The battery listed for my 2007 had the terminals reversed. My bike may be unusual. It may be a short production thing. Maybe Piaggio got a load of different batteries and everyone else's is wired the way the Shorai configurator expects. Who knows? Second tip double check your terminal configuration.
There was no hope of my leads reaching the terminals. I looked to see if I could put in new, longer cables in but that's an ugly looking task.
So following their instructions I called Shorai. I reached someone right away and although they had to refer me to tech support who got back to me later, the process was started immediately.
They replaced the battery with one with opposite terminals and shipped out to me all at no cost. Tech support is very good.
The shipping wait gave me time figure out how to mount it which had it’s own challenges. The battery is longer and lower requiring me to slide it back and re-route the negative cable.
