Yeah a 4/5 Ah battery on the impact drivers doesn't seem to make much difference unless you're driving big lag screws, and it really unbalances the tool. I always use 2Ah on my impact driver

a little over twice as long

I agree, thats only half of the test.I think they should have kept going until both were flat.

Yeah, the results could be interesting. However, as the differences will have the final dependency of what is the specifications of the motor max load and max toque. If the higher Amp with larger number of parallel cells configurations, (1P Vs 2P Vs 3P Vs ...) beyond the motor max load specifications, it will not going to give any difference ;-)

that is because the 3ah, 4ah, 5ah and the 6ah have 2 sets of 5 batteries in parallel so double the current and capacity. the 2ah has only 5 batteries in series.

@@jaakko200987654321 Interesting point. Thanks.

I find that true with my cordless tools (weed wacker and pole saw)

Check out vcgconstruction they have done this already

Same

@@mikeb1039 Amp hours do NOT necessarily mean power. The 6.0 will run twice as long as the 3.0 but the 6.0 will not have any more power than a 3.0 as long as they have the same configuration.

@@jps101574 watts equal power. Amps x volts equals watts. Unless it’s a very very low power demand the tool will draw sufficient power. Using too small a battery on a high load tool can damage the battery. I used to do testing on RC batteries so have quite a bit of experience with battery testing and data.

@@mikeb1039 I am an electrical engineer. I think I know the basics. I was asking for a test of power, not run time.

@@jps101574 how about a "starting current" for engines of cordless tools. When engine starts spinning, it needs more current for "stay in fixed voltage", 20v for example. Weak battery packs (1,5 2,0 3,0 Ah) not may get much more current at the starting moment. That's all difference! Bigger - better! P.S. but not for lbs😂

@@mikeb1039 Yes, in terms of run time. But power is a different story.

It's a property of the battery, so yes it will apply to any tool. If anything, it will be even more noticeable on a saw because it's a very high torque load

which brand ?

I opted for 6 Ah batteries for my Weed Wacker and my pole saw (a small chain saw on a pole for pruning trees). Both came with 1.5 Ah batteries, but due to the length of time on the weed wacker and the load on the pole saw I felt the higher Ah batteries were a good investment.

This sounds really interesting

@@Protoolreviews I always teach juniors that they are allowed to reverse drilling on only one thing. A screw, and nothing else.

It's in the name, 2ah means It can supply 1 Amp for 2 hours, 5ah 1 Amp for 5 hours

yes you can.. amp=runtime, it has nothing to do with power

@@erwinmaes3105 Amp = power output. Amp Hour (Ah) = runtime. A and Ah are NOT the same thing (like miles and miles-per-hour are different)

According to my understanding the Ah range stands only for the run time and could not harm the tool if you take higher Ah with the same voltage. But maybe I wrong......For one hand I don't want to harm the mower's engine but on the second hand i really want my mower to work more time.

Simple answer No it doesn't affect performance.the mower just runs longer

And the 2ah weigh a lot less than the 5ah, does that matter?

the 3 data points helps to prove the point. Agree a confounder is the fact that he bet the 5ah battery would outperform, therefore consciously or subconsciously he may be pushing harder with that tool. But again the multiple datapoints should help smooth that out. Also, they could have had the timer guy do the experiement too (who bet on a smaller difference). Would be intetesting to see what the difference in speed was with him at the helm. And yes going back and forth between batteries (and warmed up bits) would help. In fact warming up each battery and the bit to start (give each a trial run), then start to measure the time would help eliminate any differences due to 'warmth'. Overall though a neat experiment with an outcome that matches what is known to be true (5ah delivers more power/torque tha n 2ah)

Not true unfortunately

Over 6 runs for each test (24 total), by the same person, it will average out enough that it doesn't really matter: the difference is still stark

Same with ryobi hp vs regular 1.5 or 2 ah ryobi makes a hp 2.0 that comes with some tools but i havent seen it sold separately

It makes a huge difference. Especially with Milwaukee, just have to have the right version of the right size battery(High Output, Extended Capacity, High Demand, ect.) Dewalt is now in the game with power detect. But they all do it to some degree.

@@Protoolreviews 🙏thank you!!

Same with the impact wrench. Clear difference In power.

@@Protoolreviews and u my friend gets a sub

@@Protoolreviews so it is worth it to get a 3ah battery separately since I I usually drill steel

@@Protoolreviews I dont have the money for that and I dont think its available in my country

And how would shomthing like that be done? This is a great comparison, you're just nitpicking now

Like I said good test just interested for my own store of knowledge if higher ah = more power in physical terms not emotive terms...didnt mean to upset anyone

If I knew how the test could be done I wouldnt ask the question, I am a mere builder not a physicist tho we are all learning

It's not just the Ah, its the amount of cells in a battery. 10 cell (3-6Ah for Makita) batteries can deliver more current than 5cell batteries(1.3-2Ah for Makita)

@@aessu ryobi with a 4ah and craftsman with a 4ah

I was thinking the same thing. Also reflexes to stop start watch over time become more accurate but i appreciate the experiment!

Agreed. However the new 21700 cells in the new 3ah and 4ah batteries are changing that cut off a bit.

The 3ah has 2 rows of 5 cells, only the capacity is biggeron a 5ah, but maybe the cells are worn out a little and it's having some power loss because of that

@@lukie4ever Well, thanks for the reply, but I don't think they're worn out, as I didn't put heavy use to them...yet. I just have that DTW285 impact and a drill. If the impact is too tiny, well, I'll have to go bigger...(1001 or 1002).

@@wiedapp i have the makita ripoff from that dtw drill lmao

No, this test proves that larger batteries can supply more power to the tool.

Jose Vega Ampere-hour is effectively more runtime. But they got more Ampere-hour not by having better cells, but by putting the double amount of cells in parallel, which mean double available amperage too. Assuming the tool can draw this added power, you get a benefit, but not necessarily double the power as the tool can’t necessarily draw that much current. On bigger tools though, it can be even more of a difference.

No. Ah is a measure of energy storage capacity, not power delivery. Ah x nominal voltage = Wh, higher Wh translates to more total energy storage, and at a given power usage/delivery, that means longer runtime. But power usage/delivery is not fixed. There are two factors involved: 1. Amount of power the cells can supply, sustained and instantaneous. This number typically varies with both Ah (2.0, 2.5, 3.0, etc) rating of the cell, and size of the cell (18650, 21700, etc). Since power is voltage x amperage (aka Watts), and all these batteries are nominally the same voltage, it all depends on how much amperage the cells can sustain. 2. The number of “packs” or “banks” of cells in parallel. An 18V (20V max) LiIon battery in a 1P (single bank of cells) contains 5x 3.6/3.7V cells in series. But those cells (18650) top out at 2.5Ah in they types used for “traditional” (not HP/HO) power tool batteries, because the 3.0Ah and higher versions have lower current/power delivery ratings. So to get above 2.5Ah, you have to either go to a 2P (2 banks of 5 cells in parallel, 10 total cells) or even 3P configurations. Thus, a traditional 3Ah/4Ah/5Ah battery is a 2P configuration with 10 cells. That means it can potentially deliver twice the amperage/power, if the tool can use that much. But since the tool will rarely need/use that much. It also means longer runtime. How much power or speed, will depend upon the specific tool and how hard it’s being loaded. For lighter loads, you might simply get 2x the runtime, but for heavy loads, you might get faster results, and 1.5x-2.0x the runtime. The newer High-Output/High-Performance batteries typically use 21700 cells, these are larger, and can deliver about 50% more current than the 18650 cells used in traditional power tool batteries. They’re also available in capacities up to 4.0Ah, so a 3.0 or 4.0 HO/HP battery can be a “compact” 1P configuration using just 5 cells, while the 2P configurations will be 6.0 or 8.0 Ah, and 3P configurations will be 9.0 or 12.0Ah, capable of delivering very high amperage and power, and/or longer runtimes.

Mean O’ Dustino I have the 2767 and have only used it with a XC 5.9 so far haha

Not true

@@scampbell6008 not unless the voltage has changed. It's in your head.

@@scampbell6008 if I'm wrong, ohms law and watts law is wrong.

grumpybill your very wrong . Going from my 12v 2ah to my 6ah gives a notable power boost on my impact , my 18v 5ah to my 9Ah on my sds drill exactly the same . Voltage isn’t everything my friend . This video shows that and the voltage x amps gives you watts so doubling the amps increases the watts . Some people will never believe it but it’s true

@@robswingler doubled Ah, not amps.

@@scampbell6008 didn't watch video. Edit: Just watched, my comments stand. Ohms law and watts law explains this.
