Why is my new car battery dead?
There are several reasons why a new car battery might be dead. A common reason is a faulty alternator. The alternator charges the battery while driving. If it is defective, the battery will not be charged and will eventually discharge. Another reason could be a parasitic drain. A parasitic drain is a small current flow that occurs even when the engine is off, slowly draining the battery. Defective cables or electronic devices can be the cause. Sometimes the problem is also due to a silent consumer, such as an interior light that was accidentally left on.
