What are the solutions for car battery issues?
2 Answers
Car battery issues can be addressed by: 1. Inspecting the wiring and tightening the connection terminals; 2. Checking if the battery is undercharged; 3. Using a multimeter to measure whether the battery voltage is normal; 4. Verifying if the alternator is generating electricity properly and checking for any power leakage; 5. Examining the distribution system composed of relays or fuse boxes in the engine compartment for any abnormal discharge. The functions of a car battery include: 1. Providing power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. Supplying power to the vehicle's electrical equipment when the engine is off or idling at low speed; 3. Assisting in powering electrical devices when the alternator output is insufficient; 4. Cushioning voltage spikes to protect the vehicle's electronic equipment; 5. Storing excess electricity generated by the alternator.
I've dealt with car battery issues several times. Once in winter when my car wouldn't start, I immediately used jumper cables connected to a friend's battery for emergency help—red clamp to positive terminal, black clamp to negative terminal. After starting, don't turn off the engine immediately; let the car run for dozens of minutes to recharge. If the battery is severely aged, such as being used for over 3 years or with voltage below 12V, it's time to replace it with a new one. Regular maintenance is crucial—periodically check the electrolyte level; add distilled water if it's too low but don't overfill. Also, clean the battery terminals to prevent corrosion and oxidation; you can use baking soda solution and a small brush to scrub them clean. For prevention, avoid listening to music or leaving lights on for too long after turning off the engine, and parking in a warmer garage during winter can extend the battery's lifespan. Unresolved battery issues can easily damage the alternator, which would be even more expensive to fix.
