Although these TPMS sensors have never been fitted to a vehicle and can be considered 'new', they were very old in time. Three of the four I bought were 10 years old when I bought them! Unlike some other batteries that have a 10-year shelf life, the lithium-ion batteries in these sensors begin to degrade the day they are manufactured, even when not in use. The packaging was also deceptive as it looked like a real Motrocraft. The gift is a statement "wrapped in 2017", not "manufactured in 2017".
