VARTA silver battery V392 (SR41) 1 pcs

High-quality Varta silver oxide battery. Far more durable than an alkaline battery, and therefore preferred by professionals in small electronic devices. Silver oxide batteries differ from alkaline batteries in their higher voltage level (1.55V compared to 1.5V in alkaline batteries) and in the construction of the battery itself: in silver oxide batteries the cathode is made of silver oxide and the anode of zinc. In alkaline batteries the cathode is made of manganese dioxide and the anode of zinc oxide. In both types the electrolyte is potassium hydroxide. Silver oxide batteries are more durable than alkaline batteries, which is why they are often used in devices such as watches, calculators, meters and other electronic devices. They offer the highest capacity-to-mass ratio. Technical specification: Type: 392 Diameter: 7.9 mm Height: 3.6 mm Weight: 0.6 g Electrochemical system: Silver oxide battery Voltage: 1.55 V
