LR41 Battery Equivalent: Features, and Applications (2024 Updated)

LR41 batteries are commonly used in various electronic devices because they are small but powerful. Watches, calculators, medical devices, and toys use the LR41 for its compact size and reliable performance. It can be crucial, however, to find an equivalent battery when replacing an LR41 battery in order to ensure compatibility and efficiency. Our updated 2024 guide will provide you with comprehensive information about the LR41 battery, including its features, applications, and equivalents, so your gadgets can function at their best.

What is LR41 Battery?

There are numerous compact electronic devices that use the LR41 battery, a small, button-cell type. The alkaline battery typically has a capacity of 25-32 mAh and a nominal voltage of 1.5 volts, making it ideal for low-drain devices. As a result of its compact size, typically 7.9mm in diameter and 3.6mm in height, it's commonly used in wristwatches, calculators, thermometers, laser pointers, and small toys as well as many other applications.

In addition to being cost-effective and readily available, the LR41 battery has other advantages. It is easy to replace depleted cells with these batteries since they are available in stores and online. The output voltage of medical devices must be maintained throughout their lifespan in order to function precisely. When used in high-drain applications, the LR41 battery may need to be replaced more frequently due to its limited shelf life and capacity.

LR41 Battery Equivalent

In various devices, the LR41 battery can be replaced with several equivalent types. Compatibility with LR41 batteries is ensured by these equivalent batteries, which have similar dimensions, voltage ratings, and capacities. LR41 batteries are equivalent to the following:

Silver Oxide Batteries

SR41: Similarly sized and voltaged to the LR41 silver oxide battery, the 392, SR41W, or SR736SW offer a similar discharge curve. But they are typically longer lasting and offer a more stable discharge curve.

Alkaline Batteries

AG3: LR41 batteries are also referred to as LR736, 192, or L736 batteries. Despite its smaller size and similar voltage (1.5V), it is an alkaline battery.

192: In small electronic devices, the LR41 is often called this alternative name.

Zinc-Air Batteries

ZA675: Since zinc-air batteries have a similar size and voltage to LR41, they can sometimes be used in certain applications as a substitute for LR41, but their shelf life is greatly reduced once they are operated.
