A Comprehensive Guide to LR41 Battery: Powering Everyday Devices
The LR41 battery, also known as the AG3, 392A, and 192, is a small, button-shaped battery commonly used in a wide range of electronic devices. Despite its compact size, the LR41 battery delivers a reliable source of power for various applications, such as watches, calculators, digital cameras, hearing aids, remote controls, and other portable devices.
Understanding the LR41 Battery
The LR41 battery is a silver-oxide battery characterized by its high energy density and long shelf life. It typically measures 7.9 mm in diameter and 3.6 mm in height, with a nominal voltage of 1.5 volts. The LR41 battery contains silver oxide as the positive electrode and zinc as the negative electrode. When the battery is connected to a circuit, the silver oxide reacts with the zinc, producing an electrical current.
