Where is my key?
Have you ever seen where I put my backpack?
I think many of us have experienced losing something. It has become a daily thing for modern people. In order to help users solve this problem, as we all know, Apple launched a wireless tracker AirTag in April this year. But the other problem is What Should We Buy to Replace the AirTag’s Battery? Today, let me answer your question.
What type of battery does AirTag use?
In the previous article, Apple AirTag Wireless Tracker’s Battery - CR2032, we have talked about what kind of battery that AirTag is using, which is the common 3V CR2032 button battery.
But what is the CR2032 button battery? Different countries and regions have different naming standards for button batteries, but there are still rules to follow. Take the CR2032 button battery as an example, C means the chemical battery system with lithium metal as the negative and manganese dioxide as the positive, R means that the battery shape is cylindrical, with the diameter in 20mm and the thickness is 3.2mm. Users only need to pay attention to the voltage and size of the button battery. If they are the same, they can be used.
