I forgot I left my battery in my backyard and, ofcourse, the weather decides to rain..a lot. So when I found my battery (its a manual) it looked fine but when I press the button the LED stays on even after I let go of the button. It goes off randomly anywhere from 5 seconds to 1 minute later. Is there anywhere I can dry out the battery and not harm it? I'd hate to waste money when I just bought a new battery
