A couple of weeks ago, I topped off the battery cells (Mercedes battery, 4-1/2 years old) with distilled water. It is POSSIBLE that I slightly (though not by much) overfilled some of the cells, but I'm usually pretty careful about such things. The caps were definitely properly tightened.

This morning I noticed that the top of the battery was wet. If I overfilled slightly, would this force the water out and account for the wetness? Or does it sound like I have a leaking battery? And if the latter, how critical is it that I replace the battery?

Thanks.
