I believe that is the same size as my 2004 EV, with the canister and tools beside the battery.
My original Spark battery lasted 11 years. It was getting weak, but still working. I replaced it with an Odyssey PC680-P last winter.
Just a bit over one year later, that Odyssey got where it wouldn't start the bike.
A local BMW shop had a pricey Yuasa YT19BL-BS AGM that I put in. It is a bit taller and barely fits. I only have a couple of months on it so I don't know how it will be in the long run
The Odyssey has a two year warranty, and I eventually got a free replacement. I had a bad luck with Odyssey batteries on my Centauro too. I had a HUGE Odyssey brick in a California that I installed around 2001. I suspect it is still going in that bike.
One interesting thing on the Yuasa. When I go to idle, it holds the voltage a little longer/better than the Spark or Odyssey ever did. I suspect it has more plate area (I didn't weight it). If so, that is a good thing.
