Long distance cross-border sports cars, warning signals that are easily overlooked before the battery runs out of power

Long distance cross-border routes have complex road conditions and few maintenance stations along the way. Battery failure and breakdown can delay customs clearance and transportation efficiency. Many warning signs of battery failure are not obvious and can easily be ignored by drivers as minor issues. Firstly, the lights and instrument panel flicker slightly during idle, and there is no abnormality in the continuous power supply of the generator during normal driving. When parking and idling, turning on the parking lights or warm air, the headlights dim and the instrument pointer shakes slightly, which is a signal of decreased battery storage capacity and voltage stabilization ability. Many drivers mistakenly believe that it is just slow charging of the generator and fail to check in a timely manner. Secondly, the power consumption during parking becomes faster when the car loses power. After running for a long day and turning off the engine, only a short section of the driver's cabin reading light or radio is turned on. The next day, the power consumption is weaker when starting, which is significantly different from the power consumption during the new car era. It is not simply due to the installation of electrical appliances that consume electricity, but rather due to the increased internal resistance of the battery, which cannot store electricity. There are also subtle changes during startup, which may not necessarily result in a complete failure to start, but rather a slower running rhythm and muffled sound of the starter motor. Occasionally, there is a clicking sound before the ignition is successful. Many drivers attribute this to low temperatures and ignore the issue of battery aging. In addition, the inexplicable reset of car electrical appliances is also an implicit signal. After turning off the engine, frequent resets of the radio, driving recorder, and instrument settings indicate a momentary drop in voltage, making it difficult for the battery to maintain stable low-voltage power supply. The battery pile head is also a place that is prone to leakage. The terminals turn white and have powder corrosion, which increases the circuit resistance and causes losses while charging. When there is electricity, the voltage drops directly from the load. Also pay attention to the abnormality of the charging indicator light. The indicator light is not always on to give an alarm, but occasionally flashes and most of the time goes out. This intermittent fault is more likely to be missed, often due to unstable generator output combined with battery performance degradation. Before cross-border driving, a multimeter can be used to measure the static voltage. If the static voltage of a 24V vehicle is too low, it is necessary to investigate in advance and check whether the pile head is fastened and whether there is any hidden leakage in the circuit. Do not drive long distances when encountering the above warnings. Prioritize cleaning the wiring terminals and testing the charging output. If the battery performance deteriorates severely, replace it in a timely manner. The cost of emergency power on cross-border roads is high and the waiting period is long. Identifying these signals in advance can greatly reduce the risk of stalling and getting trapped halfway.
