How long does an AirTag battery last?

Got AirTags on my keys and in my suitcase. How long before the battery dies, and does the phone warn you when it's getting low or does it just stop showing up?

about a year, a bit more if it rarely moves. Find My shows a low battery warning before it dies. It's a normal CR2032, push down on the back and twist anticlockwise to open. one catch: some CR2032s have a bitter coating (the child safety ones) and those can fail to make contact in an AirTag. if a new battery does nothing, try a different brand.
