While it's not exactly survival oriented, this is by far the friendliest of the forums I haunt, so I'll ask here:

I have a digital camera that runs on 2 AA's. It frequently sits for a couple of weeks or more between uses, and I'm tired of picking it up and finding the batteries dead. There is apparently some trickle drain, even when it's off.

I'm thinking of using 2 pairs of some kind of rechargeable, and keeping the batteries next to it on the shelf between uses. If I'm taking it with me, I'd pop them in for the duration. And I'd always have a fresh pair available.

It has a memory card for pictures, so I'm not worried about losing them with no batteries in the camera. I don't use the "date in picture" feature, so I don't care if the internal clock is current.

The different kinds of batteries available today just leave me confused as to which is best for this particular usage. Your thoughts?
