How many days can a new car battery sit unused before it dies?

[BarrettRose]

A new car battery will die if left unused for half a year. Methods to prevent battery drain: When not driving for extended periods, it is recommended to recharge the battery periodically. For batteries over one year old, recharge every two weeks. The frequency depends on whether it's a new or old battery - in winter, an old battery may die after just one week of inactivity. Car battery maintenance tips: Avoid parking the car in open parking areas for long periods. If long-term parking is necessary, remove and take the battery with you to prevent freezing damage. Car engines are harder to start in winter - each starting attempt shouldn't exceed 5 seconds, with at least 15 seconds between attempts. If the car fails to start after multiple attempts, check other systems like electrical circuits, ignition coils, or fuel systems. Avoid continuous starting attempts as this may cause battery damage from excessive discharge.
