Yes, AirTags do need to be charged in order to function properly. AirTags use a replaceable CR2032 lithium coin cell battery that provides enough power for up to a year of usage under normal conditions. When the battery runs low, it will need to be replaced for the AirTag to continue working.
Charging Process
To charge an AirTag, you simply need to twist the stainless steel back cover counterclockwise and remove it. Then, you can access the battery compartment and replace the old battery with a new CR2032 battery. Make sure to insert the new battery with the positive side facing up. After replacing the battery, secure the back cover back in place by twisting it clockwise until it locks.
Importance of Charging
Ensuring that your AirTag is properly charged is essential for its tracking functionality. If the battery is low or depleted, the AirTag may not be able to communicate with your device, making it ineffective in helping you locate your items. Regularly checking and replacing the battery when needed will ensure that your AirTag is always ready to assist you in tracking your belongings.
