What's behind our battery Ratings?

Experts at our National Testing and Research Center tested 12 models in batteries to see which ones perform best.
We look for:
  • Overall score
    This is based on ratings from Camera and Flashlight tests. The displayed score is out of a total of 100 points.
  • Camera
    This is based on the total number of shots a cell provided when tested under conditions designed to mimic typical digital camera use.
  • Flashlight
    This is based on the total hours of flashlight life a cell provided under conditions designed to mimic typical household flashlight use.
