I advise NEW2elec and other forum trolls that if they don't want to buy the battery, they are free to simply pass and move along in life, without making unwanted comments.
To everyone else,
Contrary to what NEW2elec puked up, the battery is NOT degraded and, according to Zero's website, this power-tank is compatible with SR's ranging from 2015 - 2021, similar to what I originally wrote when I posted the ad. However, I'm not convinced it won't also fit in a 2014 model and I'm also not convinced that it isn't a plug-and-play installation. When I inspected a 2014 model, all of the wiring and plugs looked identical to my 2016.
If, like NEW2elec, you are one of the few people who even HAS a local dealer (many of us do not) and if you enjoy throwing money at said dealer (many of us do not) then by all means: go there and spend the $3,000+ that the local dealers charge (according to Zero's website.)
In the meantime, my working, low-mileage power-tank battery is still for sale for $1,000.
