Why do batteries leak white stuff?

In general, though, the potassium hydroxide reaches the open air and reacts with carbon dioxide to form potassium carbonate—that white powder that cakes on the battery’s shell.

Why do Duracell batteries leak so much?

Potassium hydroxide can cause chemical burns and other health problems if exposed to the skin, mouth, or eyes.

Do batteries still work if they leak?

After normal use, a battery should not leak. The cell is strong enough to withstand built up gases inside. Leakage happens when a battery is left in a device for too long, especially when it’s not used. As that device is left unused, it still periodically ‘checks’ for the remaining power.

Are leaking batteries dangerous?

Battery leakage (commonly known as battery acid) is nasty, corrosive stuff – it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into. … For lead batteries, sulfuric acid is the dangerous residue, which requires a different type of clean-up.
