Is it possible to hear battery leaking?

<< < (4/5) > >>

BBBbbb:
Yup, heard it once, like described - fizzling. The alkaline AA (maybe AAA not sure now) was less than a meter from me, pretty silent in the apartment when it started and the sound persisted for at least 5 seconds, enough to get my ear close to make sure it was coming from the battery.
I was quite puzzled when it happened and was looking at the battery for the next minute or so wondering basically WTF...

On a related note, I've heard at least two different F32T8 fluorescent tubes fail in a similar manner. When one of the cathodes wears out the arc will start to wander and often strike from one of the cathode support leads instead of the tungsten coil. This heats it up and at some point it can expand to the point where it cracks the glass to metal seal and you get a soft *tink* pssssssssssssssssssssst and the light goes out. In those particular cases I just happened to be in the room at the moment that the lamp failed.

Exactly like that. English is my 3rd language, I was trying to find the right words and you nailed it, thanks!

Good point! It has been unusually hot lately here where I live, ~30*C during the day outside. Close to that level inside around the clock.

Btw, the process continues. I haven't heard the noise anymore, but there are visuals 🙂

PS Normally, a person would  throw the battery out for recycling, but it sits on my desk. Says something 😂
