How long can a car sit without the battery dying?

[LeViolet]

If your car's battery is relatively old, it may die after just two weeks of inactivity. If the battery is brand new, it could last about a month without use before losing charge. If you don't plan to use the car for an extended period, it's recommended to disconnect the negative terminal of the battery to prevent it from discharging. Battery function: The battery is a crucial component in a car. Without it, the vehicle cannot operate normally. When the engine is off, the battery powers all electronic devices in the car and is also responsible for starting the engine. During engine startup, components like the starter motor, fuel supply system, and ignition system all require electricity. If the battery is dead, the engine won't start properly. After starting, the engine drives the alternator, which then powers the car's electronic devices and recharges the battery. The battery is a wearable part that requires regular replacement, as its performance gradually declines with each charge-discharge cycle.
