How to Use Button Cell Battery Safely?

Energizer and Safe Kids USA established a safety partnership to address this growing child safety hazard – though we need to note that injuries also are sustained by adults. They launched an effort called The Battery Controlled, committed to raising awareness of this issue and sharing information with parents to help prevent injuries. They place the burden on you to prevent this product from injuring your family. This includes:

1. Keep out of Reach 2. Get help Fast 3. Tell Others

According to studies, the major sources of ingested button cell battery for children under 6 years of age are: 1. Directly from the product-61.8% 2. Loose or sitting out-29.8% 3. Battery packaging-8.2% 4. Hearing aid containing battery-0.2%



Based on my discussions with subject matter experts at the recent Annual Meeting and Training Symposium of ICPHSO (International Consumer Product Health and Safety Organization), ingestion is only one of the ways that these coin cell batteries do harm. They are also inserted in ears, nose and eye cavities. Additionally, a significant number of adults, especially the elderly, are treated for ingestion or insertion injuries. Adults may be cognitively disabled, yet other possibilities also include scenarios in which the elderly are changing the batteries in their hearing aids–placing the new one in their mouth while removing the old (or vice versa) and then unintentionally swallowing the battery cell for any one of several reasons, such as sneezing, forgetting about the battery, etc.

Adults may be able to get treatment very fast, if they are aware of the hazard associated with lithium button cell and seek medical treatment immediately. Yet, they need to be informed of the hazard too, as it may be counter-intuitive to know that such a small, round, old (seemingly discharged) metal hearing aid battery can do material physical harm. Obviously, children and cognitively disabled adults are at far greater risk. Even if they are old enough to communicate, they may not inform a parent or caregiver of the ingestion, nor tie together the symptoms they later experience with the ingestion.

Button Cell Battery

There is a useful product in your home that can be very, very dangerous to children, and some adults, if it is ingested or inserted into an eye, nose or ear. Indeed, you may have dozens of this product in your home — in use, in storage or sitting in the grocery bag you just placed on the floor in your kitchen, waiting to be emptied. It is a button cell battery. Even though this safety hazard has appeared from time to time on TV or YouTube or in a parent’s magazine, it has been hard to get the word out. I’m asking you to help ensure that everyone learns about the hazard and protects their families.

If you have small children, or adults in your home that need supervision, such as people with autism or dementia, or if they just visit, you need to take steps now to protect them from injuries related to coin cell batteries. Got grandchildren? This post is for you, too. Here’s an example of the product on the store shelf (although they are sold in various sizes and power) and what they look like after they have been ingested:Some smaller, and seemingly innocuous, the coin cell batteries supply power and are usually tucked away in countless electronic products, such as mini remote controls, hearing aids, calculators, watches, car key fobs, bathroom scales, flameless candles and singing greeting cards.



In the U.S., it is like an epidemic. 40,000 cases of children ingesting small batteries were documented between 1997 and 2010. 14 of these resulted in death. The number of cases resulting in serious injury or death has more than quadrupled in the past five years and will continue to increase at an alarming rate as more electronics integrate coin cell batteries into their design.

When these coin cell batteries (sometimes referred to as button cell batteries) are swallowed, the resulting injuries can be severe enough to cause lifelong injuries or death. These are not just little metal coins that may be pooped out like a shiny new dime. They can and do get stuck. They are electrical and remain so even when they are ready to be replaced in your remote control. A life threatening process starts the moment the battery cell interacts with saliva or other mucous membranes. An electrical current forms around the outside of the battery, generating an alkaline hydroxide that eats through mucous membranes — FAST.

On average, through 2010, one battery-related emergency room visit occurred every 2.66 hours in the U.S. Unfortunately, symptoms of a carbon zinc batteries ingestion are not unique and may be similar to other childhood illnesses, such as coughing, drooling and discomfort. This only complicates the matter, leading to greater injuries. A single 3V lithium battery can cause severe esophageal burns within 2 hours and eat a hole completely through the throat within 4 hours. So, real and permanent damage may result before the parent or caregiver has even decided to go to the emergency room.

Views of Button Cell Battery

What is Button Cell Battery?

Button cell battery is, as the name suggests, small, round, flat batteries similar in size to buttons you find on clothing; they are 5/16 of an inch in diameter, to be precise. Button cells are used to power small portable electronics devices such as wrist watches, pocket calculators, and hearing aids. Lithium cells are generally similar but somewhat larger; they tend to be called lithium cells or batteries or coin cells rather than button cells.



What is LR44 Button Cell?

A battery may consist of a single cell or two or more cells in a single package, such as the 2CR5 (two lithium cells) or a 4LR44 (four alkaline LR44 cells), or a 1604 9-volt battery which has six cells. lr44 button cell batteries produces 1.5 volts, but only retain a small amount of energy, so they are used to power items that draw very little power, such as LED displays and watches. If you have an item that uses a small amount of amount of electrical energy, but requires more than 1.5 volts, arrange your LR41 button cell batteries in series and you can increase the voltage. For example six LR41 button cells arranged in series produce 9 volts, enough to power a strip of LED lights.

Package Size of Button Cell Battery

Package size of button batteries using standard names is indicated by a two-digit code representing a standard case size, or a three- or four-digit code representing the cell diameter and height. The first one or two digits encode the outer diameter of the battery in whole millimeters, rounded down; exact diameters are specified by the standard, and there is no ambiguity, e.g., any cell with an initial "9" is 9.5 mm in diameter, no other value between 9.0 and 9.9 is used. The last two digits are the overall height in tenths of a millimeter.

Methods to Identify Button Cell Battery

Composition of button battery

Button cell is also known as button battery (button cell), in general the diameter is larger, and thickness is thinner (relative to the column battery, such as 5 AA batteries on the market). It is actually a lithium battery. Button battery has single monomer and stack distinction in accordance with the appearance, the same battery classification has columnar battery, square battery, shaped battery. More common button batteries are AG3, AG10, AG13 battery used for toys and gifts, CR2032 CMOS battery used on the computer motherboard, CR2025 used for electronic dictionary, CR2016 or SR44 type used on electronic table surface, SR626 and so on. The alphabet letters in front of button cell battery model name represents the type of battery and numbers indicate the size, the first two numbers indicate the diameter, and the latter two mean the thickness.


Button cell applications

Button batteries have been widely used in a variety of micro-electronic products due to their smaller size, the diameters range from 4.8mm to 30 mm, and thickness ranges from 1.0mm to 7.7mm; generally used as back-up power supply of all kinds of electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory card, remote control electric toys, pacemakers, electronic hearing aids counter camera.

Button battery is also divided into chemical batteries and physical battery two categories, among which chemical batteries are commonly used. They consist of (positive) anode, cathode (negative) and its electrical contact liquid. Its appearance of lr44 button cell is stainless steel material, and as a positive electrode, its negative is stainless steel round cover, and there is seal ring insulation between the positive electrode and the negative electrode, the sealing ring can also prevent leakage of the electrolyte in addition to insulation. There are many different types of button batteries, the majority are named by the materials, such as silver oxide batteries, lithium batteries, alkaline manganese batteries.

Pay attention to three aspects to identify shoddy button cell:
1. Recognize from the battery sign. They don't have trademark, no origin, no production date, no inspection certificate, which are marked with “BUTTON CELL" in English, giving the illusion of a foreign-made. 2. Recognize from the battery appearance. Most of shoddy button anode side surface is coated with yellow, giving the sense of being plated "gold". Cathode bottom of the enclosure is prone to rust spots. 3. Recognize from the battery performance. Most alkaline manganese battery capacity is low, usually less than the national standard 1.55V, short life; it is prone to leakage, corrode electrical appliances; poor voltage load characteristics, the battery discharge curve sharply slash downward; prone to flatulence, cause the battery "bosomy belly."
