I've a laptop battery that doesn't work after a water spill. I'm just wondering, how exactly does water damage a laptop battery? I know it leads to a short circuit where the negative is directly connected to the positive. But I'm curious to know more details...for example, are the individual cells destroyed too? How does this happen? Or does the water only fry the wires inside? And, is there any way to fix it (other than buying a new battery)?

btw im asking about a lithium battery

Was this battery immersed in water?

How exactly did the battery end up getting wet?

Last question, was water pouring/dripping out of the battery at all?

not immersed...but I spilled some bottled water on it...not a whole lot, maybe a few tablespoons. When I removed the battery from the laptop, it had some water drops on it, so I wiped it completely. I don't think I saw any water dripping out of the battery. There's not really any place for the water to enter the battery, other than the part where the battery connects to the laptop. Not sure what really happened, but my battery died. :thumbsup:

Try this, it might help. Take a very fine grade piece of Emory cloth and lightly run it across the battery's contacts, just enough to remove any possible oxidation from the contacts.

I also have to ask you if your laptop suffered any water damage as well. So please provide that answer.

Your problem there, might be the same thing, those contacts do have a habit of oxidizing from the water/air combination, sometimes it looks like a fine white powder. You may need to clean those contacts as well, perhaps a clean dry toothbrush will do the trick of getting at those.

Try that and let us know if your battery now accepts a charge.
