Had the battery and alternator individually tested and replaced at the same time about a month ago. Car has been fine since then, but last night the battery was dead. After getting a jump, all the dash lights seemed dim, the windows were slow to roll up and down, headlights were dim, and the heater fan was barely going when set on four. Tried to start it after driving all the way home, and got nothing at all.

    I would check battery cables they may be loose and check ground cable to body and engine for contact. Recheck battery too.

    ther is either a draw on the battery or the battery has a bad cell test battery again then go from there. you can check for a draw by putting a test light on post and connecter if the light comes on there is a draw pull fuses untill the light goes ou then that is the problem area

    Definitely check the cable connections at the battery. If the battery is only 1 month old, odds are it should have been charged sufficiently from the drive home to restart the vehicle, although allowing the vehicles battery to be charged by the alternator is never a good idea (this will overwork the alternator and possibly cause overheating resulting in reduced operational life of the alternator).
    Initially there may have been a load left on or parasitic drain somewhere else causing the initial no start, but again, after getting the vehicle up and running, the alternator should have been in good enough shape to operate the vehicles electronics normally, not under reduced power like you are describing.
    Please keep us informed as to your findings.

    Cable connections were a bit loose at the battery, got that fixed and also had to replace the alternator again after getting it tested. Car worked for about a day, and now won't start again. Has power, and is turning over, but the engine won't catch.
