there is some on the battery next to the bottle why, would that be a bad thing?
Yeah, it would be bad if a hose popped....you would lose all of your coolant and overheat the engine. I'm assuming that didn't happen since it seems you just have a small leak that's making a bit of a mess.
Since your degas is evidently still mostly full it's just a matter of tracking down the leak and fixing it.
