Duracell Coin & Button Cell Batteries Composition

Before you begin to purchase Duracell Coin & Button Cell batteries, you may want to learn more about the size and composition of the cells. The package's size will indicate the cell diameter and height. The first one or two digits of the package number indicate the outer diameter of the cell in whole millimeters. The standard specifies the diameters, and initial 9 means 9.5 mm. The last two digits indicate the overall height of the battery, measured in tenths of a millimeter.

Hazards of ingestion

Several studies have documented injuries from ingesting button and coin-sized batteries. These batteries are popularly used in electronic devices and are easily lost, particularly by young children. Injuries from battery ingestion are common, with poison control centers receiving 3,500 calls annually. However, not all ingestions result in serious injuries or death. If you suspect that your child may have ingested one, call the poison control center immediately.

The number of injuries associated with button cell batteries has risen in recent years. From 1998 to 2010, more than 40,400 children were treated in ERs for battery-related injuries, with 10 percent of those injuries requiring hospitalization. The number of children hospitalized by battery-related injuries rose 2.5-fold during this period. Children aged four and younger accounted for 72% of all estimated exposures. Approximately half of all injuries involved button-type batteries, while only one percent of injuries occurred with cylindrical batteries.

In the past decade, more than three thousand children have swallowed a button cell battery, causing several serious injuries. The most recent study found that three of those children were playing with devices not intended for children. These findings have the potential to decrease the number of injuries and deaths caused by these batteries. In fact, more than three thousand children swallowed a button cell battery in 2010, according to the National Poison Control Center.

Most ingestions of button and coin cell batteries do not involve visible symptoms. However, if symptoms of ingested batteries develop, it's recommended to consult a doctor. A patient may experience chest or abdominal pain and drooling. The patient may also experience coughing, decreased appetite, and difficulty swallowing. In addition to esophageal injuries, battery ingestion may result in significant physical disabilities.


Coin and button cell batteries have different compositions. Button cells are smaller and have a lower self-discharge rate than coin cells. Their use is not limited to watches; they can also be used to power digital calipers and test instruments. These batteries are widely used in portable electronics, such as wristwatches and key fobs. Duracell Coin & Button Cell Batteries composition includes:

There are many benefits to choosing Duracell coin and button cells. These batteries provide long-lasting, reliable power. Lithium coin batteries from Duracell come in child-resistant packaging with a bitter coating and are nearly impossible to open without scissors. They are perfect for specialty devices that require long-lasting power. These batteries are safe and reliable for use in small tools and electronic devices. Whether you need a replacement button battery for your laptop or camera, you can count on Duracell for reliable power.

Duracell Coin & Button Cell batteries are composed of lithium metal. Their composition varies from brand to brand, but most use the CR convention. Other brands use the DL or ECR prefix. In either case, the CR prefix means LiMnO2 manganese dioxide. For button batteries that do not need to be recharged, the BR prefix is used instead.

There are two main types of coin and button cells. The codes on coin and button cell batteries refer to the size and chemical composition of the battery. They also indicate the height and diameter of the battery. CR2032 is a lithium battery that is 20mm in diameter and 3.2mm in height. The code is also a good indication of the size of the battery. So, when choosing Duracell coin and button cell batteries, make sure that the code matches the case size and the battery.

Service life

When it comes to convenience, Duracell Coin & Button Cell batteries make the perfect choice. With guaranteed long-lasting power and Duracell quality, they can be found in many different sizes and shapes.

Coin & Button Cell Batteries - These thin circular batteries are often used to power watches, hearing aids, key fobs, and other small electronics. Their long service life is a key advantage of these batteries, which can last for more than a year with continuous use. Likewise, button cells exhibit low self-discharge, which makes them a good choice for wristwatches. Zinc-air batteries are more expensive, but they have higher capacity per unit size.

The service life of button & coin cell batteries varies, and some models last for over twenty years. However, coin & button cell batteries are typically disposable primary cells. Their materials include zinc, silver, and lithium. Other common anode and cathode materials are manganese dioxide, cupric oxide, carbon monofluoride, and oxygen from the air. Mercury oxide button cells were used, but have since been banned due to their toxicity.

While coin and button cell batteries have a shorter service life than button cell batteries, they are still a convenient and economical option for smaller electronics. In addition to their smaller size, coin and button cells can last for many years when cared for properly. The best way to determine their life is to check the size of the coin and button cell batteries. You can also check for their service life with the manufacturer's warranty information.

Voltage stability

If you are looking for a durable battery that won't break easily, consider the durability and reliability of Duracell coin and button cells. Their chemical composition and service life are different than other battery types, so choosing the wrong one can compromise the life of the device. For example, a camera light meter needs a stable voltage and usually specifies a silver cell. Likewise, different cells of the same type are optimized for specific loads and electrolytes, which makes for a longer service life. Because of their environmental and toxicity, mercury batteries are banned in many countries.

Coin & button cell batteries use different chemistries and are useful in a variety of applications. Alkaline, lithium and silver oxide are the three main chemistries found in button & coin cells. Each chemistry has a specific application and energy needs. Ensure your batteries meet your needs by understanding their spec sheet. This will allow you to maximize the life of your battery.

The package size of coin & button cell batteries is indicated by a two or three-digit code. This code specifies the cell's diameter and height in millimeters. The first digit encodes the outer diameter of the battery in whole millimeters. For example, a battery with an initial nine would have a diameter of 9.5 mm. The second digit indicates the battery's overall height in tenths of a millimeter.

Unlike other battery types, coin & button cells are generally more durable than button ones. These batteries are used in small handheld electronics such as wristwatches. The voltage stability of Duracell coin & button cell batteries can last for more than a year with continuous use. The battery will also be much more resistant to self-discharge.
