10 x Eunicell AG4 Alkaline button cell batteries - G4 LR66 LR66SW LR626 LR626SW SR626W 376 377

Product Information

These batteries are commonly found in wrist watches, calculators, and similar small electronic devices requiring a reliable power source. Both SR626SW and SR621SW batteries are silver-oxide non-rechargeable batteries suitable for powering wrist watches and other sensitive electronic devices. However, these batteries are 'small shiny objects' that may attract kids and pets, and due to their dimensions, these batteries are easily swallowed.

if the battery code after the digits contains 'S', then it is the battery with sodium hydroxide electrolyte. mm button/coin cell battery replacement for your analog or digital watch, thermometer, calculator, pager, toy, micro-LED flashlight, or similar electronic device, go for a high-quality SR626SW (376/377) battery from reputable brands which has many positive reviews. Modern LR626/SR626 batteries don't contain mercury, cadmium, and other heavy metals or dangerous toxins. As one can see, actual performances vary depending on the discharge current and temperature but also depending on the battery age.To prevent confusion and thanks to modern chemistry and battery technology, some manufacturers offer multi-drain 376/377 batteries (compatible with SR626SW batteries, of course) that feature good tolerance to high-drain pulse currents and low self-discharge rate. Although they can be found in small electronic devices including small toys, cameras and calculators, this Duracell D377/376 button cell’s most common application as a watch battery. Power products are tested to the highest standards and manufactured using high quality components to deliver outstanding performance. Also, most manufacturers of '626' batteries label their silver-oxide batteries as SR626SW to emphasize that these batteries are silver-oxide batteries for wrist watches - and if they are good for wrist watches, then they are good for other electronic devices, too.

However, although these batteries are compatible with most applications, they are not necessarily "exactly the same" batteries. However, 376 batteries feature better high-drain current tolerance, while 377 batteries feature a lower self-discharge rate. PRO TIP: If you are having a hard time determining your battery, measure the width of the battery and then the height.The 377/376 button cell is a popular manufacturer’s choice of batteries for watches, calculators, toys and talking children’s books.

Many manufacturers use their own labels for these batteries, but they also tend to add IEC and other standard codes, including short descriptions about the chemistry, nominal voltage, battery equivalents, and similar. Also, these batteries have a larger capacity providing a much longer operating time for various devices using a single battery replacement.
