What does it mean when the vehicle displays battery positive and negative poles?

When the vehicle displays battery positive and negative poles, it means the generator is not working. Here are relevant explanations about this situation: 1. Reasons: The battery power will be quickly depleted without replenishment. Then the fuel pump, injector, spark plug, combustion control module, and various sensors will all stop working, leaving the vehicle stranded on the road. It's necessary to drive to the nearest repair shop as soon as possible for generator repair or replacement. 2. Precautions: Regularly check the tightness of all fasteners related to the generator and promptly tighten all screws. When using an integrated circuit regulator, immediately turn off the ignition switch if the engine is not running. If the generator fails to generate electricity, the issue should be resolved promptly to avoid more serious malfunctions.
If my car shows a positive and negative battery terminal issue, I estimate the most common cause is the battery itself aging and losing sufficient charge. Possible reasons also include the alternator not working and failing to charge the battery, or corroded/loosened wire connections. I remember one time when my car kept acting up while driving—don’t panic right away. Get out, pop the hood, and check if the battery terminal bolts are tightened properly and whether there are signs of corrosion. If a charging system fault goes unaddressed, the car might suddenly stall in the middle of the road, which is very dangerous. I recommend quickly testing the voltage with a multimeter—if it’s below 12.5 volts, head to a repair shop for a new battery and alternator inspection. During routine maintenance, pay attention to the battery’s lifespan; generally, it lasts about 4 years before needing replacement, preventing minor issues from turning into major hassles.
When I first started driving, I encountered the battery warning light on the dashboard. It was mostly due to a faulty alternator preventing the battery from charging, which is particularly common during cold starts in winter. It's best not to rush into a long-distance drive. Instead, find a safe place to pull over and check if any fuses have blown. Also, inspect the battery casing for any signs of swelling or cracks. Don't forget that accumulated dust on the terminals can cause poor contact—clean them with a brush and try again. I recommend keeping a car emergency power supply in the vehicle to avoid being stranded at critical moments. Regular checks can also reduce such unexpected incidents and enhance your sense of security.
