When in doubt, there are lists available of common devices considered to be high drain or low drain. Low-drain devices, such as remote controls, LED flashlights, small toys, and clocks, can function properly with standard alkaline, lithium, or rechargeable batteries. Manufacturers usually recommend AA batteries engineered specifically for high-drain devices, typically lithium or rechargeable batteries. A low-drain device only requires a steady trickle of power to work, but some AA batteries may be too powerful.Ĭommon high-drain devices include cell phones, portable gaming systems, remote-controlled toys, and digital cameras. A high-drain device draws a significant amount of power in a short amount of time, and some AA batteries cannot keep up with the demand. When choosing the best AA battery for a new electronic device, it is important to determine if that device is considered high drain or low drain. One advantage of rechargeable batteries is that they will self-balance, meaning an older battery will still perform well with a newer one, unlike disposable alkaline batteries that can become unstable when mixed. The first rechargeable AA batteries were made from nickel and cadmium (NiCd), but modern versions are more likely to contain nickel-metal hydride (NiMh) or lithium-ion (li-on).
