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.

Its a great idea but physics gets in the way.

Take a look at a Malibu light 12v 300W power supply......its a brick.
I doubt that a AC/DC power supply with enough poop to power a drill
will fit in the comparable battery space.

So I think you;d be stuck "making" the low voltage DC "elsewhere" &
supplying to the tool via a cord.
Any appreciable power at lower volts require HIGH amps. High amps
require BIG conductors to minimize voltage drop.

The whole battery thing works because of the asymmetric charge /
discharge times & amperage demands.

btw I rigged up something like this to run my 12v Makita drill/drivers
off my car battery but I had to use HEAVY cables (like good sized
jumper cables). Working with them was like dragging a snake around
with me. My light weight easy to use cordless drills were now less
mobile than a corded 120v drill.

Good thing I made it out of stuff on hand & didn't buy the materials.

I think it is (was) a great idea.........but I couldn't get to work
for me.
