SR/LR/AG/SG Button Cells: IEC SR series batteries are silver oxide chemistry and provide 1.55 volts, while IEC LR series batteries are alkaline chemistry and provide 1.5 volts. Similarly, SG prefix batteries are the silver oxide chemistry version of the alkaline AG prefix. Since there are no 'common' names beyond the AG designation, many places use these four designations interchangeably for the same sized cell, and they will all fit and work. The only difference is that silver oxide chemistry typically has 50% greater capacity than alkaline chemistry. In low-drain devices like watches (without lights) this isn't very important, but in high-drain devices like blinkies, key chain flashlights, or laser pointers silver oxide is preferred. Often the free 'demo' batteries that come with a device are the alkaline version.
Round button cells have heights less than their diameter. The metal can is the positive terminal, and the cap is the negative terminal. Button cells are commonly used in electric watches, clocks, and timers. IEC batteries that meet the IEC standard for watch batteries will have a W suffix. Other uses include calculators, laser pointers, toys, LED "blinkies", and novelties.
