Why not offer a CORDED battery replacement?

If the battery poops out, you could continue to use the tool with a
cord - much like you can with a cell phone.

The working parts business of battery charger that comes with the
tool is smaller than the battery itself, and could easily be fitted
in a case the size of the battery.

In the alternative, why doesn't some clever entrepreneur concoct the
device to sell as an after-market product? Certainly non-OEM battery
replacements are available; why not power-cord replacements for the
battery? Heck, I've got some old batteries lying about, I might
just try
building a small DC power supply to fit in the scooped-out innards
of one. Just thinking out loud.
Why not use one of those old fashioned drills, you know, the ones you
plug into the electrical outlet in the wall?

Quiet. These guys are re-inventing those.

I hear they are having problems with the AC batteries.

Years ago, an electronics teacher I had, told a story about
one of the many pranks electronics geeks will play on each
other. I'm guilty of quite a few but the prank the teacher
told about was brilliant. There is always some smart ass
who tells the new guy to go get an AC battery off the shelf
in the back. Well, it was pulled on a new guy who was fresh
out of tech school and of course knew everything. Well, he
was told that AC batteries were a new item and that there
was one on the shelf. The skeptical young man went to the
back and sure enough, there, on the shelf was an item labeled
AC battery. He took it back into the shop and handed it to
the senior tech while saying that they were pulling his leg.
The prankster told the newbie to watch this. When the battery
was connected to an oscilloscope, it displayed a nice little
1.5 volts peak to peak sine wave. The guys in the shop had
installed a little battery powered oscillator inside the empty
casing of a D cell. The old regular D cells were basically a
zinc can with a carbon rod connected to the + contact and
they were relatively easy to open up and clean out.

Good one! Especially the sine wave! We charged up caps to a couple
hundred volts, threw them at the new guy and said catch.

Let's see some of the pranks I would pull. In one shop where
I worked, our workbenches had a master switch that we would
flip on when we sat down to start our day of toil. #1, paint
the guy's soldering iron with liquid flux then coat it with
gun powder. #2, Take a bunch of 12volt miniature lamps and
hook them to the 120volt power so that the sun came out when
the victim flipped the master switch on his bench. #3, Swap
the contents of the tuner wash and freeze spray cans. I would
pull a vacuum on an empty can then connect them together with
the plastic extension tubes and transfer the disparate content.
The victim would get an unexpected result when trying to clean
or cool something. #4, The old add a handful of extra hardware
to the tray holding a disassembled item trick. There are many
more pranks that a bunch of warped, bored, creative people
would pull on each other.

TDD

About the spray cans, the freeze spray is expensive and canned air for
blowing the dust out of computers is cheap, especially by the case.
Just hold the can upside down and you have freeze spray. I also hook
them together when a can of paint somehow lost most of it's pressure.
Hook up a canned air can (upright) to the paint can and pressurize it again.
