The wording of the question seems a little awkward so let me explain. A few weeks ago I was changing my wife's air filter (2003 Honda Accord). The filter housing is pretty difficult to remove without taking out the battery, so I removed the battery. When I was done with the filter, I reinstalled it. I tried turning the car on, and it worked fine.
A few days later my wife tried to start he car and it wouldnt work. I popped the hood and saw that the negative cable was unhooked from the battery. I figured I just needed to tighten the nut, so I reattached it and tightened it. The car started fine.
A few days later she complained about the same thing. I popped the hood thinking it was somehow unattached again, but to my surprise everything looked fine. I gave the negative and positive cables a light tug to see if they were loose, but they werent. I pressed down on them and they didnt seem to move. Surprisingly, her car would start after that.
Now it seems to happen daily. She has to pop the hood and press down on the positive and negative connections just to get her car to start. They are connected as tightly as possible and they really dont seem to move when I press down on them, but apparently it makes a difference.
Is this a sign that there is something wrong with the battery or did I just do a bad just of installing it? Does this sound symptomatic of anything in particular?
