Maxell 315 Watch Battery - 5 Pack

Mercury-Free Formula

The Maxell 315 watch battery is part of the company's SR collection of silver oxide button-type batteries. This particular button cell battery, also known as the SR716SW, is designed to power low-drain electronics.

We recommend using this non-rechargeable battery within your analog watch or calculator. The Maxell 315 features a silver oxide chemistry, which provides a stable discharge current that won't vary in voltage.


In fact, the flat discharge rate of a silver oxide battery is designed to provide the same voltage level until the end of the battery's life. Alkaline batteries, on the other hand, offer a more slopped discharge characteristic that lowers the voltage over time, therefore lowering your electronics' performance as well.

This is why it is important to replace silver oxide button cell with batteries of the same chemistry so that your devices' maintain optimal efficiency.

Maxell is a leading manufacturer of specialty button cell batteries industry, including the 315 watch battery. These non-rechargeable batteries offer a stable operating voltage in a safe package that won't leak or damage your devices.

In addition to being safe and reliable, Maxell button cell batteries are free of mercury and therefore have less of a detrimental impact on the environment. Please note that the Maxell 315 watch battery is sold by the piece; however, the button cells are packaged in tear strips of five units. 

The Maxell 315 watch battery is the solid choice for powering your low-drain, personal electronics.
