A LOOK INSIDE MAKITA'S BL1815 18V 1.5 Ah COMPACT Li-Ion BATTERY.

HERE ARE A FEW SIMPLE STEPS ON HOW TO PROPERLY REMOVE THE ROHM SUPRA SK CHUCK. THESE STEPS SHOULD WORK FOR MOST DEWALT HAMMERDRILL MODELS. http://www.youtube.com/watch?v=UEj8qv02o9Q#noexternalembed#

Welcome to the Forum Stanon1. That's a nice collection of Dewalt tools! I am going to assume that Dewalt is already month's into a new design for a radio. The charger/radio is a Dewalt patent, and a huge + for that reason! I would assume any new radio in the works would include a XRP Lithium Ion charger capability. Not if, but when they do release a new radio I also hope it is I pod compatible. My ultimate radio would include great features from all radios. It would have to have good sound like the Milwaukee, GFCI's like the Bosch, and a built in I pod carrier like the Ridgid, and a sleek design much like the Makita white radio. The charger is a must, and it's got to be weather resistant, with a very durable drop shell!

Last week I had to cut through several old 4" galvanized pipes, by the time I was done it was noticeably warmer under boot. That's where a lot of the friction happens, which is why it's important to properly maintain that area with lube.

My take on battery technology is this... A cordless tool does not know what chemistry is locked to its lower half. NiCd, NiMH, or Li-Ion. Juice is juice! Ah and tool efficiency really play a big part when it comes to runtime. Chemistry plays a larger role in battery life. I find all this battery marketing to be very mis-leading to the general public. Some tool companies boast huge runtime gains with their Li-Ion batteries, which leads people to believe that lithium has more power, and runs longer. Those big numbers come from a comparison between old NiCd and NiMH batteries which not always but typically had less Ah. For example, if I took Makita's 1822 NiCd 2.0Ah battery, and compared it to their new BL1830 3.0 Ah Li-Ion battery. I could say their new Bl1830 Li-Ion has a 30% longer runtime. This may be true based on Ah alone. However they never mention that. They just let you assume that Li-Ion all on its own = longer runtime. In theory a NiCd battery with the same Ah and voltage as a Li-Ion battery, should equally produce the same amount of power and runtime. As far as more power goes, the power to weight ratio has changed. Some tool companies have said that Li-Ion delivers more power, sure... maybe power to weight over previous NiCd models? As far as testing the Dewalt against the Dewalt? The new Dewalt DC9180 XRP Lithium Ion battery will outperform the Dewalt DC9099 compact NiCd battery used in this test. This is because the DC9180 has 2.2Ah, while the DC9099 only has 1.7Ah. For maximum runtime, the DC9096 XRP NiCd battery is still your top choice as far as runtime is concerned. This is because the DC9096 has 2.4Ah. To answer your question on the Milwaukee. I'm sure electronics played a huge part in the battery shutting down. Large draws like that are not good for any battery. However that was the whole point of this test. Every one of these compact drills are fully capable of drilling 3/8 holes, and driving screws all day long. That's hardly interesting. We decided to push these compacts harder to see whose drill can perform under heavy draws. This kind of test shows the drill's durability, and efficiency. Whichever drill can deliver the most holes under heavy draws is clearly going to do more work per charge in all other tasks.

THIS IS PART III OF A SERIES OF TESTS BETWEEN THE DEWALT DC720 vs OTHER COMPACT DRILL IN IT'S CLASS. THIS IS A TEST BETWEEN THE NEW MILWAUKEE COMPACT 2601-20 vs THE DEWALT COMPACT DC720KA! CLICK ON THE FOLLOWING- PART I PART II IF YOU HAVE NOT READ THEM YET. THIS TEST WILL COMPARE INTERNAL SPECS, DEMO TESTING, WEIGHT, FEATURES AND BENEFITS! WEIGHT: INTERNAL SPECS: FEATURES AND BENEFITS: ONTO THE TEST: In this test, we used a piece of 2x12 fir. We also used a 1" spade bit. The test was conducted to see how many holes could be drilled on a single charge, in 2nd gear. We wanted to push these little compacts to see how efficient they use energy under heavy draws. The Milwaukee compact was packed with features, but did not perform well during our test. We got about 5 holes per charge. It might be understandable if one battery in the kit was bad, but we got consistent performance from both batteries. The Dewalt DC720ka beat our previous two tests and drilled 37 1/2 holes. The Milwaukee 2601-20 did 5 holes per charge. DEWALT DC720 Drilled 37 1/2 Holes, or 22 holes per ah. Milwakee 2601-20 Drilled 5 Holes, or 3 holes per ah. For more detailed photo's on both drills...

HOW TO GREASE THE GEAR ASSEMBLY ON THE DEWALT DC385K RECIPROCATING SAW. STEP 1: PUSH PIN AND REMOVE SHOE. STEP 2: REMOVE BOTH BRACKET SCREWS. THEN FIRMLY GRAB THE RUBBER BOOT AND SLIDE OFF. STEP 3: REMOVE BOTH PLASTIC COVERS. STEP 4: WITH A GREASE GUN, SQUEEZE IN THE RECOMMENDED AMOUNT OF THE MANUFACTURE’S SPECIFIED GREESE. IF YOUR DEWALT DC385K RECIPROCATING SAW HAS NOT BEEN PROPERLY MAINTAINED, IT MAY BE A GOOD IDEA TO REMOVE THE GREESE CASE COVER & CLEAN ALL PARTS AND BEARING, INSPECT AND REPLACE THE GASKET IF NEEDED.

The battery that is included in the kit. The DCD970 is XRP lithium Ion with a silver clutch. The DCD950 is XRP NiCad with a black clutch.

The DC927 is newer, but was designed to be lighter, with better ergonomics. It was probably produced with the Lithium band wagon in mind. I've done test's between the two and the DC927 does perform as well as the DC925. I'm glad to see the DC970 take it's place. I did a comparison between the DC925 and the DCD950. The comparison was done with the lithium batteries, so it's an identical test seeing how the only real difference between the DCD950 and the DCD970 is the battery.

In terms of power... The DCD950 "felt" like it had more power. Dewalt rates the DCD950 at 450 UWO, and depending on the literature, the DC925 has 480-510 UWO. So on paper the DC925 should complete applications faster than the DCD950 based on the theory of UWO. But in this test, that was not the case. I did not time each hole drilled.

Here are a few shots inside the DC827/DC825!

Anyone feel free to correct me if I am wrong here.... The Dewalt DC9180 Nano-Phosphate Lithium Ion batteries have never changed. However maketing has. The first battery was the first "nano" Lion you saw on the market. I don't think the general public understood what "nano" meant. The second battery bears the Lithium Ion logo on it. The third and most current shows the Lithium ion in bright yellow, below the 18volt image is the XRP image. On the back it shows XRP lithium ion. As far as I know, the chemistry has not changed. Just the marketing. All three of my batteries shown have the same A123 APR18650M1 cells in them.

I'm not quite sure, probably similar to the DC720, only with the Hamerdrill feature. It's the same as the DC725, only the DCD770 is lithium. The UK also has a similair version DC727 only not as much UWO.

It's a very noticable difference. It's almost too stiff. Probably one of those things that will wear over time.

I believe any Dewalt 3 speed transmission that shifts left to right has a shifting issue. However I'm not even sure I want to call it an issue. There are times when you must baby the trigger slightly to engage the transmission in order to shift to the next gear. I believe this wears in better over time. The DC927 weighs the same as the new DCD950. However the balance is greatly improved. The "issue" related to shifting is gone.

They are the same batteries, just a new marketing strategy. In fact this is the third cosmetic change in the last 12 months on this battery. I understand that dewalt is doing away with the Nano campaign. It will now just be cal XRP-Lithium Ion. I did this test with the lithium battery, but this drill (DCD950) will still come packaged with the XRP battery.

The DCD950 will now be replacing the DC925. So we decided to do a few comparisons, and a small test. From top to bottom DEWALT has changed the DCD950 in almost every way. It is much smaller, only 9 1/2" front to back vs 10 3/4" on the DC925. Height is about the same at 7 7/8". DEWALT has added a bright switch LED light similar to the DC827. The grip handle is slightly smaller, and has an inset, two piece rubber grip that extends the full length of the handle. With the DCD950 shorter in length, and improved ergonomics. The DC950 has a better feel and balance than the DC925. During our test the DC925 was front heavy and could not stand vertical with a 2 9/16" self feed bit in the chuck. The DCD950 did not share the same problem. However both were tested with Lithium Ion batteries which have a much smaller base than the traditional XRP batteries. DEWALT has also changed the look of the new DC9180 Batteries. DEWALT has added a dual clutch collar so you no longer need to change your clutch settings during drilling and driving mode. The DCD950 clutch ring felt a little tight to turn but had a much stronger feel than the DC925. DEWALT has also improved there Patented all metal 3 speed transmission from left to right shifting, to a front to back style. Inside, the DCD950 transmission gear case is made of metal which DEWALT claims will help dissipate heat. The front to back transmission configuration has steel pins that positively lock each gear in place which is a huge improvement over the DC925. We found The DC925 could easily slip between gears during shifting modes, and sometimes would not lock in gear until the trigger was slightly pulled. The transmission speeds have also been changed. DC925- 1st 0-450, 2nd 0-1500, 3rd 0-2000. DCD950- 1st 0-500, 2nd 0-1250, 3rd 0-2000. During our test the DCD950 in 1st gear drilled a 2 9/16" self feed bit much faster than the DC925. Using a 1" ship auger bit in second gear bogged down the DC925, but the DC950 had no problem. So this new configuration seems to have improved performance. The DC925 has 480 UWO while the DCD950 only has 450 UWO. Even though DEWALT claims the DC925 has more UWO we felt that the DCD950 out-performed the DC925 in everyway. Another change DEWALT has made is the patent pending, flat magnet frameless motor. DEWALT claims this improves motor efficiency and allows for better heat control during use. About the only thing DEWALT decided to keep the same was the self tightening chuck which is only found on the hammer drill models. We really liked this chuck with only one down fall. During heavy applications the chuck can become so tight it can be hard to unlock. However we never once had a problem with bit slippage during our tests. ON TO THE TEST DEWALT Claims that the DC950 has 30% longer runtime than the DC925 model, so we decided to put it to the test. After running 3 different tests with a 2 9/16 self feed bit, our average runtime increase was about 33%. On average the DCD950 drilled 40 holes, while the DC925 averaged only 30. All tests were done with the Nano Phosphate Lithium Ion batteries. Overall the DCD950 stacks up to it's claims! DEWALT has really built a solid drill, there were a few issues with the previous model DC925, but it seems all of those issues have been met. I will be adding to this review with comparisons from other brands to see how they compare up with the DCD950. --------------------------------------------------------------------------------------------------------------------------- added Feb, 2nd 2009 CLICK HERE FOR THE FOLLOW UP COMPARING OTHER DRILLS!
