AgfaPhoto Lithium Coin Cells, as compared to alkaline coin cells, have a higher voltage range of 3V, and are fit to operate in extreme circumstances (- 20 / + 60 °C). They can be used as a power source for small electric devices. The "CR" mark of the coin cells indicates lithium manganese dioxide chemical composition. Due to their design, coin cells can operate small size household objects such as toys, watches, pocket calculators. They are recommended for operating products that are not in continuous use. Lithium coin-cell batteries are non-rechargeable, discharged batteries must be collected only in designated containers.
