Battery consumption symptoms involve vomiting, abdominal pain, fever, diarrhea, respiratory distress and dysphagia or difficulty swallowing. This makes it especially hard to diagnose what the problem is, especially if the caregiver didn’t see the child consume the battery.
What makes the small items so dangerous, however, is that in just two hours time they can cause serious burns from the chemical hydroxide. They can also leak a corrosive chemical called alkaline electrolyte. Researchers identified the 3-volt lithium, coin-size batteries that are less than or equal to 20 mm as the most common culprit.
