    Just replaced the battery on my trusty (or is that rusty) E240 estate (210 series), and have noticed that there is no breather pipe on the battery. Battery is located under the rear seat and there would appear to be a hole for it to go out off in the floor. Should it have one, if so, where can I obtain it. Thanks for looking

    Yes, there should be a pipe. Best bet is to get one from your dealer or, maybe, a scrapyard.

    Ideally you should have a battery breather pipe.
    However these days voltage regulation is much better than it used to be, batteries are better designed, and there will be little chance of gas produced, and even less chance of acid mist.
    The exception to that would be if your regulator failed and your car started overcharging.

    Personally as it's an older car, I would leave it until I was next in Halfords, and get some washer tubing which should do the trick.

    My 210 estate has a battery breather tube going through the floor, but the top end of the tube isn't connected to anything. The battery itself doesn't have a place to connect it to.

    Is the tube meant to be venting the space around the battery?
    Or
    Do some batteries have a vent point, to which the tube should be attached?

    The battery vent hole may be ot the end or side of battery and concealed behind a blanking cover.
    Does your vent tube have a 90 degree plug so as to plug the tub into the battery?

    Hi Dec,
    Thanks for your detailed reply.

    My tube does not have an elbow on the end and i cannot see a hole in the battery. That does not mean that the battery does not have a vent, because it may be hidden on the far side of the battery where I can't see.
