there are no batteries as far as im aware they connect with WIFI - but no idea how if no batteries . even the spare has a sensor
Really no idea .. all i know is my Jeep mechanic said i had to replace the faulty one .. at around $600 ? forget it - why you need ? dont you look at all tyres sort of before you drive it ? a slow leak is normally discivverd the next morning .. a blow out .. well no sensor will warn of that
