AG13 Battery Overview

The AG13 battery is a small, 1.5V button cell commonly used in portable electronic devices. With a capacity of about 138 mAh, it measures 11.6 mm across and 5.4 mm thick, making it compact yet powerful for its size.

AG13 batteries come in two main types: alkaline and silver oxide. The alkaline version is widely used, while the silver oxide version offers longer-lasting performance. Both types share a similar structure, featuring a zinc negative electrode and a positive electrode made of either silver oxide or manganese dioxide. The electrolyte solution, which may contain silver chloride and sodium hydroxide, facilitates the chemical reactions that generate power.

These batteries are frequently used in small devices, including wristwatches, calculators, toys, remote controls, LED flashlights, and medical tools like digital thermometers. Their compatibility with other button cell models—such as LR44, SR44, 357A, and A76—makes them a reliable and versatile power source for many everyday gadgets.
