![]() One side of the battery is made of Nickel Oxide Hydroxide, and the other is made of an alloy of several rare earth metals. The chemistry inside the battery that stores the electrical charge. Here’s our guide to the terms you need to know to make an informed choice. Rechargeable batteries are pretty simple devices, but there’s a lot of jargon surrounding them. In instances where I had to step away from observing the test, I set up a GoPro camera to record the operation of the fans, just in case one stopped running before I got back. ![]() When the blades stopped turning, the time was noted and the test was stopped. Our flashlight was operated at maximum brightness-roughly 350 lumens-as we recorded how long it stayed lit. For these tests, we ran our fan at maximum speed, recording how long it kept rotating. To see how long the batteries in our test group would last, we used them to run two devices: a small battery-powered fan and a powerful flashlight.ĭrawing 0.6 and 1.4 Amps, respectively, these devices allowed us to measure how long each battery can run during low-drain and high-drain use. We tested AA batteries as these are the most commonly used size for modern electronics such as TV remotes, smart doorbells, and outdoor security cameras. So we tested them by doing just that, using two high-end rechargeable battery chargers (a La Crosse BC700-CBP and a SkyRC MC3000) to measure the amount of charge that each of the batteries could hold, testing four of each and averaging the result. The most important things about rechargeable batteries are how much charge they can hold and how quickly they can deliver it. And most people don’t need that many batteries anyway.Īll batteries were completely charged before testing began.
