I did a Google Internet and Groups search on the above string but couldn't
find this question discussed anywhere.
Sometime ago I bought a 9.6 volt cordless drill. Now the battery doesn't
want to stay charged. A new battery is as much, or more than, a new drill.
So I was wondering if any clever person has worked out an easy way to
convert a still good cordless drill motor to one that is corded, thereby
cheating the battery game.
Thanks for any help.
Robert
I thought about that for my 12 volt drill, I was thinking I could then run
it off a car battery or battery charger

Hum...that's odd... I seem to recall this coming up either
here or on the metalworking newsgroup just recently.

This certainly can be true.

In short...no. While battery powered drills are great things,
they have rather less power than most tailed tools. Losing the
portability factor does NOT make it a better tool. Now..there are
a few different ways to make it useful.
1) Drop some serious bucks on a 10V wallwart, and, after
pulling the guts out of one of the defunct battery packs, attach
the power supply to it, to adapt it to the drill, and, use the
drill as a corded unit. It will probably have to produce a couple
of amps or more, so will not be cheap...or light.
2) Take the battery packs to Batteries, Etc and have them
rebuilt. That will likely be much cheaper than replacing, and
will not lose you the strength of these tools - their portability.
3) Cut the battery packs apart and, replace
the cells in them yourself. Probably the cheapest way, although
the more labor intensive.
4) Bundle it up, take some pictures, sell it on Ebay and
buy a new, 18V unit that will twist your arm off. I suspect if
you put words like "Unique", "special", "collector's special"
and that sort of thing, you likely will find someone to pay
more than retail for it (he said, bitterly, having been outbid
a number of times recently)

I though I saw a place that stuffed switch mode power supplies into old
battery packs. Certainly get plenty of power this way.

Here is one for a Dewalt. I DAGS with "cordless drill ac converter" so
you might try it as well to find something that will work for you.

I bought some of these to refurbish my dying 9.6 Makita packs. Install
was easy enough but they died after only a couple of charges. I'm
guessing they are not compatible with the Makita charger and I'll have
to use a wall-wart style trickle (24 hour) type charger.

I've been thinking about doing this too since I have 4 cordless
drills that wont hold a charge. My plan is to buy a cheap switching
PC supply and attach it to my workbench and use the 12v supply to
power the drill(s). These supplies can be picked up pretty cheap
(a 500 watt supply on pricewatch.com is $13 delivered) and can
handle 10+ amps on the 12 volt supply so I think it will handle
it Ok. It won't be portable but all I really want is to be able
to use these drills on my workbench (I have other corded and cordless
drills for mobil usage). If I end up doing this, I'll let you know
how it worked...

I like the car answer.
Otherwise, go buy a cheap drill. This is a time loser, and I'm a big
scrounge. Good DC supplies are expensive and a lot of trouble!

That will make it turn but little more. These supplies can not deliver the
amperage to produce any power. If it's a good supply, it will shut down. If
a cheap one, it will burn up.

a bridge rectifier and transformer may fit into the old battery pack, along
with a circuit board and a few electrolytic caps and a voltage regulator,
shouldn't be hard. Pick up a circuit diagram at Radio Shack along with all
the parts.

It will be tough. It may only take 9.6 VDC but the motor will draw lots
of amps. I would not be surprized if peaks of 10 amps are common.
Those little power suplies just won't handle it.

Now for this application what you need is a charger permantely wired to
the battery. That way at a job site where there isn't power you can run
it without plugging it in. Then when there is power the battery will
charge some in between cuts. If after lots of cutting the batter is
getting week then just go do something else for a while.
Now as for how to acomplish this. Open up the tool and add a small
power plug like a headphone jack to the tool. Not the battery.
Batteries do go bad. By modifying the tool you get to replace the
battery when you need it. Then take an old battery of that will fit in
your charger. Take it apart, remove the batteries and attach a cord
with the correct plug on the end. This way you can use your existing
charger.
The only mod to the tool is a small (3/16) hole. Then install connector
and wire in parrallel with the battery connection. Use at least 18
guage wire to connect the connector to the battery contacts. Then use
at least a 18 guage power cord attaching the modified battery to the
plug. What you want is an 18 guage path from the charger through the
cable to the tool. Otherwise the quick charger might not work. Quich
chargers often generate over 1 amp of current and have to measure the
voltage at the battery to tell if it is charged. You need really good
connections so that the charger works properly.
Then lets say you are making a 10 second cut every couple of minutes.
The battery should never get low.

What a bunch of well though out baloney LOL :-)

I love it. Only in America would we pay a premium for a cordless drill
and then drop another $140 on it to make it run from a cord.

Use a trebuchet. A few good hurlings of the cordless drill, then you
will obviously have to go and buy a corded one, no questions asked.
Converting one into the other just isn't sensible.
Gee if you're in the 'states' , goto your local Harbour Freight and buy
their 9.6 volt battery packs for $9.00 !
details...
9.6 Volt Battery
Works with 3/8'', 9.6 Volt cordless drills, ITEMS 45934 and 45933. . 1.3
Ah . 8 Cell
ITEM 45943-0VGA
...
OK, you'll have to cutoff the case,resolder the batteries, but man what a
nice,easy solution !
I'm surprised they're not on sale(usually they are $4.99 )!!!
I wouldn't mind 4 or 5 sets to replace my 'dead' Makita and Craftsman
drills.
It really costs MORE for 'official' battery packs than NEW drills.......

I have one of those Makita 18v cordless sliding miter saws, and I

how much current the motor would pull. I don't use the saw very often,
and I usually have to recharge the battery every time I break it out.

You would need a converted to step down the 110v AC to 9.6v DC and
adapter that to run the drill

And building and using a trebuchet is just damn good fun too. Highly
recommended!

Radio Shack sells power supplies that produce different voltages, some are
variable. Find one that will produce the correct voltage. You may get
lucky and have the power supply fit inside an old battery casing.
I don't think I would go to the effort thought.
