My young friend at work just told me that I bought the wrong kind of digital camera. She meant for me to buy one with a special rechargeable CAMERA BATTERY INCLUDED,
but I misunderstood her and the no-help-at-all people at the electronics store sold me one that takes not-included rechargeable AA batteries, which last about 2 hours between charges.
I am not planning to return the camera, because I don't have the strength to put myself through the hassle, but next time I'll know better!
