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...

- Turn off Wi-Fi. Your iPad's Wi-Fi connection drains the battery, whether or not you are using it connected to the internet. That's because your iPad constantly looks for networks.
- Turn off Cellular Data. Some iPad models have a built-in data connection. If your iPad has a cellular connection, the iPad battery drains when cellular data is enabled, whether you're using the internet or not.
- Turn off Bluetooth. You probably have the idea by now that wireless networking of any kind drains battery life. It's true. So, another way to save battery life is to turn off Bluetooth.
- Disable AirDrop. AirDrop is another wireless networking feature of the iPad. It swaps files from one nearby iOS or iPadOS device or Mac to another over the air.
