| Is it possible to hear battery leaking? |

Hi, I was home alone today which happens very rarely lately, pandemic and consequences. So, iIt was very quiet. I heard noise like (but not exactly) beer bottle opening or something other bubbly leaking form the bottle or opening water faucet a little for a very short time. I started to look around. I found out it was wall clock making the funny noise. The liquid on the battery negative seem very fresh. Is it possible I heard battery leaking? Or, more probable is clock made dying sounds? Clock has stopped few days ago already. Battery was 0.7 volts. Veiksmi, Jānis |

These batteries are sealed, so when a seal ruptures, it is quite possible that it may make a noise - but I wouldn't expect it to be audible in anything but in a very quiet environment - and it was close by. The fact you say the liquid seems very fresh indicates the leak is recent. As I understand it, this liquid readily reacts with CO2 in the atmosphere, producing the crystalline mess we are all familiar with. |

While it *possible* you could hear gas bubbles popping as they force electrolyte past the seal if you were close enough, its far more likely you were hearing the solenoid that drives the mechanical mechanism operating erratically and ineffectively due to undervoltage. |

it is possible. i had one discharged cell that slowly started fizzing (not a native English speaker, can't find a better word) one night. i did not get up to check what's going on, as i though it was something from he neighboring apartments. i realized what it was the next day, when i saw the mess it made on my desk. |

Yes, I've heard alkaline batteries leak too. In my case it was after doing a very high current discharge, when the device had already been turned off --- and it startled me slightly since it was a subtle "pop!" of the seal giving way, followed by the fizzing/bubbling you described. I thought an electrolytic cap had vented and was looking all over the board at them, before I discovered the leaking cell. |
