How Many Years Can a Tire Pressure Monitoring System Last?
2 Answers
Tire pressure monitoring system (TPMS) battery life depends on the type of battery used. TPMS automatically monitors tire pressure in real-time while driving, alerting the driver to leaks or low pressure to ensure driving safety. Below are the lifespans for different battery types: 1. Built-in sensor batteries typically last 7-8 years. 2. External sensor batteries generally last about 3 years. 3. Display unit batteries last approximately 45 days per charge, while solar-powered displays can operate indefinitely.
I've been driving for several years and know quite a bit about tire pressure monitoring systems. They generally last 5 to 10 years, but it depends on the car brand and usage habits. For example, my first car was an ordinary family sedan, and the sensor failed after just over 4 years due to a drained battery. If the sensor is exposed to harsh conditions, like frequently driving on dirt roads or in hot weather, its lifespan may shorten to around 3 years. Don't ignore the warning light if it shows an abnormality—it might be time for a replacement. I recommend having a mechanic check the battery condition during your 1-2 year maintenance service. Replacing it only costs a few dozen bucks, much easier than doing it yourself. Always pay attention to tire pressure changes—safe driving is the top priority. Don’t wait until a blowout to regret it; this system can help you avoid accidents on long trips.
