Battery
Did some searching here and saw a nice discussion on which battery is highest recomended.
But my question is slightly different. I once read an article on a early 928S where he purchased a smaller battery which was much lighter in weight. Anyone know what this battery number is? Size? Said it saved 40 pounds? For those in the UK... not money but weight :-)

He was probably talking about one of the Optima line of batteries. Sealed and lighter from what I understand. No reason you can't go with a physically smaller battery, just make sure you get one with the proper top posts that will fit and has enough cranking amps and you should be fine. You'll also probably need to figure out a new way to secure it as well.

Such a battery is great for racing etc but not for general use - it will have a much lower capacity say <20Ah vs ~ 70Ah for the stock battery - what does this mean...
It can't really handle repeated attempts to start the car or many short trips with parking in between - not a good choice in my mind... I have one (Odyssey PC680 MJ 17Ah) but only as a backup battery - alone its not sufficient for day to day use. If the alternator dies this battery would run the car for a few minutes under high load (night/fans) vs probably 30-40 minutes with stock battery Alan

Yeah, the stock battery is a heavy monster. I had to do some roids just to lift it and install.

Odyssey is one of the brands of racing battery many like, tiny, big amps. Optima batteries aren't smaller or lighter, they just don't spill.
