Winter car battery maintenance

Before connecting the wire to the powered vehicle, be sure to turn off the engine; 2. After connecting the wire to the powered vehicle, be careful not to make the positive and negative poles of the wire contact, short circuit is very dangerous. 3. When removing the wiring, remove the negative electrode first, and then remove the positive electrode. Under normal circumstances, only a car whose battery is losing electricity can be ignited smoothly after going through the above steps. If the car with no electricity still cannot start, then don't panic. This is because the battery of the car with no electricity has too little residual electricity, and the electricity of the powered vehicle is not enough to start. This is also a normal phenomenon. At this time, we can charge the dead car for a while (powered car can accelerate the charging speed by hitting the accelerator). If your battery is normal, it should start smoothly in 10-15 minutes.　　 If there are no tools around us, the easiest way is to use a cart to help the ignition. However, the cart requires several conditions. First, it is necessary to ensure that there is some remaining battery in the battery. If the battery is completely consumed, the cart will not help. Second, the cart method is only for manual transmission models and automatic transmission. The vehicle cannot be started by a cart, nor can it be towed with a tow rope. It can only be towed by a wire or a flatbed rescue vehicle to a 4S shop for repair.　　 The principle of 'pushing' the car is to use human power to push the car, and this kinetic energy reacts on the piston of the cylinder to forcefully compress the gas in the cylinder and burn it. Before pushing the cart, we'd better find a driver who is skilled in the operation of clutches and gears to be responsible for the ignition, and find a few people behind to push the cart. Before pushing the car, the driver needs to turn the key to the energized position (ON), and then put the gear, when the car is pushed up a little speed, immediately raise the clutch, if the engine starts and can idling normally, it is OK . After the ignition is successful, do not turn off the flame and keep the idling speed for a period of time to charge the battery; or you can simply drive on the road for a lap, so that the charging effect will be better.　　 There is a detail to pay attention to, that is, the driver in front of the vehicle must enter the second or higher gear after the vehicle moves forward, otherwise it is likely to 'frustrate the car' because the transmission ratio of the first gear is generally very large. Of course, the car can be started smoothly when the cart is in 1st gear, but in this way, the car will suddenly slow down and then start instantly, which can easily cause the person behind the cart to hit the rear of the car and cause injury. It would be much more convenient if there were tow ropes and other rescue vehicles.
