trips.) Seems paying, say, 10% more for significantly longer life, might figure favorably in cost/value.
PS I do realize many here consider batteries a not-to-overthink generic consumable to be changed-out every x years.
