When it comes to powering small electronics—from watches to toys to medical devices—the LR44 battery is one of the most common and versatile button cells out there. But what exactly is an LR44 battery, and what do you need to know before choosing one?

What Is an LR44 Battery?

The LR44 is a 1.5V alkaline button cell. It’s small, round, and highly reliable for devices that require low to moderate energy over long periods. It's frequently used in:

• Calculators

• Laser pointers

• Digital thermometers

• Children’s toys

• Small flashlights

Are There Alternatives?

Yes—LR44 has several equivalents, including AG13, A76, and 357. The difference between them often lies in the chemical composition (alkaline vs silver oxide), which can affect shelf life and discharge consistency. If you're unsure which one to use, this helpful LR44 Battery Equivalents Guide breaks it down in detail.

Key Buying Tips

• Check the chemistry: Silver oxide versions (like 357) typically last longer than alkaline ones.

• Don’t mix brands: For best performance, avoid mixing old and new batteries or different brands.

• Watch out for mislabeled products: Some sellers label LR44-equivalents interchangeably—always verify the voltage and size.
