LR44 Battery Applications:
LR44 batteries are widely used in small electronic devices like calculators, watches, and digital thermometers.
They are also found in laser pointers, digital cameras, and remote controls.
Additionally, LR44 batteries are utilized in medical devices such as glucose meters and hearing aids.
LR44 Battery Equivalent Parts:
The LR44 battery, also known as AG13, A76, 157, 303, 357, and SR44, includes small button cell batteries with similar specifications and features, such as being alkaline batteries with a nominal voltage of 1.5V.
However, there may be differences between these batteries that could impact their compatibility with specific devices. Here are the differences between these batteries:
AG13: This is one of the most common alternative names for the LR44 battery. It shares the same chemical composition and electrical properties as the LR44 battery and is typically used in small electronic devices like calculators, watches, and digital thermometers.
A76: This is another alternative name for the LR44 battery. It matches the dimensions and electrical properties of the LR44 battery and can be used interchangeably. It is often used in small electronic devices such as key fobs, remote controls, and laser pointers.
157: This is another alternative name for the LR44 battery. It has the same nominal voltage and capacity as the LR44 battery but may have a different shape or dimension. It is commonly used in digital thermometers.
303: This is an alternative name for the SR44 battery. Although it has the same nominal voltage and capacity as the LR44 battery, it differs in shape and dimension due to its different chemistry, which is silver oxide. It is commonly used in cameras, small flashlights, and toys.
357: This is another alternative name for the SR44 battery. It shares the same chemistry and electrical properties as the SR44 battery and can be used interchangeably. It is commonly used in cameras, calculators, and watches.
SR44: This battery has a different composition and capacity compared to the LR44 battery. Instead of alkaline chemistry, it uses silver oxide chemistry. The nominal voltage of the SR44 battery is 1.55V, which is slightly higher than the LR44 battery’s nominal voltage. It is commonly used in cameras, watches, and medical devices.
While some of these alternative names may be interchangeable with the LR44 battery, it is important to check the specifications and compatibility requirements of your device before using any substitute battery.
