Optima Yellows are dual purpose, Reds are starting, and Blues come in both versions (differentiated by the shade of gray on the case, confusing to many, including some of their dealers).

Since JCI bought the line from Enersys/Odyssey, quality has declined to the point that none of the "colors" are suitable for true deep cycling usage.when people here are saying 'Optima' are they meaning the Yellow only, or has the Red somehow (improperly) become conflated with these sort of deep cycle operations?
That is, as I said, true for **all** sealed deep cycling lead.You are making my argument for me, so thanks for that. Odysseys are robust but fussy, which takes them out of the "keep it simple" approach that I had recommended
East Penn / Deka AGM are not great quality for deep cycling.
Their FLA and GEL are great.

UPS use case requires a completely different battery design than deep cyclingEast Penn / Deka AGM are not great quality for deep cycling.
Their FLA and GEL are great.
Now that's really weird as Deka AGMs are often used in very large UPS installations.
