Excuse me for my bad English
AUDI A4 B8 2009 1.8TFSI 118 kilowatts
I have a problem for about four months, no mechanic you know stym give advice. Battery lasts just a few days and then end loss through the cable. I have bought two new batteries which duty cycle or one start over the other.


When the car is completely yet fully discharged, the door opens I have a mechanical key so after starting, and about 30 minutes drive with no problems on that day torch works. But when the car at the front of the house after work and I lock it so easily discharged by night, and this became repetitive. So I stohoto conclude that the battery alternator recharges but Nicola discharged it at night. When the battery is fully charged, so it will last about a week.
I've bought two batteries one at 110Ah original audio, the other 80Ah Bosch, both of which are purely new.


ALREADY I'm really desperate ... Help
