It sounds like you are using Alkaline Batteries.
Under the best of conditions you will only get about 30 photos before they expire with that camera.
I suggest you buy some NiMH rechargeable AA batteries and a charger.
They will last much longer before needing a recharge.
The Kodak "Pre-Charged" NiMH batteries are a good choice.
it usually happens after taking 2-3 pics in a row. using the zoom even shortens this interval. the batteries are new and there's no other apparent problem. when the batteries are completely new it takes a bit longer to do so. but after a very short use this pathology begins again anyone's familiar with this?
