Energizer 379 (SR521SW) Silver Oxide Battery (Pack of 5)

Product Information

A Silver-Oxide battery, the SR626SW has a nominal 1.55 v, cutoff volt of 1.2 v, nominal capacity of 25-30 mAh. 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.

Because of technological advancements, most manufacturers now provide so-called multi-drain SR626SW batteries, which have a big capacity and a high tolerance for high-drain currents. The SR626SW batteries’ real capacity is additionally affected by the device, maximum and average drain current, battery temperature, age, and other factors.

The SR626W and SR626SW batteries are replaced by the 377 button battery. The Energizer 377/376 is a multi-drain silver oxide button cell battery with a voltage of 1.55 volts. 377 376 is a watch battery that replaces the SR626W and SR626SW batteries. Is it possible to use LR626 as SR626SW battery equivalent? In addition, the battery employs cutting-edge multi-drain technology. Multi-drain means they are adaptable and function as well in high-drain settings (digital, electric watches) as well as low-drain scenarios (analogue watches). When multiple sizes of batteries are required, this means you just need one battery. This battery can be used to replace both 377 and 376 batteries. It has a long shelf life and has been well tested, so you can trust it. LR626 batteries are also known as AG4 batteries, LR66 batteries, alkaline 376 batteries, alkaline 377 batteries, and others.

If the battery code below the digits does not include the letters ‘S,’ or ‘P’ the battery most likely includes electrolyte (organic). AG4 versus SG4 duracell 377 battery: SG4 to be a silver-oxide G4′ battery, whereas AG4 to be an ‘alkaline G4’ battery.

The physical dimensions of LR626 and SR626SW batteries are the same (D x H) 6.8 x 2.6 mm, with the chemistry being the only change. But, some manufacturers label AG4 (incorrect) and silver-oxide batteries with both SG4 (correct) to indicate that they are a substitute for SR626SW/SR626/LR626/SR66/LR66/SG4/AG4 batteries.
