This month my LS460 turned 14 years old. When I bought the car I seem to recall that I read here, or on some other car site, that the batteries in TPMS would last about 5 to 7 years. I remember when I was getting new tires put on after about 5 years that I was thinking maybe I should put in new TPMS sensors so if they failed in a year or two I wouldn't have the extra labor expense.

Well, my original TPMS sensors are all working today. I did read that lithium ion batteries are expected to last 10 years. I have no idea what kind of battery Lexus uses, but I've exceeded that life expectancy.

I'm curious, what have you other owners experienced with the life of your TPMS sensors?

My 2012's are running fine.

Shockingly, the sensors in our 2006 Jeep are still mostly good (they flake out in colder weather) whereas those in my 2007 Acura required replacement after about 8 years.

Toyota/Lexus uses Panasonic BR2450A, it is poly-carbonmonofluoride cell for high temperature applications with shelf life 10 years. I suspect, the battery lasts the longest in moderate climates where temperatures do not go too low or high where the impact on capacitance and ohmic losses is minimal.

Mine lasted around 12 years and I had Discount Tire handle the replacements plus the spare too

I suspected the batteries were made by Panasonic since my original car battery was made by them, and that battery lasted 10 years. It didn't fail, I just decided not to press my luck any further!

MY '08 - 2 were replaced in 2016 and the rest (3, including the spare) were replaced in 2018.

They are all still working in my 2011 that has been kept in Kuwait where summers are typically 45-50c. Has 100k miles and the prior owner only has paperwork for oil/filter and brakes.

My '11 LS TPMS went in '19. Probably just one. Waited until a few months ago to have new installed with new tires. Lexus wanted $40 for diagnosis and then around $700 to replace all. Got my tires at Costco and they installed new ones (5) for $135 total. They say a weak battery is generally the problem. Keep your old ones as they can be rebuilt. There's a market for them.
