Repaired? Not usually, unless you want to attempt it yourself by opening the
case and seeing if the batteries inside are a common enough type to be
replaceable. There are some companies that offer rebuilt battery packs -
try Googling for them.
As to cost...."too high" is in the mind of the poster.
You may find your local batteriesRus type store may be able to rebuild
it cheap. You can also buy a new battery. However depending on the age of
the drill and the quality of the drill, you should at least price out the
cost of a new drill and maybe a upgraded model. Those batteries are
expensive. I just upgraded my 12V drill for a 18V with more features and a
lot more power for just a few dollars over the cost of a new battery. Look
for sales on the new drill, the old batteries are not likely to go on sale.
He could get an estimate from a store that does battery rebuilds.
He could take the model number of the drill/batt.pack to Sears and see what
a new pack costs.
Then he could determine whether it's worthwhile to repair or replace the
pack,or go for a new drill.(hopefully with TWO batt.packs)
I hope he has better luck with the "drillmaster" drill- the harbor freight
bottom end drill- than i did. while the drill itself is ok (i bought the 12v
and discovered that the thing had space in the pack for 2 more cells), the
batteries themselves self-discharge at a surprising rate-2 days from a full
charge to nothing.I bought a bunch of the packs on sale and was going to use
the cells to rebuild other packs. It didn't work that way- first the cells
were 1300mah cells- pretty feeble in comparo to the 1800-2200 mah that the
typical sub c cell, second, they didn't take kindly to the 9.6 makita
fastcharge(the drill I bought the additional packs for). After a couple of
cycles, they were dead to the worldI ended up buying surplus cells from an
electronics surplus place that were out of date but still held a decent
charge. If I'd bought the cells from "batteryspace.com , I woulda paid
pehaps twice the price than the surplus cells. which were double the cheapie
drillmaster cells- but they would have been matched and 1800 mah. There's a
big variety of cells that are useful- some are meant for fast charge, some
aren't, some also have a higher self discharge rate than others- then
there's nimh cells that are better than nicads when it comes to power- up to
3000mah) for the same size cells but may not take the same # of cycles
before they're ready to be "recycled".I read of one estimate that nicads
will go 1000-1500 cycles before they're "dead" nimh are 500-1000 cycles and
the latest lithium ion cells possibly less than 200 cycles before dead. What
bugs me is the trend to shitcan the drill when the packs call it quits
because the tech has improved in the new drill (more features, less weight,
more power). We're tossing a lot of material ...because of the "cheapness"
of a new one. Pat
Hey are those the old 7.2 (3.6) round tubes batterys?I could use them if you
don't want them. Also need a old stanley 6.0 volt for a switch that no
I took a defective 18 volt craftsman into sears a couple months ago..
they no longer had repalcement batteries for it. the newer 18 volt
packs are differnet and won't fit. Ended up buying a new set. Got a
perfectly fine drill that I habe no battery for. How do these packs
open ? seems all sealed to me.

Did you try the on-line (or local) Sears parts store,where you get
replacement parts for Sears products? Or just walk into a Sears store and
ask a clerk? All they know is what's on the shelves.(if that much)
Battery pack plastic bodies are usually heat-welded.Takes some work to get
them open and still be able to re-close them.
Buying a new drill/battery/charger is almost always a better choice. That's
assuming that you don't have a fairly modern, high-voltage, top-of-the-line
drill. Purchasing an individual replacement battery is expensive.
On the low end, you can pick up a drill/battery/charger combo at reasonable
voltage under $20 from Harbor Freight, Homier, etc. Even if you have to order
on-line and pay shipping, it is economical. The batteries will usually have
less capacity then higher cost units - this is due to intentional slight
undersizing or to lost cell capacity do to the age of the units. Not a big
problem. I have friends who have walked into Harbor Freight and bought 6 or 8
cheap drills because they cost just a few dollars more than the cost of the
battery packs. This way they've got extra drill bodies and extra chargers.
I've got a very comprehesive Black and Decker 14.4 volt setup with many tools,
batteries and chargers. I've watched for great sales and closeouts on this
system. For example, I bought one extra case, drill, light, charger and two
batteries for much less than the list price for just the 2 batteries.
As for your existing drill and battery: It usually isn't that difficult to cut
open the existing pack and replace the cells inside. Sometimes you may need a
dremmel tool to fit generic replacement cells inside the case if the
manufacturer purposely used non-standard sizes to prevent this. Sears is one
culprit for such games. The same advise goes for cordless phone battery
packs - often one needs to "Dremmel out" bits of the handset interior to fit
in replacement cells which are slightly larger than the intentionally sub-sized
originals. Any battery pack can be replaced - it's just a matter of how
difficult the manufacturer intentionally made the task, how handy your are, and
the value of your time.
I hope this helps.
Harbor Freight has drills with rechargable batteries. Soemtime down about
$15 for a drill and battery and charger. They also have replacement
batteries. I got two 12 volt drills, $15 each, and a couple batteries $10
I have long since earned back the cost of the drills.
I doubt it's cost effective to repair it. Even the replacement batteries can
end up costing more than it's worth.
My good rechargable drill is a Makita, and I'm very pleased with it. One
friend uses Panasonic, and he's very pleased with that.
