LR44 Battery Overview

The LR44 battery is a small alkaline button cell battery with a nominal voltage of 1.5 volts. It is also known as an AG13, A76, or 357A battery, as these batteries have the same dimensions and voltage with different manufacturer codes. It is commonly used in small electronic devices such as digital thermometers, calculators, laser pointers, toys, and watches. It has a diameter of 11.6 mm and a height of 5.4 mm.

LR44 Battery Specifications:

• LR44 is a button-cell battery.

• The nominal voltage of the battery is 1.5V.

• The LR44 battery has a capacity range of 90mAh to 150mAh.

• The battery chemistry is alkaline and contains manganese dioxide (MnO2).

LR44 Battery Features:

• LR44 batteries are small, lightweight, and inexpensive.

• They have a long shelf life, typically between 2 to 5 years.

• The battery is leak-proof and can operate in temperatures ranging from -10°C to 60°C.

• LR44 batteries have a high energy density, which allows them to power electronic devices for a longer time than other battery types.

LR44 Battery Applications:

• LR44 batteries are commonly used in small electronic devices such as calculators, watches, and digital thermometers.

• They are also used in laser pointers, digital cameras, and remote controls.

• LR44 batteries are also used 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, are all small button cell batteries that have similar specifications and features, such as being alkaline batteries with a nominal voltage of 1.5V.

However, there may be some differences between these batteries that could affect 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 has the same chemical composition and electrical properties as the LR44 battery and is typically used in small electronic devices such as calculators, watches, and digital thermometers.

• A76: This is another alternative name for the LR44 battery. It has the same dimensions and electrical properties as the LR44 battery and can be used interchangeably. It is commonly 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 it may have a different shape or dimension. It is commonly used in digital thermometers.

• 303: This is an alternative name for the SR44 battery. While it has the same nominal voltage and capacity as the LR44 battery, it has a different shape and dimension due to having a 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 has 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 nominal voltage of the LR44 battery. 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.
