How to Start a Haval Car When the Battery is Dead?
3 Answers
If the car has been parked at home for too long, causing the battery to die, you can choose to replace it with a matching battery model. Find a deserted downhill road and have several people push the car forward simultaneously, but this method carries certain risks and should not be attempted lightly. Find another car owner to provide a jump start. When jump-starting, be sure to pay attention to the positive and negative terminals of the battery to avoid causing a short circuit.
A couple of days ago, my neighbor's Haval H6 had this issue, and I helped him jump-start it. The method is actually quite simple: first, park a car with a good battery close by without the two vehicles touching. Attach the red clamp to the positive terminal of the dead battery, and the other red clamp to the positive terminal of the rescue car. Then, attach the black clamp to the negative terminal of the rescue car, and the remaining black clamp should be attached to a metal part of the dead car's engine block, like the cylinder body. Keep the rescue car idling for about five minutes, and then try starting the dead car. I've seen people attach the clamp directly to the negative terminal of the battery and get sparks, so it's important to be careful. After a successful start, don't turn off the engine immediately; let the alternator charge the battery for a while, preferably driving for more than half an hour. If you can't find a rescue car, there are now car emergency power supplies about the size of a power bank, which are convenient to keep in the glove box for emergencies.
For a Haval car with a dead battery, I highly recommend calling for roadside assistance, but doing it yourself is also easy. Once my car broke down in an underground garage, and I managed to start it using jumper cables: make sure both cars are turned off and all electrical devices are closed. The order of connecting the cables is crucial—first connect the positive terminal of the dead battery, then the positive terminal of the rescue car; connect the negative cable first to the rescue car, and finally to the engine grounding point of the dead car. Connecting them incorrectly may damage the computer board. After connecting, let the rescue car rev to 2000 RPM, then attempt to start the dead car. Once successful, immediately remove the cables in reverse order. Remember, new Haval cars with auto start-stop require a dedicated battery, as ordinary jumper cables may harm the car. Keep a voltage tester handy; if the battery voltage is below 12 volts, it's time to recharge.
