Whatever battery you get, its life is hugely extended by use of a CTEK charger/conditioner which keeps it in top condition....not that cheapbut still a fraction of the cost of a new battery so a good deal given the extension of life....ours is always connected when not in use...the CTEK has settings for AGM motorcycle batteries which are appropriate for our application
Always kept mine on a Battery Tender. My battery , the original, lasted six years.
