How Long Does the Battery of a Tire Pressure Monitoring System Generally Last?
2 Answers
Here are the specific details about the battery of a tire pressure monitoring system: 1. Built-in sensor battery: The battery lifespan is 7-8 years. The sensors of built-in tire pressure monitors are installed inside the tires, making this form relatively more stable, and the monitored data is more accurate. The principle involves using pressure sensors installed in each tire to directly measure tire pressure, and wireless transmitters to send pressure information from inside the tire to a central receiver module, which displays the tire pressure data. 2. External sensor battery: The battery lifespan is 3-5 years. Installation is convenient and can be done by oneself. Tire pressure parameter measurement is also quite accurate, and the sensor's lifespan can be extended by replacing the built-in battery later. 3. Display battery: When fully charged, it generally lasts about 45 days.
I've driven several cars before, and generally speaking, the battery life of tire pressure monitoring sensors lasts around five to ten years, but it really depends on the specific situation. For example, the sensors in my current car lasted six years before needing replacement because I don't drive much, with minimal city commuting, so the battery drained slower. However, for cars frequently driven on highways or in areas with large temperature variations, the battery tends to degrade faster—sometimes needing replacement in just three or four years. Additionally, the type of battery matters a lot. Some sensors have built-in, non-replaceable lithium batteries, which tend to have more stable lifespans. If the sensors are externally mounted and allow DIY battery replacement, you need to be careful about water damage. The key point is, once the battery fails, the tire pressure warning light on the dashboard starts flashing erratically. I once experienced this—my tire pressure monitoring system malfunctioned, leading to a blowout on the road, nearly causing an accident. So, I recommend car owners regularly check their tire pressure systems and not skimp on repairs—safety comes first! Also, when replacing the battery, just find a reliable shop—it usually costs a few hundred bucks, which is way cheaper than dealing with car repairs later.
