VARTA silver battery V303 (SR44) 1 pcs

High-quality Varta silver oxide battery. Far longer-lasting than alkaline batteries, and therefore preferred by professionals in small electronic devices. Silver oxide batteries differ from alkaline ones in their higher voltage (1.55V compared with 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 of battery the electrolyte is potassium hydroxide. Silver oxide batteries last longer 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-weight ratio. Technical specifications: Type: 303 Diameter: 11.6 mm Height: 5.4 mm Weight: 2.3 g Electrochemical system: Silver oxide battery Voltage: 1.55 V
