Is the prohibition also on "brown" shipments, aka ground?

I really don't understand what you people are all on about. Per USPS
348.22 (b), "Batteries. Mailable batteries include:
Common household dry-cell batteries such as sizes AA, AAA, C, D, etc.
are generally not regulated as hazardous materials and are therefore
mailable. Packaging requirements in DMM 601.1?8 apply.".

Generally speaking a power tool battery is made up of a group of "common
household dry-cell batteries" and so would come under this
classification.

They aren't 'common'. They use different chemistry that can easily
start fires. You don't find a 24 pack of power tool batteries for under
$10.

How does a NiMH power tool battery "use different chemistry" from an
Energizer or Rayovac NiMH that you buy in packs of 4 at Walmart?

And if you have ever taken a power tool battery apart you will know that
it is assembled from standard cells, typically 1/2AA.

You seem to be assuming that all power tool batteries are lithium ion
which is simply not the case.
