Does tpms have batteries

Yes, Tire Pressure Monitoring Systems (TPMS) can have batteries. There are two main types of TPMS: direct and indirect. Direct TPMS uses sensors located in each tire that typically have batteries to measure tire pressure, while indirect TPMS relies on the vehicle's ABS system to estimate tire pressure and does not require batteries. The batteries in direct TPMS sensors usually last several years but may need to be replaced when the sensors are serviced.
