About button batteries
If swallowed, a button battery can become stuck in a child’s throat and result in catastrophic injuries and even death. Insertion of button batteries into body orifices such as ears and noses can also lead to significant injuries. Keep new and used button batteries out of sight and out of reach of children at all times.
Button batteries are used in a broad range of consumer and household products including remote controls, watches, computers, cameras, calculators, torches, flameless candles, fitness devices, digital kitchen and bathroom scales, musical greeting cards, and home medical devices.
Many children’s toys are powered by or use button batteries to produce light and sound effects, including plush toys, toy cars, digital pets, early learning watches, light-up yo-yos, games, novelty items and singing Santas.
Four mandatory standards have been introduced for button batteries and products containing button batteries to reduce the risk of death and injury associated with their use. For more information, see our safety investigation page.
Risks and injuries
In Australia, one child a month is seriously injured after swallowing or inserting a button battery, with some of them sustaining lifelong injuries. In Australia and globally, there is a growing record of injuries and deaths from button batteries.
Button batteries pose a severe injury risk, particularly in children aged 0–5 years. Young children are at the greatest risk due to their narrower oesophagus and tendency to place small objects into their mouths, ears and noses.
The safety risk to children from button batteries arises when they can get access to the batteries. Children can access button batteries in a variety of ways, including:
- products with battery compartments that are not secure
- button battery packaging that is not child resistant
- poor quality products which release button batteries when dropped or broken
- spare batteries being provided loose in product packaging
- spare batteries not being kept out of reach around the home
- used batteries not being properly disposed of.
If swallowed, coin-sized button batteries can lodge in a child’s oesophagus. An electrical current is immediately triggered by saliva, which causes a chemical reaction that can cause severe burns to the child’s oesophagus and internal organs such as vital arteries, lungs, heart, larynx and spine. Serious injury can occur in as little as two hours and the results can be fatal.
Once burning begins, damage can continue even after the battery is removed from the body. Repairing the damage can be painful and may require multiple surgeries over many years. This can result in ongoing treatment and follow-up plans for injuries sustained from button battery ingestion.
- If buying a toy, household device or novelty item, look for products that do not use button batteries at all.
- Look for products that are powered by other types of batteries which are less likely to be swallowed by young children and do not present the same degree of danger if they are.
- Alternatively, look for products where the battery does not need to be replaced, such as where the product is rechargeable
- If you do buy button-battery-operated products, look for ones with a child-resistant battery compartment. This will make it much more difficult for a young child to access the battery.
- Buy new button batteries in child-resistant packaging – that is, the packaging needs to be opened with scissors.
Secure button batteries
- Examine products and make sure the compartment that houses the button battery in a product is child-resistant, such as being secured with a screw, so that the product does not release the battery and it is difficult for a young child to access the battery.
- A number of products, particularly those purchased from overseas sellers or suppliers, may not be child-resistant, so be sure to check that the product you're after is as safe and secure as it can be — even if it means spending a few dollars more.
- Even if secure, button battery compartments are not necessarily child-proof. If the product in question is damaged or broken, the button battery inside can come loose. If the product is damaged or the button battery compartment does not close securely, stop using the product and keep it away from children.
Store button batteries out of reach of children
- Keep new and used button batteries out of sight and out of reach of young children at all times.
- Keep spare button batteries locked away where it is difficult for children to reach them — lock boxes, secure cupboards or high spaces are perfect for this.
Safely replace and dispose of button batteries immediately
- Old or spent button batteries can still pose a threat, so safely dispose of them immediately.
- Change button batteries on a flat surface, away from children, to avoid them rolling into places children can reach.
- As soon as you have finished using a button battery, put sticky tape around both sides of it. This will make it harder for children to swallow the button battery and avoid the risk of the battery catching fire.
- Dispose of button batteries immediately in an outside bin, out of reach of children, or recycle using a child resistant container.
What to do in an emergency
Prompt action is critical. Do not wait for symptoms to develop.
Not every health facility can manage injuries due to button batteries. Availability of care depends on where you live. The Poisons Information Centre can direct you to an appropriate medical facility that can manage the injury.
Do not let the child eat or drink and do not induce vomiting.
Remember, children are often unable to effectively communicate that they have swallowed or inserted a button battery. There may be none of the symptoms below. If you suspect a child has swallowed or inserted a button battery, then ask for an X-ray from a hospital emergency department to make sure.
Symptoms to watch out for include:
- gagging or choking
- chest pain (this may present as grunting)
- coughing or noisy breathing
- unexplained vomiting or food refusal
- bleeding from the gut — black or red vomit or bowel motions
- nose bleeds — sometimes this can be blood vomited through the nose
- unexplained fever
- abdominal pain
- general discomfort
- spitting blood or blood-stained saliva
- bloody discharge from ear or nose.
Mandatory safety and information standards
There are four mandatory standards for button batteries and products containing button batteries.
Consumer Goods (Products Containing Button/Coin Batteries) Safety Standard
This mandatory standard prescribes design and testing requirements for all consumer goods containing button batteries, including storage containers and organisers, and accessories of consumer goods, such as remote controls that contain button batteries.
Consumer Goods (Products Containing Button/Coin Batteries) Information Standard
This mandatory standard prescribes warning requirements and best practice recommendations for consumer goods containing button batteries, including storage containers and organisers, and accessories of consumer goods, such as remote controls that contain button batteries.
Consumer Goods (Button/Coin Batteries) Safety Standard
This mandatory standard prescribes child-resistant packaging requirements for button batteries, based on their risk profile, to reduce the risk of death or serious injury from children accessing batteries directly from packaging.
Consumer Goods (Button/Coin Batteries) Information Standard
This mandatory standard prescribes warning requirements and best practice recommendations for button battery packaging and button batteries themselves. Button battery packaging refers to all types of packaging or containers used when supplying button batteries.
Mandatory safety standard for toys
The mandatory standard for toys for children up to and including 36 months of age currently prescribes requirements for the design and construction of toys for children up to and including 36 months.
This mandatory standard includes specific requirements for secure battery compartments on toys that contain button batteries.
In November 2019, the ACCC consulted on the mandatory toy standard and intends to update it to align with other products containing button batteries.
