Causes of a Dead Car Battery
A dead car battery can be caused by a variety of factors, including:

|---|---|
| Old Age | A car battery typically lasts for around 5-7 years, depending on the type and quality of the battery. As the battery ages, its ability to hold a charge decreases, making it more prone to dying. |
| Corrosion | Corrosion on the terminals or cables can prevent the battery from functioning properly, causing it to die. |
| Overcharging | If the battery is overcharged, it can cause the electrolyte to boil off, leading to a dead battery. |
| Undercharging | If the battery is undercharged, it can cause the plates to sulfate, leading to a dead battery. |
| Drain on the Battery | If there is a drain on the battery, such as a faulty alternator or a parasitic drain, it can cause the battery to die. |
