Button batteries , also known as coin batteries, are used to charge devices that have a longer shelf-life, like a watch or the key to your car. They’re small, flat and round.
Button batteries can be found in many places around your home:
- Remote controls.
- Thermometers.
- Games and toys.
- Hearing aids.
- Calculators.
- Bathroom scales.
- Key fobs.
- Watches and electronic jewelry.
But toys aren’t always fun and games, especially battery-operated toys. Button batteries are small, coin-shaped batteries found in watches, toys, remote controls, calculators and other small electronic devices. Because they are shiny, infants, toddlers and preschoolers may want to put them in their mouths.
Lithium coin-sized and smaller batteries, often referred to as button batteries, are commonly found in many household electronics – including toys, watches, cameras, games, hearing aids, and even singing or flashing greeting cards.
It can happen as quickly as one hour after being swallowed. A button battery can cause damage in three ways: First, it can create electrical current. Second, it can put pressure on sensitive tissues and third, it can leak harmful chemicals from the battery. And all of these can cause burns to the throat or the stomach.
A button battery or any battery in the body can cause life-threatening injury. The most serious damage happens if your child swallows it. A battery that is stuck in the esophagus (the food pipe or tube that connects the throat to the stomach), can cause serious damage to tissue inside the body in as little as 2 hours.
Signs that your child has swallowed a button battery may include:
- A sudden onset of crying (some children may not be in pain)
- Drooling.
- Decreased eating or drinking.
- Difficulty swallowing.
- Hoarse voice.
- Vomiting.
- Chest pain or discomfort.
- Abdominal pain, blood in saliva and stool.
Button cells are used to power small portable electronics devices such as wrist watches and pocket calculators. Wider variants are usually called coin cells. Devices using button cells are usually designed around a cell giving a long service life, typically well over a year in continuous use in a wristwatch.
Almost all deaths involving button batteries have been associated with oesophageal lodgement and erosion into the aorta (the main artery leading from the heart) or other large vessels, with subsequent massive haemorrhage.
Main cause of button battery injuries
Often, parents don’t realise an item contains a button battery as the batteries are usually already installed.If a button battery is swallowed, it can burn through the oesophagus (swallowing tube) in just two hours, causing internal burns, severe bleeding or death.
Coin lithium batteries. You may know them as button batteries. These little silver-colored batteries power everything from toys and electronics to watches and musical greeting cards.
Lithium button batteries can react with different size button batteries, and they can also react with other battery chemistries. The bigger the battery the easier it will overload a button battery and cause it to burst.
It depends on the battery type: Zinc air: 2 years (after production) Alkaline button: 3 years (after production) Silver Oxide: 3 years (after production)
In December 2020, the Australian Government introduced new mandatory standards for button and coin batteries to reduce the risk of death and injury associated with the use of button and coin batteries.
What happens if a child licks a battery?
If the child has licked a leaking battery that has white crystals, contact the Poison Centre immediately. If the conductive fluid is still in liquid form at the time of contact, then you are advised to go to the hospital or your doctor immediately.
What happens if a child chews on a battery?
In addition to the risks of internal burns and choking, batteries pose other risks. For example, chewing on batteries can cause: severe burns in the mouth, it’s also possible that battery acid.
The button cell batteries differ according to their chemical composition, voltage capacity, ability to charge, and sizes. In this category, alkaline batteries have the same sizes as others but offer less capacity and less constant voltage than the costly silver oxide and lithium cells.
Can I replace a cr2032h with a CR2032?
It also refers to the battery’s discharge rate. In this case, the “H” refers to a high discharge rate. The CR2032 also comes in medium (M) and low (L) discharge varieties. I would replace it with the H version even if the price was 3 times as much.
Button cells are available in the same size under different manufacturer specific names. 1.5V cells are available as alkaline batteries or as more expensive but more durable silver oxide batteries. The alkaline and silver oxide batteries used to have different names.
That’s because the button-sized devices, if swallowed, could become lodged in the esophagus and cause a potentially dangerous injury due to a chemical reaction between the esophagus lining and the battery’s remaining current.
Can a toddler swallow AA battery?
Lithium and alkaline batteries
Regular, alkaline batteries are also extremely dangerous if swallowed, but that’s less likely because of their larger size. If your child swallows any type of battery, this is considered an emergency and you should immediately take your child to a hospital emergency department.
