What is the battery life of an external tire pressure monitoring system?

[EllaRose]

Different brands of tire pressure monitoring devices use different types of batteries, resulting in varying lifespans. When the battery of a tire pressure monitoring device is depleted, it does not necessarily mean the device is scrapped—it can often be replaced to extend its service life. The tire pressure monitoring system alerts the driver when the tire pressure is too high, too low, or when the temperature is elevated, ensuring driving safety. The steps to replace the battery in a tire pressure monitoring system are as follows: 1. Remove the tire, take out the tire pressure sensor, and replace it with a spare tire. 2. Use tools to remove the silicone seal of the tire pressure sensor. 3. Pry out the circuit board and remove the old battery. 4. Insert one end into the disassembly tool. 5. Close the disassembly tool and twist it back and forth forcefully. 6. Once loosened, the battery can be removed. 7. For the new battery, solder it with nickel strips and secure it to the circuit board using a soldering iron, ensuring no short circuits and verifying voltage. 8. Reassemble the sensor following the original method and tighten it using the disassembly tool.
