battery problems again okay so last week on friday morning my battery light came on for about 2 minutes and went off. it stayed off until today friday 10/12 and came back on at 7:00 am and didnt shut off. i just got a new alternator a month ago im wondering if its the battery now. the car is a ford focus se hatch with 133,100 miles on it. also the engine was cold when the light came on idk if that does anything
