Have you ever heard about Silver Oxide batteries? No? That’s okay. Since these button type cells last a very long time and you rarely need to replace them (a tiny battery can keep a watch running for 3 to 5 years), they are less known. With a high energy-to-weight ratio and stable discharge characteristics, the primary batteries are used as a power source for precision devices such as watches, heart rate monitors, calculators, digital thermometers and other electronic equipment. And the cherry on top is, you can use them in the same gadgets that are compatible with Alkaline button batteries. Wide range available at BatteryDivision – shop now.
