The short version

Button batteries are in remotes, toys, watches, flashlights and hearing aids. If a child swallows one, it can burn through tissue fast. Health Canada says hundreds of Canadian children are seriously hurt every year.

The evidence

Health Canada warns that a swallowed button battery can cause severe internal chemical burns in as little as 2 hours, which can lead to serious injury or death. Toddlers are most at risk, and used batteries are still dangerous.[1]
