Why does the car battery drain overnight?
1 Answers
If the car battery drains overnight, it indicates a deep discharge condition in the vehicle's battery. Solution: You need to take the car to a repair shop for servicing. If the normal voltage cannot be restored, the battery needs to be replaced. Car battery replacement: When replacing the car battery, you can choose batteries of the same voltage from different brands or opt for an original equipment manufacturer (OEM) battery. Currently, most car batteries use maintenance-free batteries. Battery types: Car batteries are divided into maintenance-free batteries and traditional batteries. Maintenance-free batteries have structural advantages, and their service life is twice that of traditional batteries, reaching up to 6 years.
