- Does a five amp hour battery have a power advantage over a two amp hour battery? Watch this video to find out.
This video is only about Dewalt batteries, other brands may be different.
Dear tool review guy...This review would have been much more useful in the differences of those 3 batteries if you simply chose a tool, and used it to perform an equal task until battery depletion (and timed it) using each battery. Now, do battery amp hours affect power? Yes and maybe, because that depends on the pack design as each cell in the series has to contribute the full current since it isn’t additive between series connections. If the 5 cells in the DeWalt 2.0Ah pack each need to deliver say 20 amps, and in the 5Ah battery there are two sets of 5 cells (10cells), the parallel connection between them does make the current additive. So each set only asks its cells to give 10 amps each.
It’s much easier for 10 cells each working half as hard to keep the power level up. The tougher the task, the harder it is for 5 cells to maintain the same power level as 10 cells would. In lighter-duty tasks, a bigger battery doesn’t have a huge advantage, so save some weight and go with the smaller pack. As you move into medium and heavy-duty applications, the difference is noticeable and a higher capacity battery is the way to go. Remember, the amp-hour rating of a battery (also known as “AH”) is a measure of how many amps a battery can supply for a period of time...It is calculated using the formula Amps X Hours. For instance (in an ideal world) this rating would mean that if you have a 5AH 20 Volt battery, you should be able to supply 5AH Amps from it for 1 hour, or 2.5 Amps for 2 hours, or 1.25 Amps for 4 hours, etc. That would have been a much more valuable test my friend...Cheers
Mate, I've been watching Dewalt reviews for 2 days. This is the best I've seen. Cheers from Oz.
Brendan King thank you
All the best IN THE TRADE we need more of YOU !!! excellent review
Thank you! I’m glad you liked my video!
I've just recently came up to speed on battery Ah in the last 2 years because my boss is a Milwaukee fanatic and I realized how many different batteries he had in the warehouse. It got me pondering is DeWalt had this many different choices also. My drills always came with 1.5Ah batteries and I had two 4Ah batteries already and have never needed more juice for my work load. Making sure to keep my batteries charged probably had a lot to do with that also. But I guess it's time to find a 6h-12Ah battery for back up purposes, but they're just so darn expensive. Time to hit the pawn shops lol
Nice review and great info. Thanks!
Just an opinion from a guy that uses this stuff every day. Switched to the twenty volt about four years ago and bought four of the 5a batteries as well as a couple of 2a that came with the 20-18 v conversion adapters. Using mostly drivers and drills and occasionally circular saw, sawzall and grinder and not biasing towards the 5a (using whatever was charged), three of the four 5a quit taking a charge and could not be jumped back to life over a year ago. The last of those four just died a couple days ago. I have two 2a and 1.5a that are all within six months in age of the 5a’s, and they’re still going strong and have jumped back to life whenever discharged past charger detection. Personally never noticed any difference in running time other than being surprised that 5a didn’t seem to have any negligible difference from the 2a. Just bought two more 2a for $79 rather than the 5a two pack for $199 because, as I opened with, “in my opinion” the 2a get the job done for my purposes; ie a lot of drill/driver use and occasional miscellaneous cordless tools (saw, sawzall, grinder), and from experience the bigger batteries are cumbersome and didn’t last like the 2a which satisfies my needs. I know a lot of guys that are in love with cordless tools, and I use them too, but nothing cuts, sands, grinds, etc,... like a corded tool for jobs where the trigger is being pulled for more than 30seconds to a minute. There’s a lot of these comparison videos out there but Just saying my experience is I won’t waste the money on anything other than the 2a and 1.5a that come with the tools anymore.
Agreed👍 I’ll always be keeping the 2ah and 1.5ah batteries around for drills and drivers as well as the palm sander. When I’m doing a big job (like sanding for an hour straight or hacking through a bunch of concrete fence posts) I always prefer to be plugged into the power supply rather than relying on a battery. Of corse when there’s one cut you need to make it’s always handy just to pull out the cordless saw.
I like having both an impact driver and a drill as they aren’t really the same tool. If you’re only going to have one, I would suggest 18v as it has more power and can do the bigger jobs that a 12v can’t do.
I’m currently using all 20v dewalt batteries for cordless tools. Drill, impact and 4” grinder are 20v tools. Saw all, hammer drill, and circular saw are 18v with 20v battery adapters. Not happy with the chuck on the 20b drill but it wasn’t the best one they had. All 2a and 1.5a 20v batteries. Hope that helped.
For cabinets I’d think you’re going to want both tools. Can usually find a good two pack deal for 99$
What about the 12v 3ah batteries? I'm finding the 3ah batteries are the best prices, sold as new on Ebay. Typically only a few dollars more than the 2ah.
For me one of the most informative videos on this particular subject, thanks
Thank you for watching
Ah is more about run time! A bigger battery "can" provide a bit more oomph during high stress as it has a larger pool of energy,however the cells in the packs can only provide so much current before the protection kicks in and the motor can only draw so much current before it's overheat or overcurrent protection kicks it.
This is assuming DeWalt is using the same cells for all the packs,and in the larger packs just adding more cells for capacity.
however in the larger packs DeWalt could be using cells that can deliver more amps,but you'd still be limited by the upper end of the tools motor.so I doubt that's really the case.
So overall every pack will provide a minimum,and every pack has a limit that is within +/-5-10% of one another.
thanks for the review, it shows you can get any of the basic work done (for non experts) with any of these batteries. I found your review because I just got the dewalt 20V car tire inflator - it works well, but I noticed the 2amp battery drains fairly quickly whereas the 5amp seems to last longer which makes sense as it has more power to deliver. Its good to know what you can expect from each different battery. For regular household stuff I like the 2amp battery because its lighter.
Yes, for small tools any battery is fine however on things like circular saws and grinders the five is definitely worth it. The 5ah is my favorite because it gives the tools good power and the best balance in your hand. Thanks for watching!
Good review, keep up the good work
What was the brand of that auger bit you used?
Ap A thank you. The auger bit is a brico depot special, can’t remember the brad.
Good review....thanks T.B.
Very good review, enjoyed it.
Thank you.
Great video! Thanks!
This video was inspiring. It makes me feel like i could do these videos
Ironic, you had the die grinder I just got. Too used to having cords, and finally can't reach them as easily. Good to know, I was wondering about the weight/fatigue of the battery weight, but if 5 is the way it should be, then like the Mandalorian, "This is the way" lol.
By far THE best review comparing these dewalt batteries on TH-cam....Thanx...and keep it up...I'll watch for more....Danny
Thank you.
Thanks, I like your reviews. Is there any difference in the battery dimensions 1.5ah vs 2.0ah?
1.5 ah and 2ah are identical sizes except 2ah batteries have a fuel gage and 1.5 doesn’t. Thank you for watching!
I got 1.5ah batts on my ridgid drill/impact combo and this websitr called direct tools outlet sells Ryobi and ridgid pre owned and factory blemished.. Anyways got a 3.0ah octane for $35 and they had the 4.0ah for $29.99 ($40) shipped which is a deal for actual ridgid brand not knockoffs. Been curious about higher AH batteries.. My 1.5s dont last that long.. I have been mainly using them with usb adapter for my electronics when not usin my tools and i can tell the 3.0 octane lasts quite longer.
Thanks for the review, i am new to the above 1.5ah club haha. My other 2 brand tools (bauer drill and cheap hypertough walmart sawzall are 1.5)
Edit: i dont get all the dislikes, u did good. Then again someone has to bitch about something. I did a video on my hypertough recip saw and a few people were talking shit.. O well, that's the internet for ya.
Thank you for watching! Are they pre-used batteries or factory blemished batteries that that company sells?
Great video and very helpful, any recommendations which battery I should go for my dewalt tire inflator? And should I get 2 or just buy 1 is enough? I don’t have any other deawalt power tools anyway ? Thanks
I would imagine a 2ah would have the power to run it but a 5ah would definitely have more runtime. I always like having at least two batteries because then if one runs out while I’m using the tool I don’t have to sit around waiting for it to charge. Thank you for watching.
@@toolreviewsandrestorations make sense 👍🏼
I don't see what the 6 dislikes is all about this was actually a helpful review,i actually has been using that same jigsaw which i find is ok with the 5AH battery because it has a nice balance to the tool overall & yes you are correct the sander is clunky & gets heavy after a while with the 5AH also the new dewalt cordless router after a few use your hand actually starts to fatigue and tires,so i am actually gonna invest in the dewalt compact 3.0AH batteries just for the use of that router and sander for hard to reach or off the grid projects,i actually used the flexvolt batteries on these tools yes again u get more runtime but it is all about comfort by the end of the day,thank you again for your review brother.
Nature King thank you. The five is my favorite battery of all although I prefer the two on my impact driver and sander.
Your review was very helpful. I now know I don’t need to get a 5 amp hour battery right away. My circular saw and reciprocating saw do well on my 2 amp hour batteries, but run time isn’t really important as I have 4 of them. Also my angle grinder works well on the 2 amps. 👋🏼👋🏼
The 4 amph batteries are good not to heavy i noticed a difference in power in my drill could just be me thk
Nice job!
Great video
Looking at the drill driver dcd777 the max rpm is 1750. Does a 1.5 ah battery reach the full rpm of 1750 and in saying that is it necessary to buy a 5ah battery that may exceed the max rpm on the dcd777 drill? In other words is the 5ah battery more suitable for a higher rpm tool say like a hammer drill? I have a dcd777 drill I use it on a 6 inch nils ice auger using a 1.5 ah battery and it will cut out cutting through a 8 inch hole through the ice and then it will start again. Should I buy a 5 ah battery and will it cut through a 8 inch ice thickness before stopping during cutting?
I don’t really notice a power or speed difference on the dcd777 between batteries unless I’m using it for a really big job that draws a lot of power.
The issue you are suffering from may be the tool is lacking the tourque required for the task so may be a new drill is in order however a higher capacity battery has multiple layers of cells to distribute the load so instead of a single layer capable of 20a max
You could have 2 layers capable of 30amp max to give a rough idea as each battery is different
Thank you
Hi I’m from England I find my combi drill and impact work best one 2 amp batteries in my opinion they make the tool lighter and thinner when on ur belt it’s just a preference of mine to use 2 amp batteries however mine came with 3 amp batteries I still use the 2 amp for my reasons of being lighter and the right power for what I do however my circular saw needs a 6 amp so I’ve got one on order great video nonetheless you sounded nervous at first but you did amazing
Thank you! I’m glad you liked it! I like to use the 2ah batteries on my drill and impact too. They are balanced in my hand that way.
@@toolreviewsandrestorations yep I feel like then2 amp are the right ones for the impact driver it’s not a lot of power so you do strip the screws which is very annoying when it happens and with them being quite small you can fit quite a few on ur body or in your tool bag for spares
Nice video, appreciated
Thanks
Awesome! Thanks 👍
Hi there, quite a collection you have . I am looking to buy very soon a dewalt barrel jigsaw, I was looking at the 2ah X 2 or 1 of 4ah. It occurred to me that if i used up the power from the 4ah and did not have a backup I would be screwed doing some ones job, but If I have 2 X 2ah then so long the spare is charged i am good to carry on plus then I charge the one I just used up . What do you think? ps do you find the barrel grip version better, even though the on/off switch, speed control is a bit iffy of their location??
Thank you for watching! I like the barrel grip jigsaw very much and I have a review on it if you want to see more of it. The jigsaw works fine with the 2ah batteries as long as you aren't cutting very think stuff. I haven't used mine with the 2ah lately but it worked well when I did. The jigsaw is pretty good at giving the same power even if the battery isn't full or you have a smaller battery on it.
@@toolreviewsandrestorations yes, the most I would cut is around 24mm (birch ply) . Have you your link to the barrel grip video?
Here’s the review for it: m.th-cam.com/video/dOzofXWRhJQ/w-d-xo.html
A simpler test would been to drill into brick or solid concrete with each battery.
I instantly learned the difference between a 1.5 ah battery and a 4 ah battery when I was drilling holes into bathroom tile.
I did not have a cordless hammer drill yet when I filmed this video but yes, concrete is a great test for comparing tools or batteries. Thank you for watching
How much voltage/volt is on the impact driver?..just curious.
It’s an 18v (20v max) impact driver. Thank you for watching
hi...can you tell us how long it takes every type of battery? time
Thanks for watching. The 1.5ah lasts 15 minutes, the 2ah 20 minutes, 4ah 40 minutes and the 5ah 50 minutes. But that's only on the palm sander.
thanks wade
Nice vid thanks
Glad you liked it!
Now about the 1.5ah and 2.0ah
Is there any significant difference of battery life one charge between a bosch 1.5ah battery and 2.0ah battery
Thanks for watching. I don’t have any experience with Bosch li-ion batteries but if it’s like Dewalt, there should not be that much of a difference in battery life between the 1.5 and 2 ah
@@toolreviewsandrestorations so I saw some other video before urs that compared a 2.Ah and 5.Ah
And there wasnt much difference in anything so I guess it doesn't matter and is just a partial selling gimmick
Yes, although you will notice the difference between a 2ah and 5ah on bigger tools and you’ll also notice a difference in runtime
@@toolreviewsandrestorations ah ok so I guess I'll go with the 2.0 ah battery and but a 3.0ah battery separately since it's the similar price for a 1.5ah and 2.0ah battery in my country
but how many Ah does that driver in your video run on? and what model is that driver?
bluekeet I’m not sure what the amp rating is on it but it will run on any Dewalt 18v xr or 20v max battery. It’s the dcf887
How long would the 2ah and the 5ah battery last on the driver....looking at buying an impact driver and I feel that 2 2ah batteries will do me but I'm not sure if they will run for long
The 2ah lasts a long time on the driver and it is more comfortable with the 2ah on it than the bigger batteries. I haven’t done a runtime test with the impact but I can drive a lot of screws with it before I have to change the battery.
XR basically means Extreme Runtime. I think the 1.5 ah is also included in this category. The battery ah literally effects the runtime not the power output. You should have seen how long they ran the same spotlight continuously. This would have been a better suited test.
Can any1 explain what the run time is like on the 2ah 4ah and 5ah
It depends on what tool you have it on. On the palm sander it’s about 10 minutes per AH.
So not just longer run time but more output??
Charles Wolford it depends on the brand. On the Dewalt yes. Although I don’t think there’s a power difference between th 4ah xr and 5ah xr batteries. Thanks for watching.
Hey, i bought the dewalt combi set which was my first out of the xr range, they came with the 1.5ah batteries, and i think i bought a few 3ah batteries as add on's, and the 3ah doesn't seem to provide the tools with anymore power than the 3ah at the trigger, but they last longer between charges
Im probably going to sell the 1.5 ah batteries and save up for bigger batteries, and if i buy anymore xr range dewalt tools, ill buy the "bare" units that come with no batteries or chargers, then ill jist use the batteries that i have, which i have done with the oscillating multi-tool last week, i bought that bare and used the 3ah batteries with that 👍
Thank you for watching! Sounds good 👍. I personally wouldn’t sell my 1.5s but that’s just me.
@@toolreviewsandrestorations after commenting, i suddenly remembered why i kept the 1.5's in the first place, i used to build deckings, and it was sometimes a real pain to get the drill or the impact driver into gaps with the bigger batteries, i use the 50mm long impact bits, and sometimes i had to use a shorter bit just to be able to get into somewhere, then the front of the battery would foul, so yes, thats why i kept the smaller batteries 👍😁
It’s one of the reasons I have the smaller batteries too
Greetings. How did DeWALT batteries perform after a long time?
I’ve been using them over eight years now, they’re pretty good
Is the 1.5 and 2.0 battery the same size?
Yes, they are physically the same size
2ah battery on dcf899 will it work
Yes, it will work.
If I replace a 1.5amp battery with a 6amp battery will it damage the tool?
As long as it’s the same brand it should be fine
You won't notice a difference from 4amp to 5amp but move up to the 6amp and you definitely notice
great items at a great price
nice bro
Thanks.
It is the same power of 1.5,2,5 the difference between one battery and another is only the endurance of the battery life at the time of working with full charge
Thank you for watching!
Thanks for being honest bro. I do think with bigger battery packs the power maintains itself where as with the smaller packs there's a drop off every so slight a few seconds in.
Does it make a difference? You're right, no. If you're having to struggle to use these power tools, chances are youre using the wrong tool/doing it wrong.
Dewalt tools work peak at most prestige in UK construction industry. I do see occasional milwakee, mostly drywall guys I guess. Most are makita, but there's defo prestige with Dewalt 🤣😁
For me it's more about the occasional screw/attachment 🤷🏼♂️
Thanks for watching. That’s right, on the smaller tools like the ones I had in the video it doesn’t make that much of a difference although I do think that 5ah batteries have the best value since you get so much more run time for not much more money and I find that they make the tools more balanced in the hand. The UK construction guys do seem to like Dewalt a lot, I have a friend who used them when he was working there but I’ve started switching to Makita mainly because they’re built better.
👏👏👏👏
My 1.5Ah battery last for 10 seconds is that normal?
Which tool are you using it on?
Thank you for reaching out. Sorry I just found out I was not charging the batteries right. I was not pushing down on the battery when charging. Thank you for reaching out I really appreciate it.
I did that the first few times too
I use the 18V XR charger to charge my 18V max, it's not work, Why? But 18V is no problem.
I don’t quite understand your question. What do you mean by 18v max?
Damn I know that screw was blazing hot
A fresh piece of wood and five less beers would of given me the enthusiasm to see it out
🤣 Great comment
Gloves young stud
cyril kanda gloves?
the higher amp-hour rating gives longer run time, not so much power more power
All sound the same to me
I'm sorry bro ....but you hottit wrong using small tools. Amphr is Extends your Run time not power. Go up in volts can change things.
You should pony tail your hair when working with power tools
Son, Get a hair cut please. That hair will get caught in something sooner or later.
Also when you hold power tools make sure things are not wobbling around.
The tool should be upright and drilling straight down. Posture is everything.
Good video though. I would have to get a 5.0 A battery now.
Só uso Dewalt porque aguenta pau.
personally learn how to use power tools properly before make a video 😂
