Sylphy's original factory battery is a Varta brand battery. The following is a related content introduction: 1. Original factory battery: The original factory battery of the Sylphy is a Varta brand battery with capacity parameters of 12V45AH. Once the battery is dead, the vehicle will not start, especially in cold regions. It is important to avoid complete discharge of the battery to prevent the electrolyte from freezing. 2. Service life: The normal service life of a car battery ranges from 1 to 8 years, which largely depends on the condition of the vehicle. If the vehicle's alternator charges normally and there is no leakage or grounding of electrical equipment, the battery can generally last for more than 3 years. 3. Car battery maintenance: The battery should be regularly maintained. If poor power supply is detected, avoid using the vehicle's power sources such as electric air pumps, audio systems, warning lights, and power windows before starting the car.

My Dongfeng Nissan Sylphy was purchased 3 years ago, and it came with a Varta battery from the factory, which has been quite durable so far. During the last maintenance, the mechanic mentioned that this model usually comes with Varta, Hitachi, or Yuasa batteries from the factory, depending on the production batch. The battery model is typically around 60Ah, such as 55B24L or 65D23L, located at the front right of the engine compartment. Recently, it's been struggling to start in the cold weather, so I'm planning to switch to Varta's Silver series, which is said to have better cold-cranking performance. I recommend paying attention to whether the electrodes are oxidized when replacing the battery. Last month, after cleaning the rust from the terminals, the charging efficiency improved significantly, which can help extend the battery's lifespan.

The selection of batteries for the Sylphy is quite particular. A friend who works at an auto repair shop once discussed this topic with me. The original equipment mostly uses Hitachi or Varta, but later when I went to the 4S store to replace the battery, I found that at the same price, I could also choose domestic big brands like Camel. The key is to look at the cold cranking amps (CCA) value. My 2016 model requires a CCA value above 350A; anything below that can easily cause the car to stall in winter. Last year, when I replaced the battery, I was torn about whether to pair it with an AGM battery for the start-stop function, but in the end, a regular battery worked just fine. I remember one time I forgot to turn off the reading light, which drained the battery. After jump-starting, it still lasted for over half a year. Now, I use a charger to top it up for half an hour every month, and the battery condition is maintained quite well.

My experience changing the battery for the Sylphy was quite memorable. The original Hitachi battery lasted exactly four years before I realized it needed replacement when the dashboard lights flickered during startup. The auto parts store owner recommended a Varta Blue Dynamic battery, with the packaging clearly marked as the compatible 55B24L model for the Sylphy. During the DIY replacement, I noticed green crystalline deposits on the terminal posts, which I cleaned off with boiling water before installing the new battery. When testing the car, I specifically checked the voltage - 14.2V at idle confirmed the alternator was functioning properly. I've since developed a habit: regularly inspecting the battery box drainage holes during rainy seasons, and promptly clearing accumulated water after heavy rains to prevent short circuits.
