Operating temperature of between -20̊̊C to 60C.Chemical composition: This is an alkaline battery whose composition comprises of manganese dioxide at the cathode and zinc anode). ![]() SR44 are non-rechargeable and should be disposed after running out of power. They are also stable under different temperature conditions and tend to have a long shelf life. With a rated nominal voltage of 1.55 volts, SR44 use silver oxide as cathode and zinc as anode. The battery has other names such as SR44W and SR1154 and used in small electronic devices such as calculators, watches, digital thermometers among others. This means that SR44 is a silver oxide button cell battery with the diameter of 11.6m m and height of 5.4mm. The Prefix SR stands for the Silver Oxide. However, they are non-rechargeable hence should be disposed once they run out of power. They have a relatively long shelf life of between 2-3 years and a wide temperature range in which they can operate. With the rated capacity of 150mAh, LR44 are designed to be stable and reliable power sources to their respective application areas. These include calculators, watches, digital thermometers, small medical devices and toys. It is a perfect battery option for those devices that don’t need lots of power. ![]() The battery is cylindrical shaped and measures 11.6 millimeters in diameters and has a height of 5.4 millimeters. ![]() In this prefix, the L stands for alkaline and R for Round while the 44 refers to the physical size of the battery.
