What are the reasons why the battery of Wuling Zhiguang cannot be charged?
3 Answers
Wuling Zhiguang's battery cannot be charged due to reasons such as dried-up electrolyte in the battery, broken plates, or short-circuited plates. The most common and primary reason is plate sulfation, which obstructs the normal flow of electrons, leading to reduced battery capacity, inability to function properly, and gradual aging. If a battery is left unused for a long time or is chronically undercharged, plate sulfation can occur. For batteries that have been in use for more than 3 years, it is recommended to replace them with a new one. For batteries with shorter usage periods that have experienced mild sulfation due to short-term excessive discharge, a low-current, long-duration charging method can be used for recovery. However, the battery capacity can only be restored to about 80% of its rated capacity. There are several main reasons for the early failure of vehicle batteries: Deep discharge: When the vehicle is parked but the lighting or other electronic devices remain on, the battery continues to discharge. Prolonged discharge significantly reduces the battery's lifespan. Overcharging or engine overheating causing electrolyte evaporation: Since the electrolyte is composed of specialized sulfuric acid and distilled water in a specific ratio, engine overheating will accelerate the evaporation of distilled water, disrupting the balance between sulfuric acid and distilled water in the electrolyte and shortening the battery's lifespan. Loose alternator belt leading to insufficient charging: The vehicle's alternator supplies power to the electronic devices and charges the battery while the vehicle is in use (except during idle). If the alternator belt is too loose, it will result in insufficient charging of the battery, affecting its normal operation.
I've driven my Wuling Zhiguang for over a decade and have encountered numerous battery charging issues, often caused by alternator failures or loose belts. The alternator charges the battery, but if it malfunctions or the belt wears out and slips, the insufficient output power prevents proper charging. Also, check for oxidation or loose connections in the cables, especially at the battery terminals—rust can block current flow. The voltage regulator might also fail, causing overcharging or undercharging. I remember one winter when my car had this issue due to an aged, leaking battery. Avoid long trips in such cases to prevent breakdowns; it's best to visit a repair shop promptly to inspect the alternator system and maintain the entire electrical circuit. Regularly monitor the battery's condition and replace it periodically to avoid hassles.
As a car enthusiast, I've tinkered with the Wuling Zhiguang, and there are many reasons why the battery might not charge. First, check if the battery itself has reached the end of its lifespan—aging or internal short circuits can prevent current from entering. Is the alternator working properly? You can use a multimeter to measure the charging voltage; it should generally be between 13.8-14.8 volts to be considered acceptable. Corroded or loose wire connections are also common issues—cleaning the terminals can help. Don’t forget that blown fuses or relay failures can interrupt the circuit; locate the fuse box in the engine compartment and inspect it. During weather changes, extreme temperatures can affect the battery's chemical reactions, potentially leading to charging failure. For DIY maintenance, try simple fixes on the connection points. If that doesn’t work, have a professional technician diagnose the issue to avoid worsening the problem and compromising driving safety.
