I've run a 14 volt drill with a 12 volt battery....has anyone
run an 12 volt dewalt drill with an 18 volt battery....I have
two 12 volt drills but would like to use the more powerful batteries.
Thanks

That sound you hear is your drill's motor burning up.

No, it's the smell. That's a 50% increase (12 to 18), so it
won't take long.

Wonder if his real name's Tim Taylor? g

Actually, it's a 125% increase. Power at a given resistance is a function
of the square of the voltage. (P=V^2/R)

Some tool makers use different contact configurations, so that you can't
over volt a drill. 18 volts in a 12V drill is a bit too much. I wouldn't.

Most likely there would be no problem. The limiting factor is the size of
wire their used in the motor. I devised a way to use four batteries for an
old two battery screwdriver. Worked wonderfully.

Right. I've run double and triple the rated voltage on DC drills. I've
abused them terribly and almost never burn up a motor because of it.
If you check the motor manufacturer's specs you will see that the
motors are rated for quite a range of voltages. If you have a source of
donor parts or the drill in mind is expendable, then have fun and go
for it. Custom made tools are great.

The motor may handle it but you have electronics and gearing to
consider, it seems everyday products get cheaper, so do the internals.

I doubt that for those voltage (6 to 18 volt) the electronics should not be
a problem. The motors and electronics may well be the same for all units
from a given manufacturer. And the electronics doesn't amount to much of
anything anyway. Not even as involved as variable speed AC motor drives.

The electronics amount to everything if they blow.

I bet. I'll also bet you didn't use ballasts to balance the
batteries, and their life was awfully short, but then it
"worked", right?

replying to Pop, Jason wrote:
Ballasts are not used with batteries. Very creative but irrelevant. Batteries
connected in series don't need balancing. In any case, the issue here is the
use of an 18V battery module with a 12V tool. There are adapters available
online to do this. Whether it works well for a particular tool will depend on
the design of the tool..

They are likely throw aways anyway, so if they fit, have at it. It
will NOT likely harm your battery.


This morning, I took one of my 16.8 volt drill batteries apart and
found the bad cell and replaced it with a cell from a 9.6 volt battery
(which I had trashed because it had a bad cell also). It works
wonderfully, even if the battery was smaller in physical size than the
16.8 batteries.

I have found the batteries to be too inconvienient to use, regardless
of the voltage. So, I went out and bought a new Dewalt and wired it
directly to the 120v house current. I also built an adaptor for it so
that it runs on 240 for those really tough jobs.

Matt get a transformer 480v works best.

Hey! I never thought of that. Will do!!!!!

Folks, Matt and Ransley here just might be dumb enough to plug therir
DC drill into the AC socket or an AC transformer, but trust me it will
blow your circuit breaker very fast. Sometimes it will blow so fast
that the drill will survive it.
You can use an AC step down transformer that will put out 10 amps or
more, but that's expensive unless you already own one. A DC drill
operated in this fashion has no where near the power (watts) of a low
cost AC drill with a cord. There are ways to beef up your DC drill.
However, don't listen to these fools. They have not done anything
themselves.

WHAT you mean my 3.6v B&D cant take 440 AC so far it works great ! Gee
Ive got 3, 220 - 110 transformers from Europe and I was just going to
inline one more for 880v AC. Aw I gonna try it anyway an 880v ac B&D
Kick ass.

Howabout an 880v coffemaker , makes a pot in 6 seconds flat. And my
slow ceiling fan, yep 440 just might do it there also.

Well, if you get a dewalt cordless drill, and then build an adaptor for it,
to run on house power. Havn't you just reinvented the electric plug in
drill?

Yes, only better. Nobody ever had a 240v cordless corded portable drill
before.

Im tired of electric, im putting in my RC cars 35000rpm nitromethane gas
motor and clutch in my drill, now thats power to screw.

Been a long time since I"ve had this much fun just TALKING about
screwin'!

Well, gotta go look for that xfmr now. Hmm, think I had a
conductformer somewhere, now where did I put that?

Oh yeah: They're called stationary 240V cordless corded
mini-portable drills!

I have a 14.4 Makita drill can I use a 18 v battery in it

He can if it fits. AN old friend built a Zenith 601 airplane with a
7.2 volt drill run off a 12 volt car battery - and that is a LOT of
1/8" holes!!!!
