    Hi all,

    I think my battery is on its way out, and having searched on the internet I am a bit confused regarding which battery can replace the OEM one I currently have.

    Currently I have Original BMW Battery (filled, not AGM) with part number 61218376451.

    I have read that the battery in the convertible is some form of mass damper , so it is a "special anti-vibration" battery. Is this true? I have seen claims but nothing that actually confirms it.

    I also read in US forums that the Duralast 92R-DLG is a direct swap. In the UK, I have found the following batteries are being suggested:

    - BOSCH S5010 - 5 Year Guarantee Battery
    - F18 Varta Silver Dynamic Car Battery (which apparently is the same as the Bosch above)

    Would anyone suggest anything else?

    If the mass-damper issue is true, would the above batteries be up for the job?

    Many thanks,
    Sol

    One of the OEM for BMW batteries is Varta. Does that narrow down your decision?

    the best/cheapest place for a battery is Vauxhall main dealer. They sell Delco Premiums (GM branded), a top make brand.

    The biggest one they do for the petrol V6's is 70aH for £73 inc VAT.



    The battery damper is fixed to the car and is a tray on rubber mounts on which the battery sits.
