    1-Your engine cranks, but it doesn't start.

    2- Your engine doesn't crank or start, and the lights don't come on!

    3-One day it starts fine, then the next day it won't start at all.

    4-Cold cranking is hard work.

    5-You've jumped it a lot already.

    It fails to charge at all.

    It fails to hold a charge for a reasonable period of time.

    It provides too little use time between charges to be practical.

    It gets hot while charging and/or while being used.

    It leaks chemicals.

    Difficulty starting the car at times, sounds of engine straining to turn over, etc. Other than that, only someone with a battery test kit can tell you for certain.
