Duracell 377 SR626SW SB-AW AG4 1.55v Silver Oxide Watch Battery

Product Information

A sodium hydroxide electrolyte battery is identified by the letter ‘S’ in the battery code following the digits. 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

These batteries are small enough to be easily swallowed, and if they become lodged in the throat or digestive system, they can cause serious injury or even death. AG4 versus SG4 duracell 377 battery: SG4 to be a silver-oxide G4′ battery, whereas AG4 to be an ‘alkaline G4’ battery. To prevent this from happening, it is important to keep LR626/SR626 batteries away from sources of heat and to avoid short-circuiting them. The only difference is that Energizer is a brand name, while SR626SW is a designation used by other battery manufacturers to identify the same type of battery.Insert the new battery: Insert the new SR626SW battery into the watch with the positive (+) side facing up. It’s important to note that while these batteries have similar specifications, they may not be exact replacements for the SR626SW in all devices. AG4 batteries have a chemistry that is alkaline and should not be used as a watch battery replacement or a hearing aid battery replacement. The alkaline AG4 will not have enough capacity or continuous voltage to power these devices. An alkaline batteries voltage will slowly drop over time. It is imperative that the correct chemistry battery is used for the right application. The SR621SW has a slightly smaller diameter than the SR626SW, making it a better fit for some devices. It is also a popular choice for use in digital watches, small electronic devices, and medical equipment like blood glucose meters and hearing aids. Differences – SR626SW Battery Equivalent

The coin/button cell batteries SR626SW and LR626 are commonly found in thermometers, vehicle keys, remote controllers, digital cameras, toys, wrist watches, and other devices. A Silver-Oxide battery, the SR626SW has a nominal 1.55 v, cutoff volt of 1.2 v, nominal capacity of 25-30 mAh. Yes, the Energizer 377 and SR626SW are the same types of battery. They both have the same voltage of 1.55 volts and are used in smallish electronic gadgets such as watches, calculators, and medical devices.

The SR626SW watch battery is also known as the 377 battery, SR66, SR626 or AG4 battery. The SR626SW or 377 watch battery is one of the most widely used watch batteries. Available singly or in packs of 10 batteries for the price of 8.
