Lithium batteries are high output until they're not. Like the CR2032 battery in my car keyfob it's working until it's not. The drop from 3V to 1V is precipitous

Lithium batteries are high output until they're not. Like the CR2032 battery in my car keyfob it's working until it's not. The drop from 3V to 1V is precipitously fast. Also, 1 year is extremely conservative. I normally get 3 years out of these batteries. An Airtag that's constantly being interrogated may run out faster than say a keyfob used 5x a day
- culturestate 6y agoYeah, I'd expect these to last notably longer than a year for most people. The AirTags marketing page gives the measurement spec: > Battery life based on an everyday use of four play sound events and one Precision Finding event per day. That seems like exceptionally heavy usage to me.
