My original camera was a Fuji Finepix 6900, cost me £900, but left it in a very nice camera bag with lots of accessories(total £1200) on the roof of my car at Snetterton and drove off!!
This had a inbuilt rechargeable battery but cost me £45 every year or so for a new one, as they just conked out, the replacement was what I now have and the AA battery bit is ace, as said find somewhere that sells batteries, and I'd be amazed if they didn't have AA's.
At least I am a bit more careful where I leave it now!!
