battery recommendation in the US?

[65fstbck]

Greetings all, and apologies for what I am sure is a silly question with an obvious answer: Is there a go to battery for Series 2 Fulvias and/or a recommend vendor for picking up a replacement battery in the US? This will be my first new battery as a relatively new owner and the one I have now does not appear to have a direct replication as far as my initial searches of US auto parts and battery stores.

Greatly appreciate any and all guidance and suggestions. Many more to follow as I start getting ready for spring driving!
