An AirTag will consume as little energy as possible from its CR2032 lithium 3V coin battery. Because of this, an AirTag will last about one year before needing its battery replaced, according to Apple.

The CR2032 lithium battery in an AirTag is a non-rechargeable battery commonly found in many electronics today, such as car key fobs. Due to the intermittent use of a car key fob, a CR2032 battery can last between 3-4 years. However, because an AirTag is always on, this reduces the battery life significantly to only one year.

Is An AirTag Battery Rechargeable?

Dissimilar to Apple’s other products, an AirTag battery isn’t rechargeable. The absence of a charging port means your only option is to replace the battery when it dies.
