How Long Can a Car Sit Without Being Driven Before the Battery Dies?

Under normal circumstances, a car battery will typically die after about 1-2 months of inactivity. The exact timeframe can vary depending on factors such as the battery's quality, its remaining charge, whether the storage environment is dry or humid, and whether there are any power-draining electrical components or aging wiring in the vehicle. Car batteries have a characteristic known as self-discharge. Over time, the battery gradually loses its charge, leading to depletion and potentially irreversible damage, significantly reducing the battery's lifespan. Additionally, some electrical components in the vehicle continue to draw power even when the engine is off. Generally, if a car is left undriven for about two weeks, the battery may still have some charge, but the voltage will have dropped enough to make starting the engine difficult. If the vehicle remains unused for three months or more, the battery will likely be almost completely drained. To prevent this, it's important to periodically recharge the battery. Starting the car and letting it run for over an hour once a week or every ten days can help, but ensure the runtime is sufficiently long—otherwise, the recharge may not offset the discharge. For extended periods of inactivity, it's advisable to disconnect the battery's negative terminal. Alternatively, starting the car occasionally during downtime allows the alternator to recharge the battery, which is beneficial for its longevity.
