> we recommend Energizer Ultimate Lithium

The advantage of "lithium" is high rate discharge, not longevity right?

They don't leak would be why I would choose these over an alkaline battery. The draw of an airtag is so low that the shelf life becomes very material.

I also put lithium AA/AAA batteries in remotes these days - anything that might get stuck in a drawer for years at a time and needed again for a random task. My A/V receiver remote is rarely touched, but when I need it I really need it. Too many times have I went to grab some device like that only to find the batteries have leaked and corroded a critical component on the PCB.
