Last Wednesday morning I went to start my car and the battery was dead (I didn't use the car for four days prior to that). So I had the battery boosted... All was working well. Today (five days later) I took my car out in the morning, came home in the afternoon. And then when I went to take the car out again, the battery was dead... I had it boosted again but it died again when I tried to start my car again after.
Why was the mechanic not able to see that my battery needed changing? Or what caused it to drain suddenly after the check up with the mechanic?
Also, I'll be bringing my car to the mechanic first thing tomorrow. When I boost my car tomorrow, will it have enough life to get to my mechanic 15km away? Or would it be better to find an auto shop closer to me (there's an Active Green & Ross not too far, but I would prefer to bring to mechanic).
