What “brand” battery is supplied with a new AirTag.

no one is answering ‘the question’, instead, telling me what size battery, and what brands mfg. them.

It’s so funny, someone asks a specific question [not just me mind you]. It’s like they never read, nor understood the question. Perhaps seeing ‘AirTag’ and ‘battery’ was enough to answer in your own way.

This question was asked before mine. One had advice to clean the ‘bad taste’ chemical off for it to work.

i guess i gotta’ go buy one and open it.
