1 Answers
Precautions for replacing a car battery include: 1. Confirm the battery installation location. In most models, it is installed in the engine compartment or luggage compartment, while some models may have it installed in the cabin; 2. Remove external protective devices such as the battery cover and measure the voltage between the two poles with a multimeter; 3. If the vehicle is equipped with an anti-theft system (including audio anti-theft), you can first connect an external power source or parallel a fully charged battery. Note to connect the positive terminal first and then the negative terminal. The positive terminal of the external power source can be directly connected to the positive terminal post, but the negative terminal should not be directly connected to the negative terminal post. Instead, it should be connected to the vehicle body ground; 4. Turn off the ignition switch of the faulty vehicle, disconnect the negative connection first, then the positive connection; 5. Remove the battery's fixing device and take out the battery. If the vehicle is connected to an external power source, be careful not to let the positive terminal contact the vehicle body. Use cotton cloth or other materials for isolation; 6. If the old battery has leakage or corrosion, clean the connections and other related parts.
