Precautions for replacing a car battery: 1. Whether removing or installing, be careful not to touch metal when twisting the positive battery terminal; 2. When purchasing a battery, ensure it matches the original battery model of your vehicle for proper usage; 3. During replacement, maintain power connection to avoid resetting some electronic devices in the car; 4. For a power-connected replacement, first connect the new battery to the vehicle's power source, then remove the old battery before installing the new one; 5. After installing a new battery, drive for about half an hour to allow the battery to charge and ensure sufficient power; 6. After installation, test all electronic devices in the car, such as power windows and audio equipment, to ensure they function normally.
Safety first when changing the battery—that was my top priority while helping a friend. Start by wearing goggles and gloves to protect your eyes and skin from battery acid splashes. Then, use a wrench to disconnect the negative terminal first, followed by the positive, to prevent short circuits that could cause sparks or damage the car's electronics. Remove the old battery carefully, avoiding tilting to prevent leaks. Before installing the new battery, check if the specifications match, such as CCA (Cold Cranking Amps) and dimensions, ensuring compatibility with the vehicle. Clean the terminals and apply a bit of anti-corrosion grease. Finally, connect the positive terminal first, then the negative, tightening the bolts firmly but not excessively to avoid damaging the terminals. Don’t discard the old battery carelessly—take it to a recycling center for environmental safety. The whole process takes about ten minutes, but attention to detail is crucial.
