Some smart batteries store their manufacture date, which is
useful to identify the battery and/or to know about the cell
quality.

Have you considered exposing this as a single file? Say following
the ISO8601 format - YYYY-MM-DD.

Yes. My initial implementation was exactly that. The thing is, that
I suspect some fuel gauge implementations may only expose the year
or just year + month. I chose 3 files, since receiving 'YYYY-MM'
instead of full ISO code might be more unexpected than not having
the DAY file available. But I don't have a strong opinion on this.

Fwiw the ISO 8601 allows for YYYY-MM, although you're spot on. Having
the three fields separate makes perfect sense.

Thanks
