Anyone using AA batteries on their camera should know about this. Panasonic Oxiride batteries, designed with the digital camera in mind. I tried every brand of disposable alkaline battery, fooled around with several makes of rechargables, until I found the Panasonic Oxiride battery. It was like the clouds parted and the sun shone through....... These batteries deliver 2.4x as many pictures compared to regular alkaline batteries. The great news is that they basically cost the same price (unlike the over priced Duracel Ultra - and yes the Panasonic Oxiride battery kicks its butt too). The battery offers an initial volatge threshold of 1.7 VDC (normal AA batteries off 1.5 VDC, and recharables 1.25 - which is just slightly above the point where your camera thinks that battery is exhausted).
I could not believe how fast my flash charges up and is ready for its next shot.
Just wanted to pass on the word.
