BAttery capacity

[daniel]

On the battery is written rated capacity 2800 mAh, typical 3000 mAh
See image in the wiki: https://en.wikipedia.org/wiki/PinePhone#...dition.jpg

I also saw this document from Pine64 wiki:
http://files.pine64.org/doc/datasheet/pi...cation.pdf


From the factory document:
rated 2800 mAh
type (?) 2820 mAh

So, I also read 'rated' means that comes from the factory description.  Not sure what is 'Typical' or 'Type' capacity.

What is a typical capacity? why is higher than the rated? who and how is measured? Why 'Type' and 'Typical' are different?

Just curiosity in case someone knows...

thanks

The PinePhone battery build for 3000mAH capacity. However, factory cannot ensure that every battery is exactly 3000mAH due to manufacturing margin and 2800mAH is what they can guarantee.

I see... Thanks!
