Different battery?

I'm in France at the minute and don't have a very good up to date picture, but have alook at this which is when I first fitted the battery on that side, and before I installed a new battery. The battery in the pic is a standard Jeep Wrangler 4 ltr battery and is 242 long, 175 wide and 175 high.
I have now fitted this battery

which does everything I want and more. Plenty powerful enough for all winches, but not of course a deep cycle battery. Depends what you want to use it for.

is the Varta battery installed in place of the original?

No, its installed instead of the one on the passenger side. Its just an old photo of when I first did it, that battery worked for a bit but was old when I put it in there. It was a stop gap really until I got the Varta. There's no battery in the original position, just the winch solenoids, battery cut out and winch cut out.

the second battery powers the winch only . the winch has now been removed and is on ebay. i was just trying to explain the available size in the passenger side.
