Double AA batteries will not work in my digital camera . On the battery tester they show weak. But have power to light a flashlight
And run a small radio. Does a digital camera demand so much energy?

If the battery tester shows them as being weak.. then they are... and yes cameras do take a lot of power.

Sounds like a cheap answer but can depend on your camera and its electronics.

But YES, I know mine will stop and I can take out the batteries and still use them in kids toys for weeks.

Try to buy rechargeable batteries, I did this about a year ago, would never go back
