Hypothesis
Different brands of batteries will last for different amounts of time and the higher the price of the battery, the longer it will last. Also, batteries refrigerated for one month will last longer than batteries kept at room temperature.

Experiment
Thirty-two batteries, including four brands (DieHard, Duracell, Energizer, Radio Shack) were tested. Sixteen of the batteries were refrigerated for one month while the other half were at room temperature. The batteries were tested in a 0.5 Amp flashlight which took two AA batteries. Batteries of the same brand and refrigeration were paired to be put in the flashlight.
