Any way to protect my battery from water/mud on ’13 sportsman 500

So i’ve had this issue of my speedometer backlight being on and none of the numbers or anything will show, even when the key is off. This is always have i’ve been in mud or some water like on our duck lease. Usually once i clean off the battery terminals and let it sit overnight it is fine the next day. Is there any suggestions of some kind of cover or something i can put around my battery to keep mud and water from splashing up on it? Kind of a dumb location for it right in the wheel well.
