Silver-Oxide 9.5 x 2.1 mm Batteries Comparison Chart In very low drain devices, the use of silver-oxide batteries is highly recommended - use a good SR920SW battery and forget about it, often for years. Silver-oxide SR920SW/370/371 batteries do cost slightly more than alkaline LR69/LR920/LR921/AG6 batteries, but they offer larger capacity, more constant voltage and they often have a longer shelf life. Their shelf life is typically 5-10 years, although there are models with a shelf life of just 3 years, but also with 10+ years. Silver-oxide SR920SW/370/371 batteries are commonly used in wrist watches, small electronic devices, small flashlights, remote controls, and even toys. When being slowly drained from 1.55 to 1.2 volts, their typical capacity is 40-55 mAh. Their cut-off voltage is 1.2 volts and they feature much more constant voltage during operation than alkaline batteries. 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. You need to correctly enter the anti-spam text.370, 371, LR69, LR920, LR921, SR69, SR920SW Battery Equivalents, and Replacements We will endeavour to respond as soon as possible. These silver oxide 370/371 button cells are used extensively in calculators, watches, and certain photographic applications due to their stable discharge characteristics.Įnergizer 370 Watch Battery equivalent: 370, 370/371, 371, 371BP, 537, 605, AWI S18, AWI S21, Citizen 280-31, D371, GP371, KS371, LR921, R371, SP371, SR69, SR920SW, SR921, Seiko SB-AN, Seiko TR920SW, V371 and V537.Īlso known as: D370, D370/371, 537, 280-51, SR69, Timex Z, SR921, SB-BN, SR920W, AG6, S21, B370H, 370, SR920, 1188SO, TR920W, V370, SP370Įnergizer 370 Watch Battery is compatible with: watches, computer, keyless entry, consumer electronics and hearing aid devices. ![]()
