![]() Most modern silver-oxide SR57/SR927/SR927SW batteries are of the multi-drain design, but there are some manufacturers that offer both "low-drain" and "high-drain" silver-oxide SR57/SR927/SR927SW batteries (again: "low-drain" batteries are labeled as 395/SR927SW batteries and "high-drain" batteries are labeled as 399/SR927W batteries). On the other hand, some manufacturers label their SR57/LR57 batteries as "395/399 batteries" to emphasize that their batteries are of a "multi-drain" (MD) design. some manufacturers label their low-drain SR57/LR57 batteries as "395 batteries" or "SR927SW" and their "high-drain" SR57/LR57 batteries as "399 batteries" and "SR927W batteries". However, AG7 and SG7 are both often used for silver-oxide batteries, while AG7 is mostly used only for alkaline batteries - for short, manufacturers often label their silver-oxide batteries as 'SG7' and 'AG7 equivalents', despite slight voltage difference between these two chemistries.Īlso, some manufacturers use their own labels, for example, Duracell D395/D399 batteries. When looking for a replacement battery, note that some manufacturers interchangeably use the same labels for both alkaline and silver-oxide batteries.įor example, the AG7 battery should be an 'Alkaline G7' (AG7) battery, and the SG7 battery should be a 'Silver G7' (SG7) battery. SR927SW/399 batteries are button/coin cell batteries featuring physical dimensions of (Diameter x Length) 9.5 x 2.6 mm (0.374 x 0.102 inches), and they are manufactured as either alkaline or silver-oxide batteries. SR927SW/395 Batteries Features and SpecificationsĬommon names/labels of these batteries include SR57, LR57, 395, 399, SR927W, SR927SW, SR927PW, SR927, SR926, LR927, LR926, SG7, and AG7, although the most common ones are 395 and SR927SW - note that labels also depend on the chemistry and the manufacturer. These batteries are commonly found in small electronic and electric devices requiring reliable power sources like keychain flashlights, wrist watches, small remote controls, and similar. batteries are very popular button/coin cell non-rechargeable batteries, available in alkaline and silver-oxide chemistries and manufactured by practically all battery brands.
