I managed to fry one of the batteries to my DeWalt 18v drill , and I'm a
bit confused ... My batteries are model DC9098 . I find all kinds of
replacement batteries , and one of the most common is a DW , not a DC 9098 .
I see a difference in the A/Hour ratings , and wonder if this is the
difference in the letter designation . I'd match the battery to the model of
the drill , but the tag with the number is damaged . I've been a fan of the
Dewalt drills for over 20 years , and until now the only battery failures
I've seen were due to not completely draining them to dead before charging .
I had a 12v battery last over 6 years ... but this 18v unit died the other
day while I was using my drill to mix mortar for the stone work behind my WB
stove ... got hot , then nothing and now it won't charge . And I gotta have
a 2nd battery , one to use while the other charges .

Running batteries to "dead" is the worst thing you can do to them.

Not NiCad's , they'll never take a full charge again if you don't
discharge them fully before charging . I and a coworker both got identical
new drills at the same time . He would slap a fresh battery in as soon as
his slowed a little , I'd run mine all the way down . My batteries lasted an
average of 4+ years , his were being replaced on average in less than a year
.

Different strokes. I do it like your buddy does and I have several
packs that are nearly 12 years old and work fine. If you take them down
much below 1.1V/cell you are not doing them any favors. Your drill may
refuse to run before you get there. Thus your good fortune so far.

If you discharge nicads fully, some of the cells get reverse charged, offgas,
and quickly die. You should only run the battery down as far as you can without
risk of reverse charging a cell.

In article <WkfSv.276092$oh4.1...@fx11.iad>,
The problem with "all the way down", is that after a cell gets to zero
volts, continued current flow will reverse charge it. Your 4+ years
batteries probably had well matched cells that all discharged at the
same rate.

When I have trouble with my 18V batteries, I take them to "Batteries
Plus". They refill them with the higher A/Hour cells. The refills are
less expensive than DeWalt, and seem to last longer.

Don't know about the refiles, but it seems that youcan get a new drill,
charger and 2 batteries for the same price or less than 2 batteries.

They will be made in China though...maybe some in Japan left (Makita, Panasonic).

I have some 10 year old cordless Bosch tools ( a 5-piece set ). I
have corded tools to mix paint, mortar, etc. Usually heavy demands.

I bought the Rockwell 3Rill for small jobs ($99.99 for three equal
payments) around the house - not the complete kit as I have tons of
bits, drivers, etc. They fit the chuck.

It would cost me ~$160 to rebuild the Bosch (3) batteries. It was
simple common sense to buy the Rockwell 12.V. For me.

- High torque impact driver, dual-speed VSR drill & screwdriver
- Works in tight spaces & awkward angles where others can't
- Screwdriver-mode features 22 clutch settings
- Utilizes quick-change and traditional bits
- Includes (2) 12V LithiumTech batteries for lasting performance

And impact mode.

Batteries are free for the life of the tool. Buy online get an extra
year warranty for the tool.

If I needed a cordless now, I would look in to that just because of the free
batteries for life. I have an 18 volt Dewalt and the batteries seem to be
in good shape. I don't use it very often,so they may go bad because they
are not used much. I do charge them a couple of times a year.

Yup, I did that last time Lowe's had them on sale for $99. However, you
get the smaller batteries. That's ok for me because they are certainly
lighter in weight. With the way I use them, I've not noticed a problem.
And the big plus for me is that I think my old charger was over
charging (in a trickle mode after the light goes out) because the
battery always remained warm while on the charger. The new charger with
the drill kit, doesn't do that.

Lithium batteries are smaller/lighten, charge more efficiently...last at least at long. Possibly what you have?

Definitely not. DeWalt does have a smaller NiCd battery with a little
less capacity, lighter in weight and slightly smaller in size. I wish
they did have a LIon replacement for the 18 volt DeWalt batteries. It
might be nice.

http://servicenet.dewalt.com/Products/Detail?productNumber=DC9098
says you have an 18 V, 1.2 amp-hour NiCd battery. That site doesn't
know about the DW9098 model/part number. I suspect the "DW" is an
aftermarket designation for De Walt.

For a given cell size, you usually have a choice of at least a couple
of amp-hour ratings. The aftermarket people are probably advertising
the higher-rated cells. Some of them are probably even *installing*
the higher-rated cells. If you're really lucky, they had a good set of
orphans working the line at People's Shining Battery Factory #39 that
day, and you will actually get the stated rating.

If you go here
http://servicenet.dewalt.com/Products/Detail?productNumber=DC9098
and click on the "Part # N143312" link, you get
http://servicenet.dewalt.com/Parts/Detail/311758
, which says that this battery is used on the "DC970K-2 Type 1 18V
Drill", "DCK235C 18V Drill/Imp Combo", and "DW959K-2 Type 2 18 V
Drill/Driver", if that helps any.

I bought the $100 DeWalt drill-driver kit, and a spare 12 V NiCd for it,
at Home Depot in 2007. By 2012 both batteries were pretty tired, but I
could still get some work done by juggling them on the charger; by 2013
the batteries were pretty much gone. In mid-2013 I got both of them
rebuilt with new NiCd cells at Batteries Plus for about $35 each, out
the door. I figure 5 to 6 years of use for $35 is not a bad deal.
Also, they at least say they recycle the old cells in some acceptable
manner.

It might be worth calling your local Batteries Plus, if you have one,
to ask. I had to drop mine off and come back a few days later. I've
been using them since then and they work fine.

Standard disclaimers apply: I don't get money or other consideration
from any companies mentioned.

My Dewalt drill smells like ozone & sparks a lot.
But it still works.

Why does it smell like ozone?

Normally because the commutator is arcing.

That's what produces the sparks.

Agreed! I just replaced the brushes on my old chop saw. It went from
noisy sparking, smelling with no power to "like new". The brushes looked
worn, so it may not last. But I went for 10 sets of brushes for $12,
rather than the official ones for $20 for a set, so I can replace them
again.

FWIW, the top motor on previous car, or the one before that, probably
that one, the '95 Lebaron, got so bad the top would not go up most times
unless I opened the trunk and whacked the motor with a heavy wrench.
Then I had to whack it 3, 4, 10 times and then it didn't work at all.

I'd been looking for brushes and at the hardware store he had an
assortment. My size was maybe $4 a pair and I took the motor out and
apart, and then I saw that, though the brushes were the same size, the
braided connector on what I'd bought was much thinner. The motor used a
lot of current. I didn't want to do without the convertible top until
I could mail order better brushes. I thought about stretching the
springs but I don't think that would work well,, so I balled up tin foil
and put the brushes in their slots on top of one foil ball for each, on
top of the spring. It was fine for another two years until the car
failed for other reasons.

Well, it's still my train, even if I haven't played with it for 60
years. (Someone at a hamfest gave me extra track only 15 years ago!)

I should have sold it long ago when it would have brought money, but I
guess we were sort of saving it for my nephew.
