Will the car battery die if the car is not driven for a week?

If it is an electric vehicle and the battery has not been replaced for a long time, not driving it for a week may cause the battery to die, making it impossible to start the engine. Issues to pay attention to when the car is not driven for a week: Tire pressure: First, pay attention to the tire pressure of the car. If the pressure is too low, it should be replenished. If the pressure is too low, during high-speed driving, the deflated tire will show wave-like deformation, and the friction between rubber molecules will generate heat, leading to a tire blowout, which poses a risk of the car overturning. Check the engine lubrication system: A decrease in lubricating oil will lead to poor engine lubrication, thereby damaging engine components such as gears. Parking location: The parking location of the vehicle is very important. If conditions do not permit, try to find a cool and ventilated place to park, preferably not under trees or buildings. In case of windy or rainy weather, branches, leaves, or falling objects from above may land on the car body and cause damage.
Last time I was on a business trip for exactly a week, and when I came back, I found my car wouldn't start—the battery was completely dead, which was really frustrating. I asked a mechanic, and he said a healthy battery should last about 10 days, but my car is five years old, and with the battery aging plus the anti-theft system constantly draining power, it just couldn't hold up. Winter makes it even worse, as low temperatures reduce battery performance. He advised car owners to regularly check the battery voltage with a simple tool; if it's below 12.4 volts, it's dangerous. If you don’t drive often, investing in a cheap battery maintainer (just a few dozen bucks) and plugging it in can prevent a dead battery. If you do get caught out, don’t mess around—ask a friend to help jump-start it with jumper cables or call for roadside assistance. During regular maintenance, check the battery terminals for corrosion and clean them to extend their lifespan.
