Just because it tested OK has nothing to do with this concern.
Each battery post is (supposed to be) sealed were it exits the case......otherwise, acid and hydrogen gas wick up the post and destroy the cables (and anything else it gets on).
If the battery is actually being overcharged it will outgas from those 2 little vent ports sticking out the side of the case (unless the installer forgot to pull the shipping plugs).
