Hello William:

One other consideration that comes to mind with all this, is use a
extension cord between the drill and the battery charger. You will have
to get creative to wire it up.

Hi Jay

I gave that a thought or two. About the same as running a cordless electric
razor with it plugged in.

As per your comment there are a ton of unknowns. I rather liked the idea of
the PSU for bullwork type jobs, but you are right about the high amp draw at
only 18 volts. My 1/2" AC drill is rated at something like 10 amps at 120V so
that's about (120/18*10)= 60 some amps by comparison on 18 volts. Hefty
draw!!

In any case it all seems like a can of worms and not worth doing and if I
factor in that replacement batteries are ,, while not cheap, at $108 for two,
they are a lot cheaper then full price here. I think that's the way I'll go.

Thanks for the ideas

Bill



The Battery charger may not run the drill motor, but will keep the
battery charged up, somewhat. The wire I would use would be just light
Zip Cord used for lamps and stuff, available at hardware stores.

The resistance in the wire will limit the current, protecting the
battery charger I am thinking. I don't know how much current the drill
motors take but its probably high for starting and sinking wood screws
and such down, and of course thats where the battery comes in, supplying
the high current. As the drill would be off most of the time, it would
allow the battery to be charged.

I am thinking that the drill motors may take as much as 20 amps of
current for the peak usage. So that would require a 18 Volt DC power
supply, at a current rating of 20 or more amps. And the wire it would
take would be something like 12 or 10 gage wire. So now you have a
expensive power supply and are no longer wireless.

Hello William:

I have given up on the battery operated drills. They are in a pile of
drill motors and batteries. Maybe ok for the weekend fix it guy who
wants to hang a paper towel holder.


I am coming around to that point of view as well, but damit they are so
darned handy!!
