Several different brands of AA batteries. Try to purchase batteries that all have roughly the same expiration date (at least within the same year), and note the price you paid per battery. Here are...Several identical flashlights that take two AA batteries (get one flashlight for each type of battery you plan to test)NotebookClock or watchChoose a day where you’ll be able to monitor your experiment all day. Make sure to start your experiment in the morning!Label each flashlight with the model of battery you will use that flashlight to test.Load each flashlight with two of the appropriate model of battery.Turn all of the flashlights on at once. Note the time, and record it in your notebook.You may have found that name brand batteries don’t live up to the hype! In addition, there isn’t necessarily a correlation between how much a battery costs and how it performs. However, you may have found that alkaline batteries last longer than non-alkaline batteries.
A battery generates current through a chemical reaction, where new chemicals are formed on both sides of the battery. In general, the more chemicals a battery has that can change into other chemicals, the longer it lasts, and this is partly what explains why alkaline batteries have a slight chemical advantage over their non-alkaline counterparts.
A great way to expand this experiment would be testing how a battery’s expiration date affects how long it lasts. Do older batteries perform more poorly? Test the same brand and type of battery, but test individual batteries with a range of expiration dates. You could even investigate which type of battery technology—alkaline or non-alkaline—will g...

Seventh Grade, Experiment with Batteries Science Projects. (6 results) Build and test your own battery, out of coins, a potato, metal and saltwater, or even one that collects static electricity. Or analyze what affects battery performance. Imagine telling your friends about your latest science project: using a battery to make a light turn on.
Science Fair Project Idea. You probably use batteries to power different devices every day, ranging from toys to TV remotes, without giving it much thought. Figure 1, below, shows some common types of batteries. Eventually the batteries will die and you have to replace them with new ones (or recharge them if they are rechargeable batteries).
Method & Materials. You will test the performance of three different types of batteries at three different temperatures. You will need an air-conditioned room, three Energizer AA size batteries, three Duracell AA size batteries, three Eveready AA size batteries, three AA battery-operated table fans, a clock or stopwatch, and an assistant.
Results. Our experiment showed that Rayovac outlasted all of the other batteries we tested by more than two hours. The Eveready battery, which is a regular, non-alkaline battery, lasted only 6 hours and 35 minutes. The Duracell lasted 15 hours. The Energizer lasted 22 hours and 15 minutes. The Rayovac lasted 24-1/2 hours.
