Can a car battery be repaired if it's broken? The method to repair it is: use a charger to supplement the voltage of the battery. Reasons for car battery damage: 1. The cigarette lighter continues to work after the engine is turned off; 2. The multimedia or air conditioning system is not turned off before the engine is turned off; 3. Using electrical appliances for a long time after the engine is turned off; 4. Frequent or prolonged ignition attempts. Methods for maintaining a car battery: 1. Avoid parking the car in an open parking lot for a long time; 2. Avoid starting the vehicle multiple times without interruption; 3. Start the car frequently to charge the battery; 4. Regularly check the accessories and connection lines on the battery; 5. Do not use electrical appliances in the car after the engine is turned off.
To be honest, whether a car battery can be repaired depends on the specific issue. If it's reached the end of its lifespan with severely aged and deformed internal plates, or if the electrolyte inside has completely dried up, it's basically done for—replacing it is the safe bet. However, if it's just mild sulfation causing charging issues, there might still be hope—using a specialized battery repair charger to slowly recharge it a few times could restore some activity. Also, if the battery terminals are covered in that white-greenish corrosion, you can grab a wrench to loosen the connectors, carefully scrape them clean with sandpaper or a small blade, apply some grease to prevent future rust, and reconnect them—that usually does the trick. I've helped neighbors fix these minor issues several times, saving them the cost of a new battery and even leaving enough for a tank of gas!
