Hi, welcome to ASN. One of the guys will be able to advise you on your battery issue. Maybe be an alternator issue. Hope you get it fixed
soon. Enjoy the forum.

Have you checked the current draw whilst the car is off to see if something is draining it? If there is something drawing current you can pull fuses one by one until you find the culprit.
