electricity - Why do 'dead' batteries work again after exchanging the places of the batteries in an electronic device?


My camera, which is powered by two AA batteries in series, would not power on. I removed the batteries, exchanged their locations, and the device worked again - for another 15 minutes or so.


The temperature of the batteries did not change, and only about few minutes passed before I discovered this.


Is there a physical explanation for this phenomenon?
