Water on and under batter tray / R129 SL320

    When I replaced my battery yesterday there was a lot of water on and under the tray. Right next to the tray there is clearly a pipe which removes the water from other parts of the car. The pipe end is just touching the exit hole.... This can't be right can it?

    The car is a 1998 R129 SL320.

    Thanks

    The water is likely battery acid which has come out the vent hole, the pipe should be plugged into the vent hole.
    You need to remove the battery and clean up the area with boiling water to flush the area of acid.

    My new battery is sealed... Will I still need to do this?

    Lead/acid batteries have to be vented, sealed or not, you should have a hole similar to what is in picture above, should be hidden behind a hole cover, the tube you mention in post #1 plugs into the hole.
