History of AAA Batteries #

AAA batteries, also known as triple-A batteries, are a type of small, cylindrical battery used in many everyday items. They are one of the most popular battery sizes, and are commonly used in items such as remote controls, toys, flashlights, and other portable electronics.

The AAA battery was first developed in the late 19th century by the National Carbon Company, which later became the Eveready Battery Company. The first AAA battery was introduced in 1907, and was designed to be a smaller, more powerful version of the AA battery.

Chemistry of AAA Batteries #

AAA batteries usually contain alkaline, zinc-carbon, or lithium-ion chemistry. Alkaline AAA batteries are the most common type, and are typically used in low-drain devices such as remote controls, flashlights, and toys.

Zinc-carbon AAA batteries are a cheaper alternative to alkaline batteries, but have a shorter life span. They are typically used in low-drain devices such as smoke detectors and clocks.

Lithium-ion AAA batteries are the most powerful type of AAA battery, and are typically used in high-drain devices such as digital cameras and portable gaming systems. They have a longer life span than alkaline or zinc-carbon batteries, but are more expensive.

Typical Uses of AAA Batteries #

AAA batteries are used in a wide variety of everyday items. They are commonly used in remote controls, toys, flashlights, digital cameras, portable gaming systems, smoke detectors, and clocks.

Design of AAA Batteries #

AAA batteries are typically cylindrical in shape, and measure 44.5 millimeters in length and 10.5 millimeters in diameter. They are typically made from zinc or manganese dioxide, and are encased in a plastic or metal housing.

The positive and negative terminals of AAA batteries are typically located at the flat ends of the battery. The positive terminal is usually marked with a plus sign, while the negative terminal is usually marked with a minus sign.
