Superduty Batteries

I love my little panoramic-making robot.  I tried to do one today of lunch at a Scouting event but there was a bit too much movement for the shot to turn out clearly and there were a lot of decapitated people and disembodied heads.  Anyway, I took the device to camp to do a pano at sunset, but ran out of charge after the rechargeable batteries had taken two panos for over 800 pictures.  Fine work in my book.  Anthony opened the trading post and I got 6 new “Super Heavy Duty” batteries.  They felt light but I figured I’d give them a try.

Guesses how many shots they lasted?
