Battery Replacement for 2019 212X

[slickstick]

Coming up on three years old for the boat so want to replace batteries on my 2019 212X... Here in Florida car batteries always seem to die soon thereafter and looks like it could be same for the boats. I never charge my batteries on a tender but never had any issues with stock even after a month or two not firing her up. Looking for as good or better than stock, but shouldn't need anything crazy. Holding the charge between runs would be most important. I do have an added radio and bilge pump and will hangout at the sandbar for a bit.

What is stock group/size? Would like something that fits in stock tray under the cover. I can't find a dang catalog to look this up or see it in the manual. Looks like deep cycle battery for both house/starter may be the way to go. AGM seems preferred.

Anything I am missing links to the best deals out there?

This Duralast seemed like a good deal at $99 each but not AGM and only a one year warranty which makes me weary. https://www.autozone.com/miscellane...deep-cycle-marine-starting-battery/107675_0_0

This Duracell is more pricey at $220 each but AGM and 30 month free replacement Duracell Ultra BCI Group 24M 12V 78AH 800CCA AGM Deep Cycle Marine & RV Battery - SLI24MAGMDC

A bit off the mark since it's from the service manual for our 2012 SX240: "Marine Grade Gourp 24 Dual Purpose, 675 Marine Cranking Amps".
(No "stock tray" for us.)
FWIW, on the advice of someone here on the forum I went with an Optima Blue Top for our SX240 (two of them actually) back in 2015 and they're both still going strong... That said a quick check of current prices and they're eye watering!!!
