I've showed my car quite a few times, but I don't leave the battery on !!! It's one thing for maintenance, or listening to the radio for a bit, or loading the navigation, but leave it on for hours/days at a time?

For me, a cigarette sized one would work, but then, I know that there's not much discharge between the 5 day top off from the traction battery.

So, how big do you think the battery should be?

The LEAF's battery pack charges the aux if needed at any time while driving. IF you don't drive it for five days, then the battery pack will charge the aux.

The Leaf may shut off the acc load once the battery gets to a low point, or it may recharge it.

I do. I like people to get a feel for how the cool tech in the car works, and to play some tunes for the show attendees. The second accessory position (where the car is essentially on, but a drive mode can't be selected) is perfect for this, and my car will typically be in this mode anywhere from 2-6 hours.

I probably am the wrong person to ask that question of as I have no problem with the battery that is currently used. I simply don't see the ROI in changing it out for something else.

So what exactly is the difference between the first and second accessory position (what the manual calls "acc" and "on")?

I've been following this thread with some interest. As I see it, the current battery installation (25 pounds?) is well under 1% of the total vehicle weight. The performance gain in a lighter battery would be negligible at best... You've probably got that much weight with junk in the trunk anyways... If on the other hand you just wanna get the lead out...well...whatever... 8-)

I've got that much extra weight on my belly! I would just go on a diet before I changed my battery out to save 25lbs!
