Justag, thanks for the reply. The battery hold down is actually made for a battery with opposing posts, which of course this one is not. So flipping it wouldn't make a difference. As for it not sitting down on the battery, it's because this battery has a ledge on both ends and won't allow it to go all the way down to the battery. When it's time for a new battery, will get one to fit the hold down, but for now.........
Still don't know how those holes on the side could be for drainage. If the liquid got to those holes, it would just run down the battery into the tray, whether the holes were there or not.
