Auto battery automatically activates

[jefbob]

Hey all, I've got several batteries so that I'm prepared for if/when one goes bad. One of my older ones, but not the oldest does this thing where the LED won't go off once I stop drawing on it. It eventually blinks a few times as if it is timing out, then will light up again when I'm not even drawing on it just holding it in my hand. I'm using mostly CE3s, but I tested it with a carto too. Anyone ever seen this?

Yep. The likely cause is liquid inside the battery. If it's turning itself on, it is no longer safe, and should be disposed of.
Sorry for your loss.

Sounds like you are a candidate for a New battery, RIP the old one.

How does liquid get inside a sealed battery?

 

[trichman]

Autos aren't sealed like manuals. They are "drip resistant".

 

[jefbob]

Didn't know that. I figured "sealed automatic" was in fact sealed.

 

[trichman]

They can't be completely sealed as they require airflow for the auto switch to activate.

After thinking about it, that makes sense. I just hadn't really thought too much about exactly how it works.

Anyways, thanks all for your replies.
