Skycorp 12V 170AH Lead Crystal Battery Leisure / solar / yacht / canal boat

  
Only used two of them, rest have never been opened. Used one for car in storage and a server backup - they work great! They are deep cycle, so can be run flat and re-charged without issue (unlike lithium batteries). Great for a powerwall, solar, yacht/canal boat. A friend runs everything on his widebeam canal boat off 4 of these, with another powering bow thruster.

The one out the box (in pics) has seen light use as a sever backup, willing to accept offer for it.
