It is due to a depleted battery. Below is the relevant introduction: Battery: A battery is a type of cell, also known as an accumulator, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Misconceptions: When the liquid level is low, people often replenish it with electrolyte or drinking purified water instead of the required distilled water. Adding electrolyte containing sulfuric acid will increase the concentration of the electrolyte inside the battery, leading to phenomena such as boiling and acid mist, severely affecting the battery's lifespan. Using drinking purified water instead of distilled water is also problematic, as purified water contains various trace elements that can adversely affect the battery.

Keep the battery surface dry and use soda water or distilled water to remove any corrosion. Ensure the terminals are clean and securely connected. If the car is unused for more than 30 days, disconnect the negative terminal to prevent battery drain.

Can 12123 Display Traffic Violations Immediately?

12123 cannot display traffic violations immediately. 12123 is just a platform and does not show violations right after they occur. Traffic violations are determined through electronic monitoring, and the captured behavior needs manual review. The records are usually uploaded within approximately 72 hours, and they can be checked on the 12123 platform within a week at most. There are two ways to handle violations: online processing and processing at the vehicle management office. Online processing has certain limitations, such as being applicable only to violations with fines not exceeding 200 yuan, violations where the penalty points do not reach 12 after deduction, and non-on-site enforcement violations. Processing at the vehicle management office is a more reliable method. Nowadays, many vehicle management offices have self-service terminals for handling violations, with staff available to guide users. Handling minor violations can usually be completed in just two to three minutes.
