We have Tire Pressure and Temperature Sensors on all of our vehicles and RVs. Last week one of the sensors failed after a year. I figured a battery
failed and expected the other three would soon follow. It turns out I had three of the require CR1632 batteries. I replaced three and they all worked. Since I needed a fourth I went out to buy one, locally hard to find but I got one at CVS and paid $5.99. Yikes.
I went home and went on Amazon and found 10 German manufactured 1632 batteries for $5.99 including shipping. Amazingly one tenth of the price.
