How Long After Production Can a Car Battery No Longer Be Used?
1 Answers
Car batteries cannot be used if they have been in storage for more than three months after production. Typically, if a car is left unused for half a month, the battery may still have some charge, but the voltage will have dropped, making it difficult to start the vehicle. If the car remains parked for over three months, the battery will almost completely discharge. Below are some tips for car battery maintenance: 1. Turn off all lights before shutting down the engine: Some older car models do not support automatic power-off after the engine is turned off, so it is necessary to manually turn off the headlights and interior reading lights before shutting down the engine. If you need to find something inside the car or require lighting, you can use a mobile phone or flashlight to avoid forgetting to turn off the reading light, which could lead to battery drain. 2. Avoid leaving the car parked for extended periods: Batteries installed in cars will self-discharge over time if left unused. Many car owners find it difficult to start their cars or discover that the battery is completely dead after returning from a business trip or vacation. Therefore, it is advisable to drive the car at least once a week, with each trip lasting at least 20 minutes, to allow the battery to recharge while the car is in motion.
