'22 RT starting slowly after sitting on tender - replacement Battery?

[Kromm]

I have a 2022 RT that I purchased just over a year and a half ago. We have been having some very wet weather here, so it's been sitting in the garage on a Battery Tender. It was a nice day yesterday and I had some things to take care of, so I decided to take the Spyder. When I started it after disconnecting the Tender, it turned over very slowly (gave me a VSS Fault). I had some things to take care of in another town about 25 miles from where I live. After arriving and taking care of my business, when I got back on the Spyder it almost didn't start (another VSS Fault). I had one more stop to make, this time it almost didn't start (another VSS Fault).

I have read complaints about the factory batteries. My question is what is the recommended replacement battery?
