Battery PerformanceOur general method for battery testing is to reset the cameras to their default settings. Then, take 5 pictures without the flash and 2 pictures with the flash until the battery is dead. For more information on our battery test, please refer to our Testing Procedures page. Because only the Olympus had the ability to shoot in raw format (TIFF), we chose to use the highest JPG settings on all 3 cameras. Otherwise, the numbers would not have been comparable because the Olympus would have had a significantly lower number if shooting 15MB files. For the Kodak and Casio cameras, we used 2AA NiMH Power2000 2500mAh batteries charged overnight in a Power2000 wall charger. For the Olympus camera, we used the included LI-10B battery after charging it to capacity. All batteries were fully drained before charging for the test.

We were surprised by the results of our battery test. The Casio outperformed both the Kodak and the Olympus. One thing that is worth noting about the Olympus camera is that because we were forced to use a 256MB card (thanks to the 256MB card-size limitation), we had to format the card twice as often, adding more strain to the battery. Despite this difference, any of these cameras would do fine in one day of heavy shooting. However, the benefit of the Kodak and the Casio is that you can charge extra batteries in advance to bring with you. Keep in mind that for our battery test, we shoot continuously until the battery is dead. Casual shooting, where there are long gaps in between picture taking sessions, will result in shorter battery life than what we were able to achieve.
