I also use these chargers on regular, flooded cell batteries of all sizes, and very small, AGM batteries that make the PC680 seem big by comparison.

Why the recommendation for a 12V charger for the small Odyssey batteries?

Here's the Yuasa -

Sounds like a good option. Float mode to maintain. The only major benefit the Odyssey charger provides over the Yuasa maintainer is that it will recover a deeply discharged Odyssey battery. But of course the Odyssey charger does cost considerably more.
