The Alkaline LR626 battery has a a nominal capacity of 15-18 mAh, a cutoff voltage of 0.9-1.0 volts, and nominal voltage of 1.5 volts The SR626SW batteries have a shelf life of at least 3-5 years, and in some cases, much longer, depending on the brand. The Energizer 377 battery, the Seiko SB-AW battery, and the Duracell D377 battery are all comparable in size and function to the Maxell SR626SW battery. These button-cell batteries, often known as micro batteries, power timepieces and small electronics like calculators and health monitors. What watch battery has the same capacity as 377?

The Energizer 364/363 Watch Battery is a silver oxide replacement for the common watch battery sizes of 364, 363, AG1 and SR621SW. As the double numbered name suggests, this button cell battery is perfectly suited to both high drain and low drain applications and will work in watches requiring either. Made by Energizer, a brand synonymous to reliability, technology, precision, and quality, this battery will ensure that your watch will not slow down or die prematurely. Watches, calculators, blood pressure monitors, diabetes meters, hearing aids, and a variety of other electronic devices are all compatible with the Energizer 376 battery. The nominal voltage of the silver-oxide SR626SW/SR626 battery is 1.55 v. This remains rather stable when the batteries are discharged. Furthermore, such batteries hold a higher capacity, allowing for a significantly longer operation duration for several devices with just one battery replacement. The battery also uses innovative multi-drain technology. Multi-drain means they are versatile and perform equally well under high-drain situations when power requirements are high (digital, electric watches) and low-drain conditions when power requirements are low (analogue watches). This means you only need one battery when different size batteries are required. This battery replaces both 377 & 376 legacy batteries. It has a long shelf life and has been extensively tested so you know you can depend on it. High-drain SR626SW batteries are recommended for applications that demand reasonably high currents, albeit they have a smaller capacity than low-drain SR626SW batteries.SB-AW, 377, GP377, AG4, V377, D377, SR66, SR626W, SR626 Watch Battery SR626SW and comparable button cell batteries SB-AW, 377, GP377, AG4, V377, D377, SR66, SR626W, SR626 Watch Battery. What kind of battery will work with the SR621SW?

A Silver-Oxide battery, the SR626SW has a nominal 1.55 v, cutoff volt of 1.2 v, nominal capacity of 25-30 mAh. The physical dimensions of SR626SW and LR626 batteries are identical, however their chemistry and consequently their characteristics and specifications differ. To add to the confusion, some manufacturers use different names for both batteries, such as SG4, 376, 377, GA4, AG4, SR66, LR66 and so on. Safety Concerns with SR626SW and LR626 Batteries However, most manufacturers now offer SR626 batteries (multi-drain) that may be used in keychain LED torches, thermometers, analog watches, both digital and toys, and other devices. Varta V377, Toshiba SR626SW, Timex BA, Sony SR626SW, Renata 377, Panasonic SP377, Maxell SR626SW, Energizer 377, Duracell D377, Duracell 377 are all Energizer 376 battery equivalents.Note that nominal capacity is affected by the device being powered by the LR626 battery, as well as drain current, temperature, battery age, and other factors.
