LR41 Battery Equivalent: Compatible Replacements and Best Options

 The LR41 battery is a compact and widely used 1.5V alkaline button cell, found in devices like digital thermometers, watches, laser pointers, and small toys. Due to its frequent use and small size, many users often look for suitable replacements or equivalents when an LR41 is not readily available. Fortunately, several batteries match the LR41’s specifications and can be used interchangeably without harming your device.

LR41 Battery Overview

The LR41 is an alkaline battery with the following key specifications:

  • Voltage: 1.5 volts

  • Diameter: 7.9 mm

  • Height: 3.6 mm

  • Chemistry: Alkaline

  • Capacity: ~25-32 mAh

Its compact design and moderate energy capacity make it ideal for small, low-drain electronics.

Common Alkaline Equivalents

The LR41 battery is known by many different names depending on the manufacturer or region. Some of the most common equivalents include:

  • AG3

  • 192

  • L736

  • G3A

  • V36A

  • GP192

All of these batteries have the same dimensions and voltage output as the LR41, making them fully interchangeable in most applications.

Silver Oxide Alternatives

While LR41 is an alkaline battery, silver oxide versions also exist that are compatible. These batteries offer longer life, better voltage stability, and superior electronic components, especially in high-drain or sensitive devices. The most widely used silver oxide equivalents for LR41 include:

  • SR41

  • SR41W

  • 384 / 392 (depending on brand labeling)

Though slightly more expensive, silver oxide batteries are often worth the upgrade for critical devices such as medical instruments or digital watches.

When and Why to Use Equivalents

Using an equivalent battery is a practical solution when LR41 is out of stock or unavailable locally. However, choosing the right type depends on your device's power needs:

  • For low-drain devices: Alkaline replacements like AG3 or L736 are sufficient.

  • For high-drain or precision devices: Silver oxide options such as SR41 or 384 are preferred for longer performance and voltage consistency.

Always check your device’s manual or the original battery code before selecting a replacement to avoid compatibility issues.

Conclusion

The LR41 battery has a wide range of compatible equivalents, including alkaline options like AG3 and 192, and high-performance silver oxide alternatives like SR41 and 384. Knowing these equivalents helps you make informed choices when replacing your battery, ensuring your devices stay powered and functional without interruption. Whether you choose an economical alkaline cell or a long-lasting silver oxide battery, make sure the size and voltage match the original to maintain optimal performance.
