Button Cell Batteries

Button Cell Batteries

RoSPA has been made aware of the dangers of children swallowing button cell batteries that can be found in toys, remote controls, calculators and small electronic devices.

What are the dangers?

Although a child may not choke, if undetected the batteries can do serious damage to the gastrointestinal system. When combined with saliva, the electrical current from the battery produces caustic soda that burns through the throat or stomach and can cause further damage to other internal organs.

How many cases have there been?

According to the National Capitol Poison Centre in the USA, there are around 3,500 incidents reported every year where swallowed batteries require urgent treatment. The Queensland Injury Surveillance Unit in Australia also estimates that four children a week are admitted to hospital after swallowing batteries.

What precautions can I take to protect my child?

  • Make sure that toys and other products using button cell batteries, such as small electronic devices, have lockable battery compartments. This should mean that they are safe for children to use as the batteries are locked away
  • Be extra vigilant with items including musical greeting cards, flameless candles and remote controls as they do not have lockable compartments. RoSPA advises that children should not be allowed to have access to these products if the battery compartment is not secure
  • It is a good idea to ensure that spare batteries are locked away, and used batteries are disposed of correctly.
