M.I. installed a Yuasa YTX20CH-BS in my 2013 Stelvio NTX. Given I bought it in November 2014, with a Battery Tender, I've gotten a respectable 4.5 years service out of it - which is a vote for a like kind replacement. But I really like Odyssey batteries, however, they don't make a model specific for the Stelvio.
I'd like to hear experiences of other Stelvio riders, with OEM or replacement batteries, before I spend +$120 on a new one.
