Hearing aid batteries:
Zinc-air button batteries use highly caustic potassium hydroxide as the electrolyte, which causes severe burns when exposed to delicate tissue, as the batteries have vent holes in them to extract oxygen from the atmosphere to use as part of... the battery chemistry.
In fact, the 24/7 National Button Battery Hotline (202-625-3333) was established over 20 years ago by the industry specifically for cases like these. It's also the reason why hearing aids have tamper-proof battery compartments, to keep kiddies out.
