alkaline button batteries
Alkaline button batteries are compact, high-performance power sources that have revolutionized portable electronics. These small but mighty batteries utilize an alkaline electrolyte, typically potassium hydroxide, combined with zinc and manganese dioxide to produce reliable electrical energy. Their distinctive coin-like shape and minimal size make them ideal for numerous small electronic devices. The construction features a positive and negative electrode separated by a specialized membrane, all sealed within a durable metal casing that prevents leakage and ensures longevity. These batteries typically deliver 1.5 volts of power and are available in various sizes, designated by standardized codes such as AG, LR, or SR series. What sets alkaline button batteries apart is their impressive energy density, allowing them to store substantial power despite their diminutive size. They demonstrate exceptional stability during storage, with a shelf life often exceeding 5 years when properly stored. These batteries excel in devices requiring steady, reliable power output over extended periods, making them particularly suitable for watches, calculators, medical devices, car key fobs, and small electronic toys. Their design also incorporates safety features like anti-leak protection and child-resistant packaging, addressing both durability and safety concerns.
