I saw a Ryobi tool case thrown out during the city's special pickup
last Friday night. It was hefty, so I took it home.

When I finally opened it up today, I found a Ryobi HP62 6.0 volt
cordless drill inside. It looked absolutely brand new. I mean, really,
it looks as if it has never been used at all. All the bits save one
were there. I figured, "let's charge it up." That's when I noticed
that the wall wart in the drill case was from an AT&T answering
machine or cordless phone. The AT&T charger has a 9vac output. Hmmmm,
I wonder if that's why the drill got thrown out.

After some searching, I found a Canon 6 vdc, 300 ma charger, probably
from an inkjet printer, that charges the battery pack, but not any too
fast.

The proper charger for the Ryobi is a Ryobi-Ridgid part 7221001. I
don't know what its output voltage or current is. If anyone has one of
these chargers lying around, I'd like to know the specs on it. I'm
sure that in my massive collection of wall warts I have one that's
close enough.

Thanks.

Here's what I do:

Put a moving coil milliammeter (multimeter) in series with an adjustable
wall wart. Set the polarity for the highest current on the lowest voltage
setting, then up the voltage until the current is what I consider
reasonable. Let it charge overnight, adjusting the volts up as needed.
Generally this will give you a full charge and will give you an idea as to
what voltage charger to use.

Given the OP's implied level of experience, advising him to "up the voltage

NiCD batteries are pretty forgiving. What I would do is use a 12V or so wall
wart and put a resistor in series if necessary to limit the current. IIRC if
you take the ma/hr rating of the cells and divide by 10, you get
approximately the charge current you want. It's not too critical though,
slower charge is easier on the batteries but takes longer.

It's a practical method. Failing that, he needs to buy the right charger.

Ryobi's use a really simple charger,just a wall-wart with a diode

I've been given or purchased cheap many an item missing its charger. This is
the method I use. I usually aim for 1 or 2 hundred mA of charge current.

Before posting at s.e.r., I Googled for the item. It is sold at a few
online tool dealers. None of the few links I checked gave a view of
the charger, and none had any details regarding output current. I
figure if I called Ryobi, the person answering the phone would know
only how much extra the shipping would cost, and how to take credit
card information. Home Depot is a five-mile drive. The person there
would liklley not know how to read the information on the charger.
Thus it seemed logical to ask here, in the belief that someone at
s.e.r. actually owned one of these drills and could quickly provide
the answer.

There is a six volt Ryobi drill/W charger on Ebay right now.

If its the same tool, email the seller to ask the seller what the
charger is rated at. I don't have an Ebay account, so I can't contact

A quick Google search for the HP62 gives the parts listing

I didn't buy them, they were given to me. Shoddy workmanship, and low
quality, even for China. I got two drills, a case, a flashlight, a
buffer, seven 18 V batteries and six chargers. One drill had a wire to
the trigger than had never ben shoved into the slot, and the other had
the shaft that held the chuck sheared off.

A drill with a keyed chuck. I still have the 1/4" B&D I bought in
1970. Its been used on construction sites with 24 feet of diversibit to
pre wire buildings, and to install sound systems, MATV and alarm wiring
in existing buildings. I've drilled from the attic of a three story
house, into the basement. I've had smoke pouring out of it, and it was
so hot that you couldn't hold onto the aluminum casing. I'd let it cool
for 15 minutes, and go back to work.

Think about it. Have you ever seen a commercial drill with a wimpy
keyless chuck?

A label on the drill itself says "Use with Charger No. 7221001." When
I enter that p/n at www.m-and-d.com/ryobi_tools.html, I do not get the
specs for the charger. The only description is that it is a charger.

The tool is Chinese-made. I scavenged a Chinese-made Ikea lamp a few
weeks ago with a bad crimp inside. It looked like a good crimp, but
the meter said otherwise. There's a lot of brand new-looking Chinese
stuff in the trash around here. All of it is so cheap that people
throw it away rather than attempt to fix it.

Walk around Bed Bath & Beyond some time. I don't think there's
anything in that store that's American-made.

I still have my 1/4" B&D drill that I bought in 1969. I refuse to buy
Chinese stuff.

I don't know what you'd make the windings out of to achieve this - copper
will melt. The cheap and nasty way is a series resistor.

Better get the OEM replacement for a certain match. Problem is, the specs
on the charger unit specify output volts, amps and AC or DC but not the
internal resistance of the unit which can vary. If you get one that seems
to match but has low internal resistance, it may not properly taper off the
charge at the end of the cycle leading to an overcharge and possibly battery
damage. The quoted price is about as low as you are apt to find anyway.

If you want to reply via email, change the obvious words to numbers
and remove ".invalid".

Better get the OEM replacement for a certain match. Problem is, the
specs on the charger unit specify output volts, amps and AC or DC but
not the internal resistance of the unit which can vary. If you get
one that seems to match but has low internal resistance, it may not
properly taper off the charge at the end of the cycle leading to an
overcharge and possibly battery damage. The quoted price is about as
low as you are apt to find anyway.

the cheaper cordless tools(like Ryobi) use a plain transformer charger,not
some regulated "smart" charger. And you CAN overcharge your packs with
them.

Some folks use a simple timer to shut off the charger after 8 or 16
hrs,whatever's called for by the particular tool.

the better tools use a one-hour or shorter fast charger.
They also have a temp sensor in the pack,or use an IC to monitor battery
voltage to determine when to stop charging.

Miniature?

Similar to Dremel, but cost rather less - and I'm not sure Dremel had a
cordless option at the time I bought it from B&Q, over 5 years ago.

Model #?

HTC-18 4.8v 19W 16000rpm

Pics?

Can't be bothered - do a Google. ;-)

It's had heavy hobby use and even the batteries lasted well. They are AA
size so cheap and easy to change.


Dremel has had a cordless hand grinder for more than 5 years.More like 10
years.

harbor freight has one that runs off 12VDC,comes with an AC adapter,or you
can run it on your auto battery.(or 8 D cells)

And five years is hardly elderly.

My Black & Decker AC drill turns 32 years old come December, a significant
percentage of my life, and the only upkeep it's needed was replacement
brushes about 1990.

Even my Sears "rotary tool" is at least 15 years old, and I wouldn't call
it "elderly".

They weren't around in the UK when I bought the Ryobi - or at least not in
the DIY stores.

Err, something that needs 8 D cells isn't in the same class. This is a
small light high speed drill. I mainly use it for PCB work. It uses 4 AA
Ni-Cads and is only about 9" long - little bigger than a mains Dremel.

Very much so if they say something like a four hour charge. At worst, some
have only a series resistor to set the current - even although they
provide a pretty LED to 'show' it's charging. The series resistor idea
isn't quite as bad for a lower charge rate like say overnight - but can
still cause damage through gross overcharging. However, as the cost of
'smart' electronics comes down, some cheap ones are providing it. If only
to cut down on warranty claims.

But these aren't cordless. Most inexpensive cordless tools get junked when
the battery pack fails as a new one is often priced at more than the
complete unit - as are replacement cells.

I can beat your B&D - mine was bought in '62. It did have a factory
overhaul some 10 years later then got a more gentle life used only in a
drill stand. Don't think I've used it since I got a pillar drill - these
days you get used to soft start vari-speed mains drills which reverse, etc.

I have one of those. I got it used at least 17-18 years ago. At that
time it had done hard service in a luthier's shop and needed work on the
speed control and new brushes. Sears had a hard time coming up with a
diagram, but finally was able to order parts for me.
