客户前两天问我的朋友在车上QQ打不着火，找人拖车，只是立即拖动另一个名字，结果不能击败了车，并进入细胞，这怎么回事？其实，这个问题可能已经遇到了很多车主需要更换电池电量低。但是，很多人在车上，这些症状是不太好，所以害怕。其实几乎耗尽电池电量，系统会提示前车通过各种标牌，车主通常可以观察到一个单一的，在夜间行驶时，挂入空挡，自动停车或红灯车，灯光将变暗，显着，这表明，电池的寿命即将结束。由于发动机在空挡怠速，不足以提供夜间灯光的电力，则基本上由电池供电，当电池达到了生命的尽头，是不是足以提供足够的照明用电，所以灯光会变暗。
第二，启动汽车时，它显然是发动机动力不足时的前点火的速度。
三，找一个语音音喇叭
第四，打开大灯，像明亮的白光，表明电池是正常的，如果暗红色的光，这意味着动力不足。起动发动机，如果按正常的速度，虽然灯光较暗，但仍然有足够的亮度，良好的电池，充电不够的，如果发动机显得无力，和光很暗，过度放电的电池，尽快充电，如获得通过机器，暗光，并立即关闭机器，那么电池的放电超出限制或板已严重硫化。如果汽车是完全没有电，没有灯显得更亮和喇叭无声的情况，甚至无法打开收音机。  

Two days before the customer asks my friend in the car QQ beat the fire, and looking for someone to trailer, just drag another name immediately, the results can not beat the car and enters the cell, and how this happened? In fact, this problem may have met a lot of car owners who need to replace the battery is low. But many people in the car these symptoms are not too good, so frightened. Actually almost run out of battery power before the car will be prompted through a variety of signs, vehicle owners can usually observe a single, driving at night, when the hanging car into neutral, automatic parking or red light, the lights will dim significantly, this indicates that the lifetime battery is about to end. Because the engine is idling in neutral gear, enough to provide electricity at night lights, then basically powered by a battery, when the battery reaches the end of life, is not sufficient to provide enough electricity for lighting, so lights will be dimmed.
Second, start the car when it was clearly underpowered engine when the speed of the previous ignition.
Three, find a voice tone horn
Fourth, open the headlights, like a bright white light, indicating that the battery is normal, if the dark red light, it means lack of power. Start the engine if the normal speed, although the lighting is darker, but still there is enough brightness, good battery, charging from enough, If the engine seems weak, and light to very dark, excessive discharge of the battery to be charged soon, such as access through the machine, the dark light, and turn off the machine immediately, then the battery discharge limits are exceeded or plate has been vulcanised seriously. If the car is completely without electricity, no lights appear brighter and horns silent situation, and even the radio can not be opened.
