LR44 Battery: Size, Uses, Features, and Equivalents
The LR44 battery is a small round alkaline button/coin cell battery designed for low-power electronic devices. It provides nominal voltage of 1.5 volts and is known for its compact size and wide compatibility.
This lr44 battery works best for small electronics like watches, flashlight, calculators, toys, laser pen and thermometers. It won’t help if you need rechargeable coin cells or hearing aid batteries.

LR44 batteries use different chemistries, and each type has its own strengths depending on what you need it for. We also keep a large stock of semiconductors, capacitors, resistors, and ICs ready to ship.
Known for being cheap and easy to find, the LR44 is one of the most common coin cell batteries you’ll see in homes, offices, and labs.
What Is an LR44 Battery?
The LR44 is a popular button cell used in toys, remotes, watches, and calculators. Almost every major brand makes it. You’ll find LR44 batteries in different chemistries, and each one fits specific uses.
This alkaline button cell lasts a long time, has a small size, and costs little. It’s easy to find in stores because demand is high. LR44 batteries come in premium and regular types. People choose them for durability, good capacity, strong energy density, and fair pricing.
Size-wise, it’s 11.6mm wide, 5.4mm tall, and weighs about 2g. When replacing batteries, check the type, size, capacity, voltage, shelf life, and chemistry. Some devices need a steady voltage to work right. In those cases, use silver-oxide instead of LR44. If the pack says “alkaline,” it’s a standard LR44.

What Battery is Equivalent to LR44?
The LR44 battery can often be swapped with other button cells that have the same size, voltage, and chemistry. Common equivalents are A76, AG13, V13GA, GPA76, LR1154, 357, SR44 which is the silver-oxide type, and LR41. Note that LR41 is usually smaller and doesn’t hold as much power.
All these batteries are either alkaline or silver-oxide and run at 1.5V. Because of that, they usually work in the same gadgets like watches, calculators, toys, and small electronics.
Still, you should always check what battery your device actually needs. Even if the size and voltage match, compatibility isn’t guaranteed for every device.
