Understanding the 377 Button Battery

When I first encountered the 377 button battery, I quickly learned it’s a small, round, silver-colored battery commonly used in various devices. These batteries are often found in watches, calculators, hearing aids, and other small electronics. The 377 battery is also known as SR626SW or AG4, and understanding its specifications helped me make informed decisions.

Identifying Equivalent Models

As I researched further, I discovered that several batteries are equivalent to the 377 button battery. Familiarizing myself with these equivalents, such as the SR626SW, LR626, and AG4, was crucial for ensuring compatibility. I found that checking the voltage and chemistry was essential in selecting the right alternative.

Voltage and Chemistry Considerations

I noticed that the 377 battery typically has a voltage of 1.55V, which is important for the devices I use. The chemistry can vary, with silver oxide and alkaline being the most common.
