How Long Does the Battery of a Tire Pressure Monitor Last?
2 Answers
The service life of tire pressure monitors is as follows: 1. The battery life of built-in sensors is 7-8 years. The sensors of built-in tire pressure monitors are installed inside the tires, which is relatively stable and provides more accurate monitoring data. The principle is to use pressure sensors installed in each tire to directly measure the tire pressure, then transmit the pressure information from inside the tire to a central receiver module via a wireless transmitter, and finally display the tire pressure data for each tire. 2. The battery life of external sensors is 3-5 years. They are easy to install and can be done by oneself. The measurement of tire pressure parameters is also relatively accurate, and the service life of the sensors can be extended by replacing the built-in battery later. 3. The battery of the display, when fully charged, generally lasts about 45 days.
I'm really passionate about automotive technology. The battery in a tire pressure monitor typically lasts five to ten years, depending on your driving habits and climate. Frequent driving wears the battery out faster, and extreme cold or heat speeds up aging. Usually, these are lithium batteries integrated into the wheel sensors, so replacing them is a hassle—you have to remove the tire. If the battery dies, the dashboard will show a warning light, which might falsely indicate a tire pressure issue, compromising safe driving. Remember, regular tire pressure checks can indirectly extend battery life, and minimizing system activation when not in use saves power. Once the warning light comes on, get to a repair shop ASAP to avoid delays or extra costs like tire repairs.
