Old man on a bike
I have went through the GAMUT of batts for Motorcycles from uber high compression V Twins to the 8.7 to 1 easy spinning R3(IMO) and the best battery I have found (I have spent 350 for Shorai LiFePO4 to the 100 ish for Yuasas) and IMO the best AGM batt made in the USA is made by East Penn Mfging in Pennsylvania and goes by the DEKA brand or the Big Crank Brand. This company makes the OEM batts for HD and I was shocked at how much better the Deka brand batteries build quality was than the Yuasa, Interstate and etc.....
AND...They make the DURALAST GOLD ETX20L sold at autozone..Same as the Deka or Bigcrank and you can get 20 per cent off..
Check Amazon's review of the Deka ETX20L ..56 reviews...5 star
and like TRIICK said leave it on a Float tender.
I think the Deka batteries are just fine. I had one in my Harley. My problem with batteries is...1st...I want an AGM and 2nd...I want to be able to take it from a shipped dry state to wet by adding the acid pack myself. I never want a battery shipped wet and ready to install as you never know how long it has been sitting around on someone's shelf. Last battery for the Rocket was a Yausa shipped dry that I added the acid pack to. Just my personal preference.
