Hi all, I know the cold weather is settling in, my car has all of a sudden is having issues if its left for more than 8 hours or more. I am having to bump every morning to it going, if you try and start it there is some charge there but that slowly fades, I have been fine when leaving work at night if I have been on lunch, but there was one instance where it didnt go on lunch, and when I left work that evening it wouldnt start. I know this is likely to be caused by an old battery and the colder weather, however there could also be drainage problems too. I took it to halfords as I was passing today and got them to do a free battery check on it, they attached the device to the battery, run the test, asked me to turn on my headlamps, then turn them off again, then he said that it looks like something is draining my battery. as far as I can tell there are no lights/or anything on when I lock the car - Could this still be a weak battery, or something else? Not sure where to go from here, to be perfectly honest I have never taken a car to be battery tested before, I have always found it was weak, and replaced, so not sure how accurate these tests are. Shall I just get a new battery, or get it investigated?
