Why is the battery green light not on?

The reasons why the battery green light is not on are as follows: Failure of the small battery in the battery pack: For this type of problem, the general solution is to replace the entire battery pack, which can resolve the issue of the charging light not switching off. It is important to note here that one should not deliberately attempt to replace just one small battery, as mismatched models may lead to more new problems. Battery dehydration failure: This situation is relatively common. Generally, if an electric vehicle battery has been used for more than three years, many will experience dehydration failure. Its typical manifestation is severe heating of the battery during charging, and the charging light not switching off. For such problems, you can go to an electric vehicle repair shop and have the technician inspect it. If the dehydration is not very severe, you can add an appropriate amount of water. However, if the dehydration is severe, then the only option is to replace the battery with a new one.
The issue of the battery's green light not illuminating is something I've noticed many car owners inquire about. Typically, this green light serves as an indicator that the battery is charging or in good condition. If it doesn't light up, the most common reasons include: first, the battery itself may be faulty, such as aging or internal issues, leading to insufficient voltage; second, there could be a problem with the charging system, where the alternator isn't charging the battery, possibly due to a loose alternator belt or a faulty voltage regulator; third, the indicator bulb might be burnt out, or there could be a loose connection in the wiring—check the battery terminals and fuses for corrosion or breaks. I recommend a simple test: use a multimeter to measure the battery voltage, which should normally be above 12.5 volts; if it's below 12 volts, the battery is likely on its last legs. To prevent many issues, avoid leaving the car idle for extended periods, regularly inspect the battery's exterior, and clean any accumulated dust on the terminals. If you need to address the problem, it's best to visit a professional repair shop rather than attempting a DIY fix to avoid causing additional problems.
I often drive to and from work and have encountered situations where the battery light doesn't illuminate quite a few times. It usually alerts us that the battery might be dead or there's a charging system malfunction. Simple steps: First, check if other dashboard lights are still on? If other lights are also abnormal, it might be a blown fuse; if only the battery light isn't working, the indicator itself might be faulty. Roll up your sleeves, pop the hood to inspect if the battery terminals are securely connected and free from corrosion. A quick clean might just do the trick. If your battery has been in use for three to four years or more, it's time to consider replacing it to avoid being stranded with a dead battery someday. Last time I faced the battery light issue, my car wouldn't start, and I had to call a tow truck. During regular maintenance, ask your mechanic to check the battery's health—it can save you a lot of hassle. Always keep an eye on this signal while driving; addressing problems early keeps the road smooth.
