Varta Button cell V392, 1 piece

High-quality Varta silver battery. Much more durable than an alkaline battery, making it preferred by professionals for small electronic devices. Silver batteries differ from alkaline batteries by having a higher voltage level (1.55 V compared to 1.5 V for alkaline batteries) and the construction of the battery itself: in silver batteries, the cathode is made of silver oxide and the anode is made of zinc. In alkaline batteries, the cathode is made of manganese oxide and the anode is made of zinc oxide. In both battery types, the electrolyte is potassium hydroxide. Silver batteries last longer than alkaline batteries and are therefore commonly used in devices such as watches, calculators, counters, and other electronic devices. They have the best capacity-to-weight ratio. Technical specifications: Type: 392 Diameter: 7.9 mm Height: 3.6 mm Weight: 0.6 g Electrochemical system: Silver battery Voltage: 1.55 V.
