Primary Batteries

Primary batteries are non-rechargeable batteries that are designed to be used once and then disposed of. They are also known as disposable batteries. Primary batteries are made of a variety of materials, including zinc-carbon, alkaline, lithium, and silver oxide, and are designed for different applications depending on their chemistry and construction.

Zinc-carbon batteries are the most common type of primary battery and are used in low-drain devices such as remote controls, flashlights, and clocks. They have a relatively low capacity and voltage, making them suitable for low-power applications.

Alkaline batteries are another common type of primary battery and are used in a wide range of applications, including toys, radios, and portable electronic devices. They have a higher capacity and longer lifespan than zinc-carbon batteries, making them suitable for higher-drain applications.

Lithium primary batteries have a higher energy density and a longer lifespan than other types of primary batteries, making them suitable for high-drain applications such as digital cameras and portable medical devices.

Silver oxide batteries are used in small electronic devices such as watches, calculators, and hearing aids. They have a high capacity and a long lifespan, making them suitable for low-drain applications that require a long battery life.

Primary batteries have a limited lifespan and must be disposed of properly to avoid environmental damage. Recycling programs exist to collect and recycle primary batteries, and it is important to follow local regulations for battery disposal.
