Manufacturers offer a cycle life, a number of cycles that the battery can go through before it loses a certain amount of its capacity. All batteries lose capacity when used, meaning that they can store a little less charge with each cycle.

Cycles or Recharge Life: Each full charge and discharge is one battery cycle.1 mAh is a flow of one milliamp over an hour, so a 2500 mAh battery can deliver 2500 milliamps (or 2.5 Amps) for one hour, or 250 milliamps for 10 hours. A measure of the amount of charge that can be stored in a battery. Some batteries minimize this by adding extra insulation inside the battery. Typically, a NiMH battery will lose up to half its charge if stored for a year.

All batteries lose a certain amount of charge over time, even when they are not connected to anything. You should never use a NiMH battery (like the ones in this guide) with a non-NiMH charger, as this can damage them. Charger: the device that controls the flow of charge into a battery.

When the battery is used, this is reversed, creating a flow of electric charge out of the battery. When the battery is charged, the Nickel Oxide Hydroxide gives up a Hydrogen ion, which is absorbed by the alloy. 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.

We tested AA batteries as these are the most commonly used size for modern electronics such as TV remotes, as well as some 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. Until 2012, I was the VP of Editorial Development at, where I created the testing protocols that are still used for products such as TVs, dishwashers, coffee makers, and refrigerators. In that time I have tested everything from automatic coffee makers to wearable computers. I’m Richard Baguley, and I have been testing and breaking technology for over 20 years. All batteries were completely charged before testing began.
