Surprised no comments but I'll add one - when installing this battery, make sure you have the proprietary Shimano "tube plug tool." When I was assembling my road bike I thought I had a short in the downtube connection to the junction box. I thought maybe the battery was bad. Ended up finding a Reddit comment about battery installation that said it was a MF'er to install and that you MUST use the special tool. After using the tool, I was able to finally get the connection to "click" and (most) all of my problems were solved.

Rare these would ever be in high demand. They are expected to last 11-25 years
