What are the precautions after replacing a car battery?

When replacing the battery, visually inspect the casing for any cracks, corrosion, or signs of burning; use a voltmeter to measure the voltage between the casing and ground, ensuring it does not exceed 20V, as higher voltage poses an electric shock risk; after installing the new battery, perform a battery test run using Mercedes-Benz specialized computer. Below are the precautions for car battery maintenance: Frequent Driving: Avoid leaving the vehicle unused for extended periods. Drive regularly to keep the battery fully charged. Pay Attention to Equipment Usage: Turn off lights before shutting off the engine and minimize the use of charging devices in the car to prevent battery drain. Regular Inspections: Have the battery's charging capacity checked at a 4S shop every six months. Replace the battery if its performance declines. Regular Cleaning: Wipe the battery periodically to prevent the formation of corrosive acid powder.
Replacing the battery is something I take very seriously. First, after installation, check if the positive and negative terminals are securely connected without being twisted, otherwise, bumps while driving might loosen them and cause a power cut. Next, start the engine for a test run to see if the dashboard lights come on and if the starting sound is smooth. If you notice difficulty starting or flickering lights, it means further troubleshooting is needed. Tightening the mounting screws is crucial—skipping this step could lead to short circuits or even fires due to vibrations. Don’t just toss the old battery in the garage; lead-acid batteries are toxic, so take them to a recycling center or dealership for eco-friendly disposal. Regular maintenance is key—clean the terminals periodically to prevent corrosion and dust buildup, ensuring the new battery lasts 3-5 years without issues, saving both money and hassle. Also, don’t forget to check the voltage—it should be around 12.6 volts normally, and after starting, verify if the alternator charges at around 14 volts. These details help prevent major failures. In short, following these simple steps ensures safer and more reliable driving.
