Step 1: Remove the old battery so you can find a replacement. Somewhere should sell you the battery alone, even if they won't do the replacement for you.
Step 2: If you're not going to use this in a wet environment just put the new battery in and don't worry about the seals. Just be careful when you clean it. For example, use a damp cloth but don't immerse it.
Step 2b: If you really want to seal it get some silicon seal from a hardware store or maybe an outdoor store. Line the edge of the battery compartment where the cover meets the compartment and replace the cover. Let it set and you should be good.
