huskychemist:I bought Energizer 2500 mAH rechargables that came with their own Energizer charger. I took 160 pictures on Saturday...never turning the camera off on three dives, using the flash on 90% of the pictures...and had lots of power left.
Not sure if this applies to your batteries, but mine came with a warning that it may take a few charge cycles out of the box to get them "up to speed" in terms of longer battery life.

It seems I had the same problem you mentioned. After going through a few cycles of charging them, I am now getting plenty of time out of them. I have now taken over 230 photos on my last charge and it is still going.
Thanks for that info.
