 Sony 391/381 (SR1120/W/SW) Silver Oxide 0%Hg Mercury Free 1.55 volts  batteries. Sony was the first Corporation to provide the first mercury  free silver oxide battery to consumers. Silver oxide batteries are  primary cells that have a high energy/weight ratio. Silver oxide is used  as the positive electrode (cathode) while zinc is used as the negative  electrode (anode) with an alkaline electrolyte. Sony silver oxide  batteries provide an extremely high quality, compact battery for the  high performance devices today. Sony also ensure consistent reliability  and performance in every cell. While Silver Oxide batteries are known  for mainly wrist watches the application usage due to the high energy  density and discharge characteristics have given the cells a broad range  of application usage. Applications: Insulin Pump, Watches, Calculators,  Electronic Clinical Thermometers, Remote Controllers, Portable Gaming  Systems, Keyless Car Remotes, Radios, Bike Lights, Portable GPS  Systems/Bike Computers, Computer/Communication Equipment, camera's and  many other devices.
