Instead of storing spare batteries in a catch-all drawer or toolbox, consider using a nonconductive storage case. Storage casesĪlkaline dry cell batteries should not be stored in places where contact with metal is a possibility. A battery charging station is a worthwhile accessory to keep these batteries fully charged. Rechargeable battery technology has improved to the point where it makes good economic sense to invest in rechargeable lithium-ion or nickel-metal hydride AA batteries for most devices. Low-drain alkaline batteries should never be used in high-drain devices, but high-drain batteries can be used in low-drain devices if necessary.ĪA batteries should be stored in a nonconductive container out of the reach of children.īestReviews Features of AA batteries Battery chargers 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).

Rechargeable AA batteries: Recharging an AA battery involves reversing the natural flow of electrons and restoring the electrolyte to its original state.

It is important to note that lithium batteries are not rechargeable, unlike lithium-ion or li-on batteries. They are noticeably more expensive than standard alkaline batteries and are usually recommended for high-drain devices, such as drones, cellphones, and laptop computers.

Lithium AA batteries: AA batteries using lithium as an electrolyte are generally promoted as high power or long-lasting.

A few alkaline AA batteries can be recharged, but most have a shelf life of five to 10 years, depending on usage. The term “alkaline” refers to the chemical electrolyte inside the casing, which generates a steady flow of electrons until the chemicals lose their potency.

Alkaline AA batteries: Standard alkaline AA batteries are the most common type found on store shelves and come at an affordable price.

There are three basic types of AA batteries to choose from: The manufacturer will often include recommendations for a specific type of AA battery to use for maximum performance or those types to avoid in order to prevent damage. It is important to determine the ideal type of AA battery to power different devices. An insulated wire provides this connection, and the result is an electrical current that can power small motors or other electronics. The repelled electrons want to flow to the positive cathode but require a connection to form a closed loop. During a chemical reaction in the electrolyte, excess electrons flow toward the anode, but they have nowhere to go. In the space between these two poles is a chemical solution known as an electrolyte. The negative end is also called an anode. The positive end of an AA battery is also called a cathode.

How to buy the best AA batteries How AA batteries workĭry cell batteries of any size are essentially electronic fuel cells that depend on a chemical reaction to work.

Size AA batteries were first introduced by the Ever Ready company in 1907, although size D batteries had been available since 1893.
