Button cells

The BfRshort forGerman Federal Institute for Risk Assessment assesses the health risks of button cells.

Button cells are small, flat batteries that are found in many devices: from wristwatches to remote controls and children’s toys. However, button cells can be dangerous for smaller children: if swallowed, they can get stuck in the oesophagus. Contact with the moist mucous membranes often results in a current flow that can cause severe chemical burns. In the worst case, the injuries can even be fatal. The BfRshort forGerman Federal Institute for Risk Assessment therefore advises people who suspect that e.g. their child might have swallowed a button cell to go to a paediatric hospital or emergency department immediately.
