What is the usage method of car battery charging clamps?
2 Answers
The usage method of car battery charging clamps is: connect the positive clamp to the positive terminal of the battery, and the negative clamp to the negative terminal of the battery. The functions of the battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. To supply power to the car's electrical equipment when the engine is stopped or at low idle speed; 3. To assist in supplying power to electrical equipment when the generator's output is insufficient; 4. To mitigate impact voltage in the electrical system and protect the electronic equipment in the car; 5. To store excess electricity generated by the alternator. The maintenance methods for the battery are: 1. Start the car regularly to charge the battery; 2. Add distilled water or special replenishing fluid when the electrolyte is insufficient; 3. Frequently check whether the small holes on the battery cover are ventilated during daily driving; 4. Check whether the positive and negative terminals of the battery are oxidized; 5. Check whether any part of the circuit is aged or short-circuited; 6. Turn off electrical equipment when leaving the car.
I usually drive a family car and have encountered a dead battery situation. Using jumper cables is quite simple but requires caution. First, park the car in a well-ventilated area, ensuring the engine is off and the key is removed. Securely attach the red clamp to the battery's positive terminal, marked with a + sign—never get this wrong. The black clamp should be attached to any clean, unpainted metal part of the car frame, such as a bolt on the engine block, to avoid sparks from directly connecting to the negative terminal—I once reversed them and blew a fuse. Once clamped tightly, turn on the charger power and typically charge for a few hours while monitoring the indicator. After charging, first turn off the charger, then remove the black clamp, and finally the red clamp. For safety, never forget to wear gloves and goggles to protect against acid splashes. Battery maintenance, like regularly cleaning terminal corrosion, is also crucial. This method works well for emergencies—just remember to use cables that aren’t too thin to ensure smooth current flow. I’ve managed to extend my battery’s lifespan for years this way.
