What is the lifespan of the built-in tire pressure battery?
2 Answers
The lifespan of the built-in tire pressure battery is generally around 3-5 years. Here is more information about built-in tire pressure: 1. Battery brand: The built-in tire pressure usually uses Japanese-made Maxell batteries. In terms of the battery itself, its manufacturing process meets automotive-grade requirements (-40°C to 125°C high temperature), with excellent battery discharge performance. The battery uses a 2032 300mAh battery capacity, offering extremely good stability. 2. Function of built-in tire pressure: The tire pressure monitoring system is a type of active safety equipment. It can promptly alert the driver when there are signs of danger in the tires, prompting them to take appropriate measures, thereby avoiding serious accidents.
I've been driving for over ten years, and the battery life of built-in tire pressure monitoring systems is generally around 5 to 10 years, depending on the vehicle model and usage habits. In my old car, the sensor battery died after 7 years, and the tire pressure light started flashing non-stop, so I had to rush to the repair shop to replace the sensor. The battery is a built-in lithium-ion type, and once it's depleted, the entire unit must be replaced—you can't just swap out the battery. The cost per wheel is about 50-200 RMB, which isn’t expensive, but don’t delay. When driving, pay attention to environmental factors, such as frequent parking outdoors in high temperatures, which can accelerate battery wear, or driving often on bumpy roads with lots of vibrations, which can also shorten its lifespan. Safety-wise, without TPMS, you’re more likely to miss slow leaks and risk accidents, so it’s recommended to manually check tire pressure every six months—don’t wait for the warning light. Developing good habits can help extend the system’s lifespan by a few more years.
