    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.

    the flashlight will dim due to low battery.

    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.
