1. Why they’re dangerous
Saliva lets a coin battery pass current, which burns the tissue around it. A child can seem fine for hours while the damage grows.
2. Keep spares locked away
Store new and used batteries out of sight and reach, in their original packaging. Check that remotes, scales and key fobs have a screwed or locked battery door.
3. Throw used ones out safely
A used coin battery still holds enough power to cause harm. Put tape over both sides and recycle it straight away.
4. If you think one was swallowed
Go to the emergency room right away, even if your child seems fine. Don’t make them sick and don’t wait for symptoms. Bring the battery pack if you have it.
