The original battery of Nissan Sylphy cannot be left unused for a long time. Here is the relevant information: 1. The original battery of Nissan Sylphy cannot be left unused for a long time, as the battery may become too weak to start the car after prolonged inactivity. It is necessary to check it in time and replace it with a new one if needed. 2. To prevent the car battery from discharging due to long-term parking, the best practice is to start the car regularly and let the car's built-in generator charge the battery. If the battery is in good condition, starting the car once every half month and running it at about 2,000 rpm for about half an hour can basically replenish the self-discharge of the battery. If the battery's technical condition is not good, it is best to start the car once a week. 3. Modern cars do not recommend disconnecting the battery connection line. On one hand, after disconnecting the line, the car's anti-theft system will stop working, posing a risk of theft or damage to the car. On the other hand, after the battery is disconnected, many settings on the car will be lost and need to be reset when the car is used again. Some cars even require a special computer to reset the engine control unit system before they can be started after the battery is disconnected, which is not worth the effort.
I've been driving a Nissan Sylphy for two years, and the original car battery is really not durable. Last winter, I went on a trip and left the car at home for almost two months without moving it. When I came back, it wouldn't start no matter what, and the dashboard was completely dark. I had to call for roadside assistance, which cost me 200 yuan to get it fixed. I chatted with the mechanic, and he said that batteries naturally discharge over time. Nissan's AGM battery is considered average, but if left unused for too long, the charge will slowly drain. If it drops below 10 volts, the battery is likely to fail. The best practice is to start the car every two weeks and drive a few kilometers, or buy a smart battery maintainer to keep it charged. This way, the battery can last several more years. Also, regularly check the battery terminals to ensure they're not loose and that there's no leakage or corrosion, to avoid premature failure and unnecessary expenses on a replacement.
