An LR44 Button Battery is a small cylindrical cell used in a wide variety of electronic devices. It is a primary battery and is non-rechargeable. It has a nominal voltage of 1.5V and a capacity of 110-130 mAh. LR44 batteries are commonly used in watches, calculators, and other similar devices.

LR44 Button Batteries are manufactured by several companies on a large scale. They are used in a wide variety of applications and are available in different chemistry systems. The most common chemistry is alkaline, although silver oxide and zinc-air versions are also available.

A LR44 Button battery is 11.6 x 5.4 mm in size and weighs 1.95 g. Its physical dimensions are a bit larger than the standard AA battery.

The size of an LR44 Button battery follows the protocol specified by the International Electrotechnical Commission (IEC) in its 60086-3 standard. The first letter denotes the type of battery and the second denotes its shape, followed by a three- or four-digit code that specifies the cell diameter in millimeters and the overall height in tenths of a millimeter.

Each package number is a two-digit code that specifies the case size, and the first digit indicates the outer diameter in whole millimeters rounded down; the last digit codes the overall height in tenths of millimeters. These codes are standardized, and there is no ambiguity about the sizes.

Many of these batteries are shrink wrapped, stacked vertically, or otherwise designed to be more resilient to vibration and shock. These batteries may have screw posts on top, labeled only for polarity, or spring terminals. These batteries are often used in film cameras, medical instruments, and dog training devices.

The majority of these batteries are made from stainless steel and have a metallic top cap. These batteries are very durable and have a long lifespan. They are very easy to replace.

Another advantage of these batteries is that they are free from toxic materials like mercury and cadmium. However, they should be kept away from children and pets to avoid possible health problems.

If a battery is swallowed, it can become very dangerous as body liquids can close the circuit between the anode and cathode, causing local electrolysis. This can release harmful chemicals and cause internal burns. Therefore, if a button or coin battery is swallowed, contact the emergency services immediately.


LR44 Button batteries are small alkaline batteries that produce 1.5 V. They are used for a variety of applications, including watches, calculators, toys, LR44 Button Battery and medical equipment. They are also popular for their low self-discharge rate and long lifespans.

The voltage of an LR44 battery depends on the device it is powering and its capacity requirements. For example, a caliper may need 1.5 V, but it is important to note that the discharge curve of an LR44 battery will drop below this voltage over time, making it less than ideal for long-term use in a caliper. Silver-oxide SR44 batteries are slightly more expensive than alkaline LR44 batteries, but they offer a much flatter discharge curve that will remain flat above 1.5 V for most of the battery’s life.

Another consideration is safety: LR44 batteries should be kept out of the reach of children and pets since they can be dangerous when swallowed or short-circuited. They may also leak out or explode if they are force discharged, overcharged, overheated, or disposed of in the fire.

In general, LR44 batteries are safe and long-lasting when properly cared for. They should be discarded only when they are no longer usable in the device they are replacing. They should be stored out of the sun and away from moisture and heat.

These batteries are available in a wide range of sizes and capacities. They are generally labeled with the letter L for alkaline or S for silver-oxide, according to IEC 60086-3 standards. They are commonly found in wristwatches, calculators, flashlights, thermometers and many other devices.

Some of these batteries have a two-digit IEC code, while others are marked with a single digit. The first digit stands for the battery’s capacity and the second digit indicates the type of chemistry.

Typically, these batteries are sold as a pack of 20. They can be used to replace standard AA or AAA batteries in electronic devices such as watches, flashlights, and other high drain equipment.

LR44 batteries can be purchased from most hardware stores and online retailers. They are inexpensive and a good value for the money. They are also environmentally friendly, since they do not contain toxic heavy metals like mercury or cadmium.
