Back in the day my dad used to say "never buy a car in its first model year, there are always unforeseen problems that won't be discovered until it's been in production for at least a year."

I have a feeling that new batteries are the same. Whether it's a new chemistry or a new factory building a new version of a known chemistry, I think I'll treat new model years of a battery the same way my dad treated new model years of cars, and always stand on the sidelines for at least a year.
