9/19/2023

Have you ever seen a button-cell battery in electronic devices? It plays a crucial role in our life. However, most people never deeply explore a Cell Battery. This post will introduce some details of Cell Battery LR44 to help you choose a battery better.

 

 

What is an LR44 1.5v Battery?

 The LR44 1.5v Battery is a small, round, button-cell battery that is commonly used in a variety of electronic devices like calculators, watches, laser pointers, digital thermometers, small toys, and various other small electronic gadgets. They provide a relatively low voltage (usually around 1.5 volts) and are designed to provide a stable power source for these types of devices. It is also known by other names such as AG13, A76, 357, and several other designations depending on regional or manufacturer-specific naming conventions.

 

Understand LR44 1.5v Battery Specifications

  1. Chemistry: manganese dioxide

The LR44 1.5v Battery is an alkaline battery, which means it uses an alkaline electrolyte (usually potassium hydroxide) to generate electrical power through a chemical reaction between zinc and manganese dioxide.

 

  1. Construction: small, flat disc

The LR44 1.5v Battery is a button-cell battery, which means it is shaped like a small, flat disc. It's commonly encased in a metal jacket to protect its components.

 

  1. Voltage: 5 volts

The LR44 1.5v Battery has a nominal voltage of 1.5 volts. This voltage remains relatively stable during most of its discharge cycle.

 

  1. Capacity: 110-120(mAh)

The capacity of an LR44 1.5v Battery is typically around 110-120 milliampere-hours (mAh). This indicates how much charge the battery can deliver over time. Higher capacity means the battery can power a device for a longer duration.

 

  1. Dimensions: 6 mm (0.457 inches)

The LR44 1.5v Battery has a diameter of approximately 11.6 mm (0.457 inches) and a height of about 5.4 mm (0.213 inches). These compact dimensions make it suitable for use in small electronic devices.

 

 

Do You Know LR44 1.5v Battery Features?

 

Stable Voltage

LR44 1.5v Battery offers a relatively high energy density and stable voltage output during most of its discharge cycle.

 

Small Lightweight

LR44 1.5v Battery is small and lightweight. Its 1.5 volts voltage is suitable for a wide range of low-power electronic devices.

 

Longer lifespan

Alkaline batteries, including the LR44, have a relatively low self-discharge rate. This means they can hold their charge for an extended period when not in use, making them suitable for devices that are used infrequently.

 

Inexpensive and Widely Available:

LR44 batteries are widely available in stores that sell batteries, electronics, or general household items. They are also readily accessible online from a variety of retailers at reasonable prices.

 

Environmentally Conscious Disposal:

Like all batteries, LR44 batteries should be disposed of properly according to local regulations. They may contain potentially hazardous materials, so it's important to recycle or dispose of them in designated battery recycling facilities.

 

Common Applications of LR44 1.5v Battery

  • Many small, handheld calculators use LR44 batteries for power.
  • LR44 batteries are commonly used in quartz watches to power their timekeeping mechanisms.
  • Some laser pointers, especially smaller models, are designed to be powered by LR44 batteries.
  • LR44 batteries are frequently used in digital thermometers for accurate temperature readings.
  • Some models of hearing aids use LR44 batteries to provide power for amplification.
  • Many small electronic toys, especially those with simple electronic components, utilize LR44 batteries.
  • Certain medical devices like glucose meters and electronic thermometers may use LR44 batteries for power.
  • Some electronic key fobs for cars or access systems use LR44 batteries.
  • Some small clocks, especially those with electronic displays, may use LR44 batteries.
  • Small LED flashlights and keychain lights use LR44 batteries for illumination.

 

 

LR44 batteries Equivalent Parts: AG13, A76, 157, 303, 357, and SR44

 

LR44 1.5v Battery also can be called AG13, A76, 157, 303, 357, and SR44. All of these batteries share many of the same characteristics and attributes, such as being alkaline batteries with a nominal voltage of 1.5V.

However, there can be some variations among these batteries that might affect how well they work with particular gadgets. The variations between these batteries are as follows:

 

AG13: This is one of the LR44 1.5v Battery's most popular alternate names. It is primarily used in small electronic devices like calculators, watches, and digital thermometers and has the same chemical makeup and electrical characteristics as the LR44 1.5v Battery.

A76: Another name for the LR44 1.5v Battery is A76. It is interchangeable and has identical physical and electrical characteristics as the LR44 1.5v Battery. Small electronic gadgets like key fobs, remote controls, and laser pointers frequently employ it.

157: This is another alternative name for the LR44 1.5v Battery. It has the same nominal voltage and capacity as the LR44 1.5v 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. Although it has the same nominal voltage and capacity as an LR44 1.5v Battery, the silver oxide chemistry gives it a different form and size. It is frequently utilized in toys, small flashlights, and cameras.

357: It is interchangeable and shares the same chemistry and electrical characteristics as the SR44 battery. Watches, calculators, and cameras all frequently use it.

SR44: Compared to the LR44 1.5v Battery, this battery is different in composition and capacity. It employs silver oxide chemistry rather than alkaline chemistry. The SR44 battery's nominal voltage is 1.55V, which is a little bit higher than the LR44 1.5v Battery's nominal voltage. It is frequently utilized in timepieces, cameras, and medical equipment.

 

While some of these alternative names may be interchangeable with the LR44 1.5v Battery, it is important to check the specifications and compatibility requirements of your device before using any substitute battery.
