This is physically the largest battery that will fit a L322 - you will need to modify (i.e. remove or mount the starter fuse differently) the +ve terminal.
The battery was bought new in May this year, it works and tests fine, I'm selling it as with my current usage pattern, it's not getting a full replenishment charge so would eventually prematurely fail due to failure to maintain the charge so I've replaced it with an Autostop-rated EFB battery.
