How Long Can a Car Battery Sit and Still Start the Engine?

[DelKennedy]

There is no fixed number of days for how long a car battery can sit normally, as it depends on the battery capacity and its level of degradation. Theoretically, a car can sit for up to two months without affecting the battery's normal operation. Battery Drain: The battery will still experience natural drain (approximately 1% per day). Poor Vehicle Condition: For cars in poorer condition, the battery may lose charge within about a week. However, there's no need to worry excessively—simply driving normally for one to two hours can restore the battery to its normal charge level. If the battery is already severely depleted to the point where it cannot start the engine, a jump-start will be required to reactivate it.
