Focuseparts Coin & Button Cell Batteries

What Is a Coin & Button Cell Battery? The simplest way to describe them is as a tiny battery with a voltage and a battery size. Coin & button cell batteries are commonly used in cameras, calculators, and many other small electronic devices. They are small, lightweight, and inexpensive and are commonly available in packs of one or more. But they are not without risk!

Symptoms of button cell ingestion

Symptoms of button cell ingestion are not always obvious, but can include acute airway obstruction, drooling, difficulty swallowing, and chest pain. However, if you suspect that a child has swallowed a button battery, you should visit the nearest emergency room immediately. Other symptoms include coughing, decreased appetite, and reduced appetite.

The biggest risk from button cells is the battery being swallowed by a small child. Even when removed from the device, these batteries still contain a strong electrical current. In two hours, a child can suffer severe burns, requiring several surgeries and possibly life-threatening organ damage. Sadly, button cell ingestion can even result in death, and this paper presents an actual case study that shows how these batteries are dangerous.

Ingestion of a button cell battery can cause mucosal burns and perforations. The battery can also cause a tracheo-esophageal fistula, which can result in major bleeding and death. Ingestion of button cell batteries is a very common problem, particularly in India. However, R Banerjee and his colleagues found that ingestion of coin & button cell batteries can lead to severe burns to the throat, mouth, and tongue.

Often mistaken for a swallowed coin, button cell ingestion can be fatal in less than two hours. To reduce the risk of this serious injury, you should take your child to the emergency room immediately. Make sure your child does not eat anything while he is being treated for button cell ingestion. If a child does, they should not eat or drink anything.


Coin & button cell batteries are single-cell, disposable electrochemical energy storage devices. Their size ranges from five to twenty-five millimeters in diameter and one to six millimeters in height. The basic functions of a coin cell include powering small portable electronics. For example, button cell batteries are used to power laser pointers, pocket calculators, and other similar items. These batteries can also be used to power implantable defibrillators and artificial cardiac pacemakers.

The lithium-ion coin cell battery uses an organic electrolyte to enhance leakage resistance. Compared to alkaline button cells, it offers twice as much voltage. It is a user-replaceable battery, and it is recognized by the UL. Its structure allows it to operate over a wide temperature range. It is made of manganese dioxide, which has better leakage resistance than alkaline batteries.

While lithium-ion coin-cell batteries are smaller and more powerful than button-cell batteries, they present a significant risk to young children. They are easy to swallow, which can lead to severe injury or death. Furthermore, the lithium-ion battery's hydroxide content can cause burns and tissue damage. Fortunately, most battery-related injuries occur in children under the age of four.


Button and coin cell batteries are the most common types of batteries. They have varying voltages, but are widely used in small devices and small-scale projects. Button cell batteries are not rechargeable and are typically used in remote controls, electronic tea lights, and other small, disposable devices. The anode and cathode materials for coin and button cell batteries are zinc, lithium, and manganese dioxide. Historically, button cells were made of mercury oxide, but these are not widely used due to the mercury toxicity.

Button and coin cell batteries are similar in design, with button cells being wider than coin cells. They are both small and flat, with diameters between 5 and 25mm. The bottom part is usually made of stainless steel while the top is typically made of metallic material. Button cell batteries are commonly used in small portable electronic devices such as wristwatches and watches. However, they are not the most environmentally friendly options.

In China, coin and button cell batteries are referred to as AG or alkaline zinc-manganese. The IEC standard uses the letter "L" and two digits to identify them. For example, LIR3032 is a 3.6V lithium-ion battery, while LIR2032 is a 20mm diameter, 3.2mm height battery.


Coin & button cell batteries are circular-shaped, metal-coated battery packs that power various household items. They are typically sold in packs of four or more. Whether you're looking for a replacement battery pack for your own vehicle, you'll find a coin & button cell battery in a package. This size is common for many different electronic products and is also known as a button cell battery.

The first thing you need to understand about coin and button cell batteries is their sizes. They are often referred to as 'coin' batteries. Their size is often defined by their voltage and their shape. These cells usually have a diameter of about five to twenty-five millimeters and a diameter of about 3.2mm. Listed below are their dimensions:

One of the key differences between button and coin cells is the size. Button cells are smaller than coin cells and have a higher voltage. Many uses for coin and button cells include key fobs, flameless candles, and scales. The size of these batteries is about the size of a nickel. If you accidentally swallow one of these batteries, the chemical reaction can damage your esophagus.

Symptoms of lithium coin cell ingestion

The symptoms of lithium coin cell ingestion are almost nonexistent. In some cases, the symptoms are similar to common infections, making proper evaluation difficult. However, there are some signs to watch for. These include: (a) a change in the child's bowel movements. If the child continues to have vomiting and diarrhea, he or she may have swallowed a button battery. The battery may be lodged deep within the body and lead to the formation of a rash.

Children over 12 months of age can safely ingest liquids, such as honey. A small amount of honey can be given six times a day to stop vomiting. In most cases, if a child vomits up the dose, it is not recommended that another dose be given. Rather, the child should be taken to a hospital or other medical facility. If these measures fail, lithium coin cell ingestion is likely the cause of the symptoms.

Fortunately, the majority of batteries will pass through the digestive tract easily and naturally. The exception is when a disk battery lodges in an internal organ. In these cases, removal of the battery is imperative to avoid complications. But if the battery is large enough, or is lodged in a narrow part of the esophagus, it is important to remove it as soon as possible. This procedure is not painful, and it can be a life-saving procedure.

Mercury content

While regular alkaline batteries are no longer made with mercury, button cell batteries still contain the metal. Despite being known to pose a choking hazard, these batteries should never be disposed of in regular trash. Instead, they should be placed in a child-proof container and properly disposed of. If you have no idea how to dispose of your batteries, contact your local solid waste district or mercury recycling facility to learn how to safely and responsibly dispose of them.

During the Second World War, mercury batteries became a common source of power in portable electronics. However, since they contain mercury, the environmental and health impacts of using these batteries have led to their ban in many countries. In addition to the dangers of mercury, the heavy metal has been banned in many countries, and regulations have been passed by the IEC and ANSI to eliminate the use of mercury in button and coin cell batteries.

Although button and coin cell batteries contain mercury, they pose no health risk when properly disposed of. In fact, they can be harmful to children if they are not properly stored. Mercury-containing button and coin cell batteries contain only trace amounts of the metal. Mercury-containing button cells should never be disposed of with other household waste. They are best disposed of properly - in their original packaging.
