VARTA silver battery V377 / SR66 24mAh 1,55V 1 pcs

High-quality VARTA silver oxide battery. Considerably longer-lasting than alkaline batteries, which is why professionals often prefer it for 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 their construction: 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 equipment. They offer the highest capacity-to-weight ratio. Specifications: Type: 377 Diameter: 6.8 mm Height: 2.6 mm Weight: 0.3 g Electrochemical system: Silver battery Voltage: 1.55 V
