The most common problems with car batteries are corrosion, sulfation, and short circuiting. Corrosion can occur when the battery is exposed to moisture over a long period of time, which causes the plates in the battery to corrode and eventually lead to failure. Sulfation occurs when sulfuric acid builds up on the plates inside the battery, causing them to lose capacity. Short circuiting happens when an electrical current passes through the wrong path in the battery and causes it to overheat, leading to damage or even fire.
