Why does the car display low battery voltage?
2 Answers
The reasons for the car displaying low battery voltage are: 1. Uneven distribution of electrolyte on the lithium-ion film or the presence of line faults; 2. Rapid consumption and reduction of the number of ions in the electrolyte. The car battery, also known as a storage battery, works by converting chemical energy into electrical energy. Its maintenance methods include: 1. Avoid parking the car in an open parking lot for extended periods; if long-term parking is necessary, remove the battery and take it with you; 2. Avoid repeatedly starting the vehicle without intervals; 3. Start the car periodically to keep the battery sufficiently charged; 4. Regularly check the battery's accessories and connecting circuits; 5. Avoid using car electronics after the engine is turned off.
I recently encountered this issue when my car's dashboard kept showing a low voltage warning light, which was quite alarming. It could be due to the battery aging after prolonged use, or the alternator not charging properly, which is related to leaving the car parked for too long without driving, causing the battery to naturally discharge over time. If you frequently leave the audio, lights, or other electrical devices on after turning off the engine, it can further drain the battery and reduce voltage. If the voltage is too low, the car might stall when starting, especially in cold winter weather, making it more likely to face such an awkward situation. Last time, I took it to a repair shop for a check, and they said the battery's performance had degraded and needed replacement. Fortunately, it only cost a few hundred bucks to fix. Since then, I make sure to turn off all electrical devices when parking to avoid trouble. I suggest you get it checked early, unlike me who waited until the problem occurred on the road to panic—it really messes up your daily travel plans.
