Service Life of Tire Pressure Monitoring System?
2 Answers
The service life of tire pressure monitoring systems can be categorized as follows: 1. Built-in sensor battery: For example, VICTON's lasts 7-8 years. 2. External sensor battery: VICTON's can be used for about 3 years. 3. Display battery: VICTON's USB rechargeable version lasts about 45 days per full charge. If it's a solar battery, it can last permanently. Additional information: 1. Principle: The service life of tire pressure monitoring sensor batteries mainly depends on the designed power consumption; lower power consumption results in longer usage time. 2. SAFETYTRON: SAFETYTRON's built-in tire pressure monitoring system sensor battery can last about 5 years, with the lowest power consumption in the industry. 3. Steel-mate TPMS 700: The Steel-mate TPMS 700 tire pressure monitor adopts Infineon's globally mature OE-standard solution for its battery and features built-in displacement sensing with global patent technology.
I have an old car, and the original tire pressure monitoring sensor lasted about 9 years before giving me trouble. It's a direct type, and the internal battery probably can't hold up anymore—now the warning light keeps coming on, which is really annoying. Unstable tire pressure during long trips can be dangerous, so I went to the repair shop to check it out. The boss said the sensor's lifespan mainly depends on usage habits—if you often drive on rough roads or highways, wear and tear accelerates; for regular city driving, it can last 5 to 10 years. For routine maintenance, I suggest having the technician check the sensor's sealing ring and battery condition every time you change tires—this can extend its lifespan by several years. Remember, even if the tire pressure monitor fails, don’t take it lightly—keep a handheld pressure gauge as a backup. Safety first!
