The key is to NOT put the battery back in, or to plug it in until you are absolutely sure it is dry. If it is still wet, and you apply power, you can very easily short something out, if it didn't get shorted out in the first place.
Taking the battery cover off, and placing it in a hot dry area is your best bet. I left mine on the stove for a few days on the back right burner (NOT turned on! haha) Thats where the oven vents, and the air is moderately warm, but not hot enough to melt the plastic or anything. Good Luck!
