- A faulty alternator: The alternator is responsible for charging the battery while the car is running. If the alternator is not working properly, it will not be able to provide enough power to the battery, which will eventually cause it to die.
- A bad battery: If the battery itself is damaged, it will not be able to hold a charge. This can be caused by a number of factors, such as age, extreme temperatures, or overcharging.
- A loose or corroded connection: The cables that connect the battery to the alternator and the starter motor can become loose or corroded over time. This can prevent the battery from getting the power it needs to charge properly.
