2007-2012 Mercedes-Benz GL450 GL550 Auxillary Back Up Battery 000000004039 OEM For Passenger Car

Item shipped much earlier which is always nice. Great product and value for the money. Perfect fit as it is an original, this by the way is the right fit for a 2018 GLA250 if it was made in June of 2018 and on.

Worked like a charm

Very good price , fits perfectly and arrived before was scheduled, great job

Perfect for 2012 E350. Super easy to install. No more aux light.

This item got rid of the Aux Battery error on my 2020 A35. Looks very similar to my original battery (original is in the left on the photo). It arrived with 3 different instances of external casing damage on it though (see pictures), so either it was shipped like that or it wasn't packed very well and it happened in transit.

Alert from dash disappeared after the old battery was replaced with this one.

Rite size

Battery was as advertised. Showed up on time and fit perfectly in my vehicle.

Very good and real Mercedes

Received the item. It wasn’t exactly the same battery it’s working. number, the box colour was black rather than the usual blue. However it was ok to fit without any problem and it seems to be working fine.

Attention de bien choisir car chez Mercedes 2 sortes celle ci doit être mise du côté gauche chauffeur.

Rien à dire c'est exactement la même batterie qu'à l'origine qui a pour fonction de débloquer la boîte en cas de panne de batterie

Perfecta para Mercedes Clase R
