Can a New Battery That Has Been Idle for 10 Years Still Be Used?

[LaDawson]

New batteries that have been stored for 4 years generally cannot be used anymore. Below is relevant information about car batteries: Service Life of Car Batteries: Generally, the design lifespan of a car battery is 27 months. For household vehicles, they can last longer, with new car batteries typically lasting 3 to 4 years. Battery Maintenance Methods: Some older car models do not support the automatic power-off function after the engine is turned off, so it is necessary to manually turn off the car lights and interior reading lights before turning off the engine. If you need to find something in the car or require lighting, you can use a mobile phone or flashlight for illumination to avoid forgetting to turn off the reading lights, which could lead to battery power loss.
