![]() ![]() When used in devices that support low cut-off voltage, these batteries are also very reliable batteries. If alkaline batteries are used in electronic devices that have a cut-off voltage of, for example, 1.2 volts, the use of alkaline batteries in such devices is not recommended due to the very low actual capacity and unreliability of the device itself.Īlkaline LR69/LR920/LR921/AG6 batteries are cheap batteries, with a shelf life of 3-4, even up to 5-6 years, depending on the brand. Their cut-off voltage is 0.9 volts and the typical capacity when being slowly drained from 1.5 volts to 0.9 volts is 25-30 mAh. The accurate label for the silver-oxide battery is SG6, not AG6.Īlkaline LR69, LR920, LR921, or AG6 batteries have a 100% SOC (State of Charge) voltage of ~1.6 volts, but the nominal voltage is 1.5 volts. Note: Some manufacturers label even silver-oxide batteries as 'AG6' or similar, in order to emphasize that their battery can be used as an alkaline AG6 replacement. Their features and specifications are given in the following table: Chemistry LR920/SR920SW batteries are 9.5 mm in diameter and 2.1 mm in height and they come in two versions: alkaline chemistry and silver-oxide chemistry. ![]() LR920/SR920SW Batteries Features and Specifications leading to confusion when proper battery equivalent and replacement battery is needed.įortunately, most popular battery brands use SR920SW, 371, 370, LR920, or AG6 when labeling their LR920/SR920SW batteries. LR920 and SR920SW are popular alkaline and silver-oxide batteries commonly found in the wrist and other watches, remote controls, some toys, small flashlights, and similar. ![]()
