Can a Car Battery Be Repaired If It's Broken?
2 Answers
Car batteries can be repaired. The functions of a car battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system during engine startup; 2. To provide power to the car's electrical equipment when the engine is stopped or idling at low speed; 3. To act as a voltage stabilizer for the entire vehicle's electrical system; 4. To store excess electrical energy generated by the alternator. Methods for maintaining a car battery include: 1. Cleaning the white acid corrosion powder accumulated on the battery terminals to extend its lifespan; 2. Adding distilled water to the level between the upper and lower marks; 3. Regularly checking if the battery is charging properly.
The car battery is dead, and from my years of driving experience, it's basically irreparable. The internal workings of a battery rely on chemical reactions, so once it's damaged, it's permanent—like electrode sulfation or leakage. The so-called repair methods offered by shops are just temporary fixes. I recommend replacing it with a new battery for peace of mind and safety. The replacement process is simple: first, disconnect the negative terminal, then loosen the mounting bracket and remove the old battery. Install the new one, secure it properly, and don’t forget to clean the terminals and apply some anti-corrosion grease. Regular maintenance is crucial—check the voltage periodically, and if the car is parked for a long time, remove the battery to avoid over-discharge. Choose a reliable brand like Varta, which can last three to five years. Don’t waste money on cheap repairs; they might just lead to starting issues later.
