Jay, You hit it on the head, I was afraid that the wrecker guys would just drop the pack on the ground in the parking lot or even chase me off their property and dump it in the street on the hot asphalt, but they were really cool with it, parking this cart in a corner of their lot under a tree so I did not get the full brunt of the 93 deg weather while slaving through the hot hours of the day, it was almost 3 hours drive away (near Sacramento) so even though I left early in the morning, the holiday weekend traffic caused me to arrive around 10:30 and they needed some time to pull the Leaf from storage and find the pack. Funny story: I had paid for and was waiting for them to bring the pack out, then the workshop guy comes to the front desk: Where *is* the battery on the Leaf? So I explained: under the car. I actually walked back with him, he raised the forklift tines enough that we could peek under the car and I pointed to the area between the 4 wheels and said: there it is. He also was a little hesitant for dealing with the high voltage, so I asked him: did you pull the 12V battery out (I could see that it was gone from under the also missing hood) and explained that the high voltage can only come out when 12V power is applied to the relays that disconnect when the car is not in use. After that he was happy to unbolt the pack, disconnect the plugs and cart it out for me to work on. At the end of the lunchtime he dropped by again to look at the contents of the pack with the words "you learn something every day" and I like that attitude.
Bruce, Indeed the shell is quite heavy. The top is single layer of sheet steel and probably around 40 lbs because I could carry it with some effort, the bottom I did not handle more than shifting it a bit on the cart, but seeing that it is double walled with some reinforcements, it must be at least double the top shell so likely around 80-100 lbs. This means that the entire battery pack in its enclosure is likely 40-50% heavier than the weight of the modules, which in itself are 4 cells in a metal jacket. BTW, I did put a short description with every pic so you have an idea what they are about, unfortunately the upload feature of Flickr put them in the wrong order, you see them from end to start. I don't have a blog to give the story with the pics but I did post them as public to be able to share the innards of a Leaf pack. Looks very well done.

That's a full days work! At least that cart put it up at a nice working height so you didn't have to stoop over all day....
