Most car batteries utilize lead-acid, multi-cell batteries. BATTERY AGEĪnother potential cause of a dead car battery is age. That means a lot of your battery's power was used when you started your vehicle, but your alternator, which returns power to your battery, didn't have enough time to juice up your battery fully.
