Right after we pitted the Craftsman CMCD721 hammer drill (2Ah battery) against the Ryobi P251 Hammer Drill we got some feedback regarding those batteries. We used the packs that came with the kits—but that meant the Ryobi had an apparent advantage with a 4Ah pack against the Craftsman’s 2Ah battery.
That’s not a bad point—and one we felt the need to tackle in another Thursday throwdown using the Makita XFD07 drill as our reference. The results tell a very interesting story!

Youre pressure on the drill may varry

I have both 1.5 Ah batteries and 6 Ah batteries. I can tell there is definitely more power available in the 6 Ah battery.
I personally think it depends on the project. To drill just a few holes or drive a few basic deck screws, I think the lighter weight of the smaller battery is worth a few extra seconds of my time. When it comes for heavier duty work, such as larger spade bits, bigger screws/lags,or extended periods, I’d go with the larger size batteries for runtime, and extra power, depending on application
Does a 40V 2.0AH battery weigh significantly less than a 40V 4.0AH battery?
find my Greenworks weed wacker to be quite heavy with a 4 attached and wondered if switching to a 2 would do anything for me.
Should have used a hammer drill
It would help to put the Drill in Reverse when removing it out after drilling through
Lol he understands what the viewers want lol we don’t need all that damn chitchat 😂
Thanks guys for taking the time to do this test. You answered my question. Like and subscribe button punched.
Feels like there's some undercover tension between these guys on the banter 😂
Can't help but wonder how 2AH vs 5 AH batteries effect no-load rpms – measured with some kind of accurate tachometer or strobe. Also wonder if torque can be measured. Some more controlled, repeatable, scientific tests without the variability or subjectivity of humans and without pushing a tool beyond reasonable, normal use. Test the batteries against rated specs. If you need better performance, why not get a better (heavier duty) model tool?
Would there be any difference in battery life between the 2AH and the 5AH?
You have one job😁
I had this question in my head for a while cool video fellas
6:48 😂😂😂
There's too much room for human error here for this to be at all accurate. You should've filmed it with a 60FPS camera and then worked out the time by counting the frames. Could've done that with your phone – probably several hundred FPS. Also, getting a human to randomly drill holes is obviously an issue. You could've used a torque meter to do a very easy and reliable test.
Can u put time index for all tests ty
If the cells are the same in the batteries a 2.5 ah vs 5 ah will only provide a longer runtime. Although this test looks fun it's accuracy isn't great. If the pressure on the drill is different the results will be different. The fact it's 2ah vs 5ah will have different results as they probably use different batteries and or you have less batteries in series..
I find the 3,0 amp battery to produce much less dust than the 5,0 amp one… BUT…. You can see much more easily through the holes drilled with the 5,0amp battery which makes this quite a difficult choice. I also noticed the 3,0 amp battery to be somewhat noisier. Now I'm at a complete loss as to what should I go for. Thank you guys for confusing me even more!
Thank you for the video and the excellent explanation at the end of the video. Looks like higher Ah batteries not only produce more torque and cuts down the work effort and time it also will last longer since it is less stressed. Thank you again.
I would like to mention is it worth getting the 5.2A over the 4 and 3 A packs for chainsaw use? as there is huge price difference for the 5.2A Packs. Run time would be important to me here.
There’s a little problem with the correctness of your experiment. Your manual pressure applied on the drill could vary between between tests. You could be pushing harder on one test or lighter. Not very scientific 🙂
Очень интересно 👍
This isn't really an accurate test unless they hook the drill up to a machine that can provide consistent pressure. The inconsistencies in the OSB could also have higher resistance in some areas
My generator battery is 12v 15ah 20hr can I sub it for a 12v 18ah 20hr? Does it matter?
Thank you very much great test ..Conclusion that higher power equipment needs higher ampere batteries
I have dewalt 5.0ah for my jigsaw and reciprocating saw. Smaller 1.5ah (I think? for my drill and small jobs for the impact)
I also have a hitachi (I guess now metabo) drill that I replaced the 1.5's with 3.0. I'm really enjoying the Metabo. The feel, performance, etc. Looking at purchasing the Metabo impact (18V) wondering if tbe 3.0 would suffice for homeowner purposes or upgrade to their massive 6.0? I kinda think that huge 6.0 would add a lot of weight and would be more suitable for things like cordless circ saws, mitres,.
etc, opinion?
That guy is genius. I couldn’t get a coherent explanation that made sense to me until I watched this video. Thank you 🙏.
Ok so between a bosch 18V 1.5ah and 18v 2.0ah
Is there any significant difference in life
And how long it lasts on charge
Like as in 1 hr on 1.5 and 2hrs on the 2.0
I drill knife steel mostly
If you focus on his thumb for the stop watch. He’s slow to react to the actual driver start.
Just getting into makita. I got 4 each 5 aH batteries that came with my kits and a 1 2AH battery.
Great Comparison. Exactly what I needed to make a decision on a purchase.
idiots with no clue.
When you pull the drill out of the hole, do you reverse the drill anti-clockwise?
I think you don’t, but not entirely sure.
If you reverse it, then I would like to say that drill reversing while coming out is taboo in my line of work as an orthopaedic surgeon for past 42 years, drilling and reaming tens of thousands of bones.
We keep turning clockwise while coming out. Always.
The reason is that reversing a drill will damage the drill bit.
Damn the optimism is out of the roof 😂
@Pro Tool Reviews Im looking for new batteries for my Makita products i have drills only at the moment but looking to expand to router, sander, circular saw? As power band & charge time goes 3Ah has served me well. But im concerned other tools will demand more power what do you recomend from 4, 5, or 6Ah for comfortable use time & charge rate used in high drain tools? Ive also seen aftermarket 2.5Ah on the slim profile batteries on ebay which could be useful in a tight spot but dont trust the Ah advertised by the c*****e sellers and the reviews make no sense look copied & pasted. At worst they could be guttless 1.3Ah? For all we know not whats stamped on the tin. Is there a way of testing Ah by loging charge time any info much appreciated to tell me how best to purchase the tools with or without bats for price?
I was always told no matter the amps, when volts were the same, the battery would produce the same power output and the amps only determined run time.
Would there be that much of a difference between a 1.5 and 2 ah battery that would be worth the extra 60 dollars?
Thanks for that. Solved a discussion we were having. Nice video too.
In fact, this gain is not due to the greater number of energy cells, but to the type of energy cell used in each battery. The 2Ah battery uses 5 Samsung 2000mAh power cells with a maximum CDR of 15A. The 5Ah battery uses 10 Samsung 2500mAh power cells with a maximum CDR of 20A.
thanks ,i did not realize you can interchange battery amp for same tool
Thank you for this review. I only have the 2ah on my subcompacts, but know if I need more umph, to swap to the 5ah. Also just read your 6ah review and I am about to grab the last pair in the area while they are on sale.
4/5Ah when doing hard work, 2Ah when in the back of a cabinet or the bigger batteries are all on charge… works about as well as I need it to, and means I don't need to pay for half a dozen big batteries
I'd also expect the difference to increase as the charge drops – on my electric car there's a noticeable drop in power when at 20% battery vs 100%
I am wondering how the Dewalt 12 Ah vs. 5/6 Ah will perform and do with a saber saw, sander, oscillating saw?
Not accurate. Because if you push hard on one example and less hard on the other you will have different result.
Ah=runtime.. Nm=power
Are all the battery sizes in the same line interchangeable? I thought they were but I grabbed a 5ah to use on my drill that originally came with a ?1.5ah and it didn't want to go on. ?
Can I put 5a on a makita brushless?
It came with 2am but it’s also 18v
If straight from the capacity point of view, 5A does not have advantage against the 2A..
However, after the explanation of how the 5A being configured as 2 rolls of parallel cells, then is a totally different condition. Because of 2 parallel configuration, it allow a higher outflow current loads.
Like some of is familiar with Lithium ion battery with the "C" rating, higher "C" value will allow a higher level of current (Amp) flows through.
As higher demand tasks, having higher resistance, and required higher torque power to accomplish the task, thus as a result higher load to the motor, and result in draining higher current from the batteries.. all these means, needs higher current flowing out from the batteries to the motor.
😉
Good test but I would like to see something more accurate without the variables of arm hand and finger fatigue, micro differences in the pressure applied by the user etc
