Maybe some pics would help.
Sugarwood, have you loosened the hold down clamp and tried to move the battery towards the center line of the car? Your picture is not clear on the positive end of the battery with respect to clearance.
Something is wrong with the battery placement or size. OP's picture shows no access to positive terminal. If this were the same across all 911's there would have been products made to remedy by now.

Great post, Bob, as usual.
No, I did not loosen the battery. Why?
I simply attached a trickle charger and went to bed.
The next morning, I went for a nice long XMAS drive across state lines.
I will try moving the battery, to see if the clamps then fit, for the sake of documenting this archive.

But, the premise of starting this thread was to figure out how 1000's of 911 owners have jump started their cars "in the wild" over the years.
My assumption is that you will not have an extension bar and hex socket bit to move the battery. So, as it sits, it's impossible on the road with only jumpers.

So, your other questions are the crux.

I use a size 48 battery. Pretty standard.
Maybe AGM batteries have their posts inverted to the outside?

I would love to see photos of other 911's battery bays.
How many people here can attach standard clamps to their (+) post?
Snap a photo and maybe we can get to the bottom of this mystery, as Bob posed.

That's awesome. But, how did you get the spanners to stay put? Were they balanced delicately ?
