In this age of ubiquitous electronics, batteries have an astounding importance in our everyday lives. As we buy and use different brands, we come to wonder, "Which of these is actually the best? Is it worth it to go for a big name brand?" To answer these questions, I set up an experiment to test the endurance of four different battery brands: Duracell, Energizer, Rayovac, and Sunbeam(a dollar store brand).
Step 1: The Materials and The Hypothesis
To test the comparative endurance of the four battery brands under study, I used four Mini Maglite xenon lamp flashlights purchased from Walmart on the same day. As for batteries, I bought an eight pack of Energizer AA batteries, an eight pack of Rayovac AA batteries, and a four pack of Sunbeam dollar store AA batteries. The flashlights came with Duracell, so I used those batteries for the Duracell test. I did, however, find a price for a Duracell eight pack in order to compare prices more effectively in the conclusion.
My hypothesis was as follows: Dollar store batteries will be the first to go, with one of the bigger name brands coming out on top. I had no basis for distinguishing between the three top brands, but because the Duracells came with the flashlights, indicating that they might be preferable, I hypothesized that Duracell would last the longest.
