HERE IS A SIMPLE RUNTIME TEST TO SEE HOW MANY HOLES PER CHARGE FROM DEWALT’S DC9180 XRP LITHIUM ION, DC9096 XRP NiCd BATTERY, AND THE DC9099 COMPACT NiCd BATTERY.

THE DEWALT DC9099 (1.7Ah) DRILLED 88.5 HOLES, OR 52 HOLES PER Ah.
THE DEWALT DC9096 (2.4Ah) DRILLED 121.5 HOLES, OR 52 HOLES PER Ah.
THE DEWALT DC9180 (2.2Ah) DRILLED 124.5 HOLES, OR 56 HOLES PER Ah.

Did you do a test with the DC9181 18v Lith Battery that comes with the DCD760KL (Standard Battery). Dewalt doesnt ship a kit with the DC9180…my opinion a mistake but it is heavier (.65lbs more than the DC9181 making the DCD760 4.65lbs and would be more expensive) however would offer a higher Ah runtime. I wonder if the DC9180 18v Lith Battery also adds more torque? This was my hang up when comparing the Makita BDF452HW which weights 3.5lbs but is nowhere near the quality but the price, torque, runtime, and weight considered in I believe the Makita is a better value…especially if it takes the DC9180 battery to give the DCD760 the runtime and torque to beat it out.
JC can you do a head to head with the Dewalt DCD760 using the DC9180 Battery vs the Makita BDF452HW? Your standard Torque and hole test. I think your test tells the real story. I really love the DCD760 the build quality and speed are second to none but the torque for my job banging out 2″ Holes in countertops is my typical use. The DCD760 is faster but I have not ran a hole saw test between the Makita BDF452HW. I would be curious to see how well the DCD760 would do with the DC9180 Battery. Let us know…thanks JC
Sorry, I am currently not doing any testing
Bummer!!! I was hoping to see this test…well if you ever do it throw in the Makita BDF452HW to see how it fairs. I bet the DeWalt would win in all…torque and runtime! Kinda sick of seeing the Makita get all the nods!
Heck forget about he Makita, I’d just like to see a comparison between the DC9180 battery vs DC9181 with the DCD760 to see what kind of difference it would make. May help decide what batteries to buy when the time comes for replacements seeing how the charger will do either one of them.
The DC9181 will give you about half the runtime of the DC9180
Question, I have seen in this forum again and again the Amp/hours of the DC9180 referred to as 2.2 but this page from support.dewalt.com says they are 2.4. The same as the DC9096. http://support.dewalt.com/app/answers/detail/a_id/1889/~/amp-hours-of-dewalt-batteries Who is correct?
Madtec might have a better explanation. The link you provided shows the DC9181 as a 1.1 ah, double that and you get 2.2ah for the DC9180. That’s why it makes sense to me.
Yes, the DC9180 is 2.2ah, that is simply a typo on the website, hope this clarifies it
wrong
DC9180 and in Europe DE9180 has 2,0Ah
greetings
mike
(by the way; I already have every 18V slide on tool that is available right now; very good impression !)
Yep, it surely is, because you can either get A123 or Sony cells in the DE9180.
per the new 18v line, which one is your favorite?
Thanks. This is good to know. I wonder how the 2.2 lasts longer than the 2.4 in the drill test? I was under the impression that more amp hours meant more run time. Perhaps it is because of the specific load that the drill puts on it? Maybe with a different tool that has a higher draw like the DC390 saw the results would be different? And thanks for the great site and great reviews.

The reason it’s 2,0Ah in EU and 2,2 in NA is because of regulations. Batteries are exact same inside. EU has stricter laws regarding advertising specs, that’s why 12v/20v MAX won’t fly there. From my memory of old european import rules for Bosch, the specs must show nominal values, not maximum values.
The battery is guaranteed to supply certain amount of power at capacity X, after this capacity is depleted the battery will still work but produce less power than the nominal value. So if you use the battery in a cordless circ saw you will mostly likely get 2Ah until the blade starts binding, but in a flashlight you will get 2.2Ah, regardless if it’s a UK or NA battery.
By specing it as 2,0 the company is protected from lawsuits for under-performance. I like this, I think such rules should be implemented in NA, so that the tools perform as advertised or better. Unfortunately here they perform ALMOST as advertised or worse. I also think the tool output power should be printed on the tool and officially regulated by PTI, ANSI or some other non-profit. Honest advertising is always good, false advertising hurt everyone. I’m looking at you, Milwaukee.
One battery might be 2.4 ah under very light load (flashlight) and only 1.8ah under very heavy load, while another might be 2.2 under light and 2.0 under heavy. Some manufacturers show these discharge curves.
Can some one explain 18 volt lithium and 18 volt lithium xrp they have the samepart number
As far as I know, the DC9181 is the compact 18v lithium ion (6 cells) the DC9180 is the XRP lithium Ion battery (12 cells) XRP- Xtended Runtime Performance.
I think he was inquiring the difference between the 18v “nano” and the 18v XRP having the same p/n, anyway, PM replied…..
