LR44 batteries are one of the most common types of button cell batteries used in many electronic devices. They are often found in watches, toys, calculators, and laser pointers. They are non-rechargeable and will last between 50 and 200 hours when used in most applications. They come in a variety of chemistries, so be sure to check the battery’s specifications before making a purchase.

The size of an LR44 battery is 11.6 mm in diameter and 5.4 mm in height. These batteries are 1.5-volt alkaline batteries that have a capacity of 110 mAh. They can be purchased from a variety of sources, including online retailers and local hardware stores.

They are sold in packs of 10 or 20. Most manufacturers label their packages as ‘kids and pet safe’, which is a good thing. However, it is important to keep in mind that small batteries are shiny and can look tempting to children and pets.

A typical LR44 battery is marked with a two-digit code that indicates the battery’s exterior dimensions in millimeters. The code also includes a description of the battery’s internal construction, such as “shrink wrapped” or “spring terminals.”

If you’re looking for a replacement for an LR44 battery, it’s worth comparing its chemistry to other equivalents to find the best match. You can do this by looking at the product’s specifications and reading customer reviews.

As a general rule, silver oxide LR44 batteries are recommended for most devices because they have a LR44 Button Battery higher capacity and a longer lifespan than alkaline LR44 batteries. However, you should consider the price and application of your device before deciding on a battery chemistry.

Depending on the manufacturer, LR44 batteries are called AG13 or 357 batteries. These are alkaline and silver oxide chemistries, respectively, but they’re actually similar to each other in some ways. In fact, they can even be stacked together to form a 4LR44/4SR44 battery pack. They have a nominal voltage of 3.1 volts for alkaline LR44 batteries and 3.0 volts for silver-oxide SR44/357 batteries, with a typical capacity in the 110-150 mAh range (for alkaline LR44 batteries). If you need to replace a battery in a device that requires an accurate voltage and power output, choose a silver-oxide SR44/357 battery from a reputable company with good reviews.


A battery of this type is commonly used in a wide variety of products, including calculators, thermometers, electronic toys, small radios and cameras. LR44 Button batteries provide excellent storage capacity, high performance, and reliability in these products.

The voltage of an LR44 battery is 1.55 Volts. This is a relatively high voltage for a button cell battery, and it is the reason why this battery is a popular choice in many devices.

Its chemistry is alkaline, and it does not contain mercury or other heavy metals like cadmium. It is non-toxic and can be disposed of in the same way as other waste.

However, if you do not want to use a LR44 battery for any reason, you can try using another similar battery, such as the Duracell 76A, Energizer A76, or AG13. These are direct replacements for the LR44 battery and can be interchanged with one another without a problem.

Silver oxide batteries are also available, but they do not produce the same amount of voltage as LR44 batteries. Instead, they have a higher discharge rate that results in a lower voltage after discharge. This means that they may not work as well in applications requiring a certain voltage, such as watches and medical instruments.

This is because the silver oxide chemistry does not retain its charge as well. This is why the battery will eventually die and need to be replaced.

In addition, silver oxide batteries are heavier than alkaline ones. This is a disadvantage in some cases, especially if you are using the battery in a device that requires a lot of weight.

Another advantage of the LR44 battery is that it is a great choice for low-drain devices. It is a good choice for small tools that require a lower voltage, like calculators and flashlights. It can also be a good option for a lighted fishing bobber. Despite the fact that these batteries have a lower voltage than lithium batteries, they can still endure for a long time when in use and are easy to dispose of as normal waste.


Button batteries or coin cell batteries are commonly used to power a variety of devices. They are usually thin and circular and can be found in a wide range of electronic gadgets, such as watches, key fobs, digital calipers, flashlights, and test instruments. They have low self-discharge, so they hold their charge for a long time when not in use.

LR44 Button Batteries are dry alkaline cells that create power by a chemical reaction of zinc and manganese oxide. They are less potent than lithium batteries, which are used in many small devices. Lithium batteries are more powerful, but they also have a high self-discharge rate. They can be more hazardous to the environment and health, and should be disposed of properly.

Lithium batteries contain metal or compounds that produce energy by a chemical reaction, and are considered to be the most common type of battery. They can be disposed of with other household waste, but they are more toxic than LR44 batteries.

As alkaline cells, LR44 batteries are non-toxic and can be safely disposed of with other household waste. However, if you are unsure of the best way to dispose of your batteries, contact your local environmental agency or government office.

The lifespan of LR44 batteries depends on the specific battery chemistry, device usage, and individual preferences. These factors can help determine which battery is better suited to your needs and budget.

For example, if you have an electronic device that requires a certain voltage to operate, a silver oxide LR44 battery will fare better than an alkaline LR44 battery. This is because the silver oxide battery will maintain its voltage longer when compared to an alkaline LR44.

If you are unsure of what type of battery is right for you, ask the manufacturer or store where you purchased LR44 Button Battery your device for advice. You can also check with the battery’s owner’s manual to learn which LR44 batteries are compatible with your device.

The LR44 battery is a popular choice because of its small size, durability, and versatility. It is made by a large number of manufacturers and sold in a variety of retailers. It is important to make sure you are purchasing a quality product from a reputable retailer.


Button batteries are small disposable primary cells that power a variety of electronic devices, such as wrist watches and calculators. They are commonly made from zinc or lithium anode materials, and manganese dioxide, silver oxide, carbon monofluoride, cupric oxide, or oxygen from the air as cathode materials.

LR44 Button Batteries are durable and long-lasting, providing reliable power and superior performance in a wide variety of applications. They are widely available and affordable, making them an ideal choice for many applications requiring high quality battery technology.

When inspecting a button battery, you might notice a 2-digit code that speaks to the case size of the battery and a 3- or 4-digit code that indicates the cell diameter and height. These codes are standardized to ensure there is no ambiguity regarding the outer diameter and height of the battery.

For example, a button battery with an initial 9 is 9.5 mm in diameter. Similarly, a battery with an initial 10 is 10.4 mm in diameter.

If a button cell or coin battery is ingested, it can burn the inside of the mouth and throat, causing painful, life-threatening injury or death. This can occur if the battery is ingested through the mouth or nose, or if it is swallowed whole.

As a reminder of the dangers of ingestion, CPSC staff recommends that product packaging for battery-containing consumer products be clearly labeled with performance and technical data about the type, chemistry, and voltage of the batteries included in the products. This information is needed to assist medical providers who encounter a battery ingestion. It can also help medical practitioners and consumers avoid hazards associated with using incompatible batteries, such as leakage, fire, and explosion hazards.

Based on CPSC staff’s review of voluntary standards related to child-resistant battery compartments for consumer products that contain button cell or coin batteries, as set forth in Table 6 and 7 above and Tab D of Staff’s NPR Briefing Package, the Commission preliminarily determines that no existing voluntary standard contains a performance requirement that eliminates or adequately reduces the risk of injury from button cell or coin battery ingestion by children age 6 or under. However, staff has found that certain elements of these standards may be helpful in meeting the requirements of Reese’s Law and the CPSA.
