Button cell

Button cell batteries are small-sized, primary (non-rechargeable) batteries commonly used in watches, calculators, remote controls, measuring instruments, and medical devices. These cells have a flat shape with contact plates and are often available in types such as LR44, CR2032, CR1632, and SR626SW.

The button batteries are manufactured using different electrochemical systems — such as alkaline, silver oxide, and lithium-based technologies — providing various levels of capacity, voltage, and stability. Some types, though more expensive, offer longer lifespan and more stable performance even under low discharge rates.

This category aims to cover all user needs, from everyday-use batteries to professional-grade models, including products from well-known brands such as Duracell, Panasonic, Varta, and Kodak. Button cell batteries offer a practical and compact power source for portable devices where high capacity is not required, but reliable operation is essential.
