Often it seems my life revolves around batteries! I mainly use strobe lighting, each taking 4 batteries, plus the Pocket Wizard triggers take 2 each. Small CR battery for the camera mounted Wizard, the camera batteries of course (At least the D700 bodies take the same historically as the D200 and 300, but the backup 7000 takes its own as does the little Lumix that's been taking all the PaD's so far!, then each Light Panel takes 6, plus the video batteries if moving pics are involved and the radio miss take even more..... Half my kit bags seem to be full of batteries or chargers. And now it looks like Nikon are bringing out a replacement for the D700 and I bet that doesn't take the same batteries as the 700.... Arghhhh. OK rant over :)
On the road this week with shoots in Warwick, Bicester, Chatham and Minley so hopefully a bit more chunky PaDs to come :)
