Choose the right 337 battery for precise small electronics

The 337 battery, also known as SR416SW or V337, is a compact 1.55V silver oxide button cell used in watches, micro earpieces and other miniature devices that require stable, low-drain power. In this category you can find reliable options from well-known manufacturers such as Maxell, Varta, Energizer and muRata, making it easier to replace your old cell with a matching equivalent.

When searching for a replacement, always compare the code printed on your old battery or inside the device compartment. If you see 337, SR416SW, V337 or a closely related equivalent, this category is designed for you.

What does SR416SW mean?

The SR416SW marking describes the size and chemistry of the cell. It is a silver oxide battery with a nominal voltage of 1.55V, commonly selected for devices where steady voltage matters. The 337 battery is very small, so even a minor difference in height or diameter can prevent proper contact. For best results, replace it with the same code rather than with a similar-looking alkaline cell.

  • 337 is the common battery number.
  • SR416SW is a technical size and chemistry reference.
  • V337 is often used by brands such as Varta and Energizer.

Popular uses for 337 batteries

Because of its compact format, the 337 SR416SW battery is frequently used in slim wristwatches and discreet listening devices. It can also be found in selected calculators, measuring instruments, medical accessories and small electronic modules. A quality silver oxide cell helps maintain consistent performance until the battery is close to the end of its service life.

If your watch has started losing time, the display is fading, or your micro earpiece is becoming unreliable, replacing the battery is usually the first and most cost-effective step. Choose a trusted brand and handle the cell carefully during installation to avoid short circuits or contamination from fingers.

How to select the correct replacement

  1. Remove the old battery and read the code stamped on the top side.
  2. Match the code to 337, SR416SW or V337.
  3. Check that your device requires a 1.55V silver oxide button cell.
  4. Install the new battery with the correct polarity, usually marked with a plus sign.

For watches with delicate covers or seals, consider professional replacement to protect water resistance and the case mechanism. For micro earpieces, make sure the compartment is clean and the contacts are not bent before inserting the new cell.
