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.
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

here or on the metalworking newsgroup just recently.
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)
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.
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.
Gee if you're in the 'states' , goto your local Harbour Freight and buy
their 9.6 volt battery packs for $9.00 !
9.6 Volt Battery
Works with 3/8'', 9.6 Volt cordless drills, ITEMS 45934 and 45933. . 1.3
Ah . 8 Cell
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
It really costs MORE for 'official' battery packs than NEW drills.......

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.
The other option is to get another drill with the same battery pack. They
usually come with 2 so you can use both at the same time or one while the spare
is charging. My wife and I have his and hers Makitas.
That is sometimes handy when you are drilling and driving screws.
