Your V-Max have a pretty good capacity at 235aH. But you pay for the extra 15aH. 220aH is adequate for me.
Although I was leaning toward replacing all my batteries with Costco wet cell Interstates (my original Interstates went 12 years before showing failure signs), I’m now thinking I’ll go AGM’s, and when I researched last fall the best deal was actually at Batteries + Bulbs. They offer a 10% “order online coupon” that takes the price below most others. Unfortunately, Costco doesn’t offer 6v deep cycle AGMs, or they’d likely be the better deal.
I see now that Batteries + has changed some batteries and prices, so you’ll have to do your own shopping around. The specific GC2 AGM I thought I was considering isn’t on the website, and the other options have been shuffled; but pricing seems better. As I recall though, my local store had a other available ones than what was on the website. So I reckon we’ll both be shopping around a bit.
They do have a Crown, like Chuck refers to:

Lithium is big bucks and usually means charger modifications and specialized tech labor that add up fast. Although the wave of the future, for most of us they’re not practical retrofits.
I’ll be checking their 31-MHD chassis ones also. Their Duracell’s were on my list, but I may check AGM chassis options there and at Costco too.
