If you find that your alkaline batteries are leaking, there are a few things you can do to clean up the mess and prevent further damage.

How does an alkaline battery work?

First look at the internal structure diagram of the alkaline battery: How Does an Alkaline Battery Work ? -Let's take a look at the basic ingredients in alkaline batteries: -From the perspective of the composition of alkaline batteries, the main components of the liquid from the leakage of alkaline batteries are potassium hydroxide and water.

Why do Batteries leak?

The “alkaline” of the battery is potassium hydroxide. It's the alkali equivalent of acid's hydrochloric acid. This will leak out, forming a white “fluff” of potassium carbonate. It typically leaks on the negative end of the battery cell. Why? Apparently the positive end is vented better.

What happens if you mix alkaline and lithium batteries?
