Engine is Slow to Start
If you notice that your car takes longer than normal to fire up, the culprit could be a bad battery. Normally, the battery provides the initial energy to get the engine running.
If it takes a long time, or your engine sputters a lot when turning the ignition key, the battery is likely to blame.

Batteries produce a lot of energy and they need a way to manage that heat. If the battery has too much current, it can cause the gas inside the cells to heat and expand.
This results in battery swelling. Swollen batteries may also be hot to the touch.
