The best way to find out what exactly is wrong with your car if it doesn’t start is to have a professional mechanic diagnose it.

Slow engine crank, Low battery fluid level, swelling bloating battery case, battery leak, and old age are possible reasons why your car battery is dead.
Put on a disposable glove, clean the battery poles with a clean towel. Place a small amount of vinegar in a container such as a cup. Pour the vinegar over the battery pole/poles that are corroded. Wait for about five minutes then wipe the corroded area with the towel until the poles are cleaned and dried.
Corrosion on the battery terminal is due to hydrogen gas being released from the acid in the battery. It mixes with other things in the atmosphere under the hood and produces the corrosion you see on the terminals.
