LR44 Button Battery

LR44 Button Battery

LR44 is one of the most popular types of button cell batteries used in a wide range of devices. It can be found in watches, calculators, LED flashlights, toys, calipers, clocks, vibrators and more.

The name LR44 is derived from the battery nomenclature defined by the International Electrotechnical Commission (IEC). It represents alkaline battery chemistry.


The LR44 Button Battery is a popular and common type of battery that is used in various devices such as watches, toys, calculators, and other electronic devices. These batteries are non-rechargeable and feature a long life, high performance, and great reliability.

LR44 batteries are 11.6 mm in diameter and 5.4 mm in height. They are available in many different chemistries, including alkaline, silver oxide, and zinc-air.

These batteries are a common size found in a wide variety of devices and often come with a handy holder for them to fit into. Some of these holders have switches that can be used to switch the batteries on and off without having to remove them from the device.

Some of these batteries also have a flat side that is usually marked with a little protrusion, allowing you to easily identify which end is the positive and negative sides of the battery. This can make it easier to align the battery to its proper markings and ensure that it will operate correctly.

Most of these batteries are based on the International Electrotechnical Commission (IEC) standard 60086-3. This standard defines the battery name, shape, and dimensions.

As per this standard, the LR44 battery should be labeled as LR1154 (alkaline) or SR1154 (silver-oxide). The short two-digit code is often used instead of the full five-digit IEC number, but manufacturers add information about the chemistry, and sometimes a full four-digit code.

LR44 batteries can be replaced by other types of batteries, such as AAs or AAAs. They are typically cheaper than a single LR44 battery, and can be stacked vertically to create a larger battery pack.

Other battery types include CR11108 or CR1/3N batteries that are often used in cameras and other small devices. These batteries have LR44 Button Battery the same dimensions as two LR44/SR44/SR44SW batteries stacked vertically, but are less expensive.

Another type of battery is the Energizer 357/303 button cell, which has a similar size to an LR44, but offers more voltage and capacity. These batteries can also be used in a wide range of devices, but are primarily used in flashlights and other electronic gadgets.


Button cell batteries are used to power small devices such as hearing aids, wrist watches, and calculators. They are available in various sizes and chemistries, with the most popular being alkaline and silver oxide.

The voltage of an LR44 Button Battery is 1.5 V, which makes it ideal for many types of small electronics. These include watches, laser pointers, thermometers, medical devices, calculators, small radios, and toys.

LR44 Button batteries are made of non-toxic materials, so they’re safe for children and the environment. They are also durable, so they’ll last a long time when unused and in storage.

They’re also relatively cheap, so they’re often found in many places where other batteries are not. However, they don’t provide the same capacity or stable voltage as other types of batteries, so it’s important to choose a high-quality battery.

If you’re shopping for an LR44 battery, make sure to find a product that has a good rating and good reviews from reputable companies. You should also read the specifications to compare it against equivalent products.

Another way to find the right battery is to check its size and the type of chemistry. Most generic packages will list both AG13 and 357 on the label, but if they don’t, it’s best to look for a silver-oxide battery with a good review instead.

A typical LR44 battery measures 11.6 x 5.4 mm, while a 357 is 11.6 x 5.3 mm. In some cases, they are interchangeable – for example, a LR44 can be replaced by a 357 in a caliper.

LR44 Button Batteries are common in many different applications, including watches, cameras, thermometers, calculators, and gun sights. They’re also used in dog collars, electronic keys, and medical equipment. They are sometimes called button or coin cells. They are typically manufactured by almost all recognized companies and can be found in many stores. They’re also made from non-toxic, recyclable materials and do not contain mercury or cadmium. The batteries are designed to be long-lasting and have a low self-discharge rate, so they’ll keep their charge for a long time when unused.


LR44 Button batteries are small and compact, making them a great choice for a variety of devices. They are widely used in watches, calculators, and electronic toys. They also power low drain hardware like radios and cameras.

Unlike lithium batteries, LR44 batteries don’t release heavy metals into the soil and can be disposed of in the same manner as other trash. This makes them a safe and environmentally friendly alternative to traditional alkaline batteries, which can cause ground fill explosions or poison the air.

The capacity of an LR44 battery varies depending on the device it powers. It usually ranges from 110 mAh to 130 mAh. The higher the capacity, the longer it will last before needing replacement.

If you have a LR44 Button Battery device that uses a LR44 battery, make sure you buy the correct size for your model. Some devices have small metallic tabs that hold the battery in place and may require a special size to function.

You can find a variety of LR44 replacement batteries on the market, including Duracell 76A, Energizer A76, and AG13. These batteries have the same dimensions as an LR44, but are different in other ways.

Other LR44 replacements include CR11108 and CR1/3N batteries. These have the same dimensions as an LR44, with a slightly higher voltage and higher capacity than an LR44. They are often used in devices such as cameras, calculators, dog collars, gun sights, and PDAs.

However, they do not offer the same durability as an LR44. Generally, they have lower self-discharge rates and are less stable in voltage than an LR44. They also have a shorter life span than an LR44 and are more expensive to buy.

When shopping for an LR44 equivalent, be sure to check the type code and other markings. These will indicate whether the battery is an alkaline or silver oxide coin cell. Additionally, look for a two-digit code that indicates case size. This is often a sign that the battery is not an LR44. Moreover, the type code should be printed on the battery’s casing. If it’s not, you should not purchase the battery.


LR44 is a popular type of button battery that is used in many small devices including calculators, toys, and radios. It is a non-rechargeable and non-hazardous battery that works efficiently in both low and high temperatures.

Unlike lithium batteries, LR44 and SR44 batteries are safe to use as long as they are used in accordance with the manufacturers’ instructions and are not damaged or misplaced. However, they can cause serious injury or even death if swallowed by children or pets, and must be treated as a potential hazard.

Button/coin batteries, which can also be referred to as LR44 and SR44 batteries, operate using one of 4 chemistries: alkaline, lithium, silver oxide, and zinc-air. Each battery type has its own safety features that help reduce the risk of injuries.

A button/coin battery should always be labeled with a type code that indicates its chemistry and other important information. The most common type code is ‘LR44’ for an alkaline battery and ‘SR44’ for a silver-oxide battery, according to the IEC standard 60086-3.

In addition to the type code, LR44 and SR44 batteries should have markings on them to indicate their chemistry. The positive side of the battery should be flat and possibly have markings, while the negative side should have a small circular protrusion.

Most battery packaging includes a warning that the battery is not suitable for children. The Australian Government has introduced 4 mandatory standards to reduce the risk of death and injury from button and coin batteries. These standards apply to both new and second-hand products supplied from 22 June 2022.

Toys that contain button batteries must be securely locked in a compartment to prevent the child from being able to remove them. Toys that are not securely locked must be stored away in a safe place when not in use.

Some types of button batteries are choking hazards, which makes them dangerous to small children who may swallow them. These batteries can cause serious burns if they are pushed up their nostrils or lodged in their gullet (oesophagus).

To help minimise the risk of a button battery being ingested, ensure that all button and coin batteries have lockable compartments. If you are not sure if a toy has such a compartment, contact RoSPA for advice or use one that is not accessible through the mouth.
