Wet Battery

[Jackietreehorn]

So, I had a TP battery in the pocket of my pants, and said paints ended up in the washing machine for about 10 minutes before I realized it. I fished it out and dried it off, and looking at it, the water sensor is pink all over, but I can still see the grid pretty clearly.

Anyone have any idea if this will kill the battery, be all right, possibly be bad for the phone if I was to put it in? I'm gonna let it sit for a couple of days to make sure it's completely dried out (ala if the phone had gone in too), but was looking for any input. Thanks.
