I got ahold of 50 of these, but just don't need all of them. They were used in a backup server for 2 years, and are in really nice condition. They look just like the Batcap 800 and Kinetik 600 batteries, just that they have tabs instead of threaded terminal inserts. 17.2ah of reserve, 15lbs, and roughly 6.5" x 7" x 3"...just like the Kinetik and Batcap.
1 = $55 shipped
2 = $95 shipped
4 = $175 shipped
I have 20 of the black top ones and 12 of the solid gray ones.
