They all suck long term, and under load, they all lose charging capacity after a few discharge cycles. I've yet to buy an off brand 6Ah dewalt battery that didn't lose capacity after a week or two of use. They lose a bar or two on the charge indicator, and as for the XR grinder, you can hear it no longer winds up to full speed once they drop a bar on the indicator, so it might be voltage drop vs capacity or a mix of the two.
I have some of the waitleys . They have been the best aftermarket ones I've ever bought. I've tried all the ones you tested and others. The waitleys have been great for me on my dcf900 1/2" impact gun. And my XR angle grinder.. they require quite a bit of juice. I have had 4 of the waitleys that have lasted me almost 6 months, as of now. With everyday use out of them. In case anyone is wondering..
@@carlcornelius4710 yea , mine are still fine . The cheaper ones that say lithium on the side. Stay away from those.. but the waitleys have held up good for me ..
You came to exact same conclusion as I have - Waitley is a great value. I have quite a few. The Waitley 6ah is better than my OEM DeWalt 5ah (Chinese knockoffs always overstate ah). All my Waitley's have lasted at least 5 years - not one has failed or noticeably degraded.
I just bought 2 Waitley 6Ah 20v batteries and 2 DeWalt 5Ah 20v batteries from Amazon. I tested each battery and while the DeWalt did indeed have Samsung 25R batteries the Waitley batteries had ZERO writing on them. Next I performed a capacity test and found the Waitleys were 3883 and 3863 mAh batteries closer to 4 Ah batteries and not the 6 Ah as advertised. The DeWalts tested at 5123 and 5092 mAh each surpassing the 5 Ah as advertised. I have both genuine Samsungs and Molicel batteries for replacing the batteries in the Waitleys when they die.
The aftermarket 18650/21700 cells used in these battery packs are not using high amp discharge cells, so they can't handle high amp applications like the grinder (with a load) for long. They'll overheat and degrade faster as well (less charging cycles). Some of the best cells out there are made by Samsung and Panasonic, which the cheap clones aren't using (can't use at those prices). I'm curious as to what brand cells DeWalt is using. I build drones and have tested dozens of various brand/model 18650 batteries.
I plan on buying the cheapest battery for the shell, then welding the highest quality cells I can put in there. Hopefully the driver chip can handle it. If not, I can get a driver too and make it work
I have a pile of these off brand 6ah batteries, seat of the pants testing puts them right between my Dewalt 4ah and 5ah batteries. Your testing is right in line with my experience. I am happy with the $30 ish dollars I spent on them. Good video🤙👍👍
I would much rather see things like this than an obviously sponsored "review" of a $4000 grinder I can't justify buying for my hobby. I'd love to see more things like this from your channel, and will continue watching and learning.
I just completely rebuilt one of mine with some Samsung 25r cells it feels much more powerful than the dewalt oem ones I have not ran it through the paces however once I do I might be building my own if it comes out well
This is awesome, good to see where a knock preforms well enough and where it doesn't. I always wondered if the real batteries were just huge market up, and this shows, not exactly. Looks like the name brand are probably more expensive for a reason, but the average diy'er might not need all that instant power. I got 3 knock off tool batteries that work great, but never used them on something like a grinder.
I bought a pair of Waitley 6ah batteries ($54 for 2) specifically for my Dewalt fan. They run for 4hrs on high speed. The 5ah Dewalt lasts 4.5 hrs in the fan but are $175 for a pair.
I started watching and thought to myself, "this seems similar to Project Farm" (which I really like). Right after that, it was mentioned that those were the inspiration for this and a recommendation to check them out. I am a subscriber now; cool shout out and nice work!
Waitley by far makes the best aftermarket batteries and is all that I buy now days, if I'm going to get aftermarket. They use Samsung cells in my m12 batteries. I still recommend going genuine with a warranty
Red Beard: THANKS!!! A really thorough review and very helpful results: Light duty: Waitley; Heavy Duty/High Torque: DeWalt. Thanks also for the citation of inspiration of Project Farm. However, your procedure was just as standardized and just as thorough. I appreciate the time you put it to make this a true test and the results are very useful. I am very appreciative.
thank you for this video bro. I am in the market of replacing my old dewalt batteries. I was looking into aftermarket batteries mainly to power my drill, rotary sander/ polisher, and my dual action polisher. I own a small mobile detailing company and I use several cordless tools. After watching your video, I have decided to purchase a couple of 5 or 6ah dewalt batteries since they seem to dominate when it comes to high drawing demands. Thanks for this info.
I bought the ones that have the same color scheme as Dewalt but 12 AH and upgraded my son's 12v four wheeler. I got 2 for 140 and them batteries are amazing in his four wheeler and I use them with tools also. Great find. Mine are a little different then his.
I have had issues with several aftermarket batteries I have bought. The single observed flaw is the inability for them to produce a continuous flow of power. They will power my DeWalt DCE100 blower only in bursts. Even the highly rated Waitley will produce power to the blower for less than 60 seconds on a full charge. When I release the switch on the blower, pause, then re-engage it will run again for a period of time. These 'bursts' of power decrease in time below 75% power, and then diminish to 5 second bursts until the battery is near depletion. The original DeWalt batteries are 5+ years old and still produce full, uninterrupted power from full charge to depletion....
I don't use them enough to notice a difference and I've had these dewalt and the knock off's for this period of time , I was impressed with the knock offs . I all so got an adapter to use them on my black and decker weed trimer these out performed the black and decker batterys by a lot
I’m definitely feeling a lot better about my DeWalt OEM 3ah battery purchase for $45 brand new. Makes me glad I got a legit battery for only a few dollars more than a knockoff that would perform slightly worse or the same as it.
Thanks for this video. For me the real test will be how many times the knock off batteries can be recharged. Will they last as long in months or years as a true Dewalt? So I’d love to hear an update. I’ve seen in many Amazon reviews the knock offs died after a few months. Thanks again.
I'm really glad I actually finished the video. Under load, it's clear the Dewalts are MUCH better. I'm looking for batteries to run a chainsaw, which is much more similar to a grinder than a blower. Dewalt it is.
Dude! You're my guy. You have a shop and a home gym! I'm all in. I subscribed as soon as I saw the Rogue plates and Monolift attachments. On top of that your deadpan expressions made me giggle through the entire video.
Would love to see some long term testing also. I wonder how much leaving them uncharged for long periods of time affects them. They say it doesn't affect Li-ion, but that's not true. It might not be a major difference or they may not just crap out completely, but it definitely does something to the cells.
I've used four 6ah Waitley's for at least 5 years - still going strong. I keep them charged and rotate thru all my batteries (including my OEM DeWalt batteries) so none gets overused/underused. Fwiw, I bought a couple 12ah DeWalts last year with my lawn mover/chainsaw/weed trimmer - one failed after 6 months. DeWalt replaced it quickly without hassle, so that ~$300 price tag per battery was at least worth something.
From all of the research I’ve done thus far…it seems that if you desire a specific OEM performance (I.e. 5ah performance) you need to jump up 1 ah with the aftermarket and you’ll get it.
I got 2 batpower 4ah compact batteries off amazon they have 21700 cells instead of 18650 paid $80. I had to cut up 4 large steel reels with a sawsall after draining my 2 dewalt 5ah batteries used a knock off 6ah battery and it didn't make it through the first cut and destroyed the battery so used the batpower to cut up last reel no problem and checked the charge and still was showing all the light bars. One thing I like is how much better these batteries fit in my tool bag when on a drill. Dewalt also makes a 4ah compact battery but haven't tried one
I think I may stick to my corded Dewalt grinders for now. I been currently looking at the 20V Brushless grinders and these knock off ((6AH)) batteries to keep cost down. This video gave me the information needed to answer my questions.
Cordless Dewalt grinders kill batteries I’d only recommend them for mobile jobs or where power outlets aren’t close by. The batteries get very hot as well when grinding
Very nice video and thanks for taking the time to put it together and show some bottom line analyses. It's good to know the higher price of the OEM is not just fluff. Also good to know there may be options.
you pushed a lot harder with the 6Ah, thats why it went through so many discs. to somewhat standardise this test you shouldve just let gravity pull the grinder through the material. the blower test was insightful though!
Cool review. I bought a Waitley years ago when I didn’t have funds for another Dewalt battery and I just needed something as a back up to my two 2.0 Dewalt batteries. I now have several more and larger DeWalt batteries but haven’t tested to compare but i use the waitley on a fairly regular rotation and don’t notice a huge drop off. It is a 5amp. Now I have a new Dewalt 6amp, 4amp and an older 3amp (and a flex volt). I should compare it to the 3 and 4 amp for time
Love project farm and found your video through suggestion, really appreciate the demonstration, usually I would say project farm tops tools comparison videos but your wider selection of brands is greatly appreciated!! Thank you
Thanks for the video. I recently bought a dewalt adapter for my dyson vacuum and I think aftermarket batteries will provide me a good cost efficient alternative to my dewalt batteries. Two of those waitlys should take care of my house on max settings and if the vacuum needs a proper dewalt, the money isn't lost as I have other dewalt tools that could use them.
I bought that adaptor to and after a 10 to 15 sec run time my Dyson shuts off. I have to pull my battery reinsert and then turn back on. I sent it back
Outstanding video! You are Very thorough in your testing. I purchased a knockoff battery from a seller on Facebook, and he must be selling some batteries that were throw away, by a manufacture to recycle as scrap, and they found their way to Facebook, to be purchased by an unsuspecting fool like me. Note to EVERYONE, look into the SELLER, BEFORE you buy anything.
I wonder if the Korea made dewalt batteries use the Samsung cells. They're not at the top of the 18650s form factor but they're near the top which might account for part of the performance difference.
Great review. Seems like the waitleys are probably so have 6 AH but higher internal resistances so have much higher voltage droop than the official DeWalt battery.
The other consideration is how they hold up over time/recharge cycles. I'd be willing to bet that you can get many more recharge cycles out of the DeWalt batteries (also justifying their higher cost), but it would be interesting to see if that is the case.
I sold a Dewalt saw to a construction worker. I was talking to him about eBay batteries. He purchased many. He said the all work great last about as long however after several months he said they started dying!
I really liked this video.I also think that I will not buy any of the k.o. batteries. My opinion is that none of them will hold up over a long period of time. Also the cost savings for a 5ah is not much. Thanks for helping me make this decision.
Thank you for your very detailed tests. One important parameter that you didn't measure is the performance after many charge/discharge cycles. Very good quality lithium batteries only drop 20% capacity after 1000 cycles which would never be experienced by a home handyman but could be seen by some tradesman. I have found that poor quality batteries can have reduced output after even as few as 20 cycles. Operating temperature also has a big effect on capacity so if you were going to do multiple cycle tests it would be good to let the battery cool down before and after charging as typical use would not have batteries being continuously cycled and always run hot. Lithium cells are made by very expensive machinery so the quality is usually consistent. The biggest variation is in the dishonest labelled capacity. The other way manufacturers can cheat is by having a very cheap Battery Management System (BMS) in the battery pack (or none at all). The BMS levels the charge across each cell, manages temperature rise and prevents over discharge which can wreck batteries.
Powerextra seem to have a serious quality control issue. The symptom is common to any rechargable batteries with multiplemcellsmin series. Broken battery balance. If you open up the battery to check up the voltage of individual cell, you will find at leastmone of them having less than 3.2 V or even worse, less than 1.0 V which means a dead LiIon battery. In many cases, when the balance wasnt broken too much, say individual cells have less than 0.1 V difference, then they will work as much as other 3rd party one and a quick balance charging will return them to a brand new state. Also, the DeWalt 6Ah seem to have 21700 cells which are literally overwhelming anything with 18650 cells.
I just bought some knock off Dewalt batteries and you’re totally right, they say 6 Ah but there is no way, because they are too small to be 6 Ah. It’s false advertising. I am awaiting a reply from the seller on Amazon about this.
Thanks man, just what i wanted to know. Never tried the off brands, not sure i ever will. I got some Dewalt 2s still working on my drill that are 10 years old
I got a adaptor to put on my daughters power wheels rzr for a 20v dewalt battery. I wanna buy some new batteries and charger for her and was hoping to find a cheaper version that will work on this adapter that is for dewalt style batteries
Great video. Thank you for the hi load testing as well. I am curious about the difference between the new and the used DeWalt 5Ah battery..and how these batteries fare with repeated charges and how quickly they degrade over time.. ie- after a fixed amount of charging cycles...say ten...what is the battery performance then? That would clinch the deal between the top contenders (DeWalt and Waitley.) You don't even need to bother with the rest. My question is how do they all degrade after repeated charging cycles.
Good timing. I've been trying to find some good reviews for aftermarket replacement batteries. Waitley is at the top of the list at this point if they've got 18v batteries for my older Porter Cable tools. Great review.
I will NEVER trust Dewalt batteries again. I have 2 OLD Dewalt NiCd batteries. They still function fair. I have 4 Dewalt replacement Lithium batteries. ALL FOUR failed completely withing 3 months of their warrantee. Yes, I have tried the backfeed trick. Never again. I'll go Waitley. Thanks for the info.
First, fantastic video! I really appreciate reviews for products that perform well and save me money. Next, you should probably proofread your description. Project Farm is a legend, not a leged 🤣. I’d love to see more extensive reviews, with more tools tested. Expecting good things from you!
5 and 6 ah packs will all be using 5S2P layout of 18650 cells, the difference will be in the cells, being 2.5ah or 3ah (claimed), so the weight difference would be minimal. 3Ah is about as high as you can go in 18650, and in cheap cells this would only be achievable at low current draw.
@@Thanosisnotreal because they don't. Just like Milwaukee's H.O. batteries (high output) as opposed to the XC (extended capacity) the 18650 cells have been upgraded to 21700 cells. FYI in case you're unaware...18650 cells are 18mm wide 65mm long. The 21700 cells in the new 6ah 21 mm wide and 70mm long. Larger cell=greater current, higher discharge, and more capacity. Configuration is exactly the same. 2 groups of 5 cells connected in series to increase voltage from 3.7v to 18v. Then the two rows connected in parallel doubleing the capacity. Hope this helps. And it all comes back to quality cells. Quality 18650 cells always weighs 40-45 grams. If you have a complete battery under 400 grams you can be sure it has cheap no brand Chinese fake or low quality cells. Open one up sometime and see Google the data sheets for the cells used.
@@jimbaileyme I suspected they were larger cells . Thanks, I do have a few off brand “6 ah” packs. They perform about like the Dewalt 4ah packs, China maths. I’ll have to open one up and have a look…
So let me know what yall think about these results! Should do more videos like this one in the future? ------ Quick Update: The new shop is coming along. There is a hydraulic press restoration and numerous knife builds in this channel's future! Cheers yall. 🙌
Man, I didn't even know that there were after market batteries made for DeWalt.
The fake china batteries work good for a jobsite radio
But thats only it,
They all suck long term, and under load, they all lose charging capacity after a few discharge cycles. I've yet to buy an off brand 6Ah dewalt battery that didn't lose capacity after a week or two of use. They lose a bar or two on the charge indicator, and as for the XR grinder, you can hear it no longer winds up to full speed once they drop a bar on the indicator, so it might be voltage drop vs capacity or a mix of the two.
Do you have a 5Ah Powerstack? I wonder how this compares in the grinder test?
@@europana7 Sorry I don't
I have some of the waitleys . They have been the best aftermarket ones I've ever bought. I've tried all the ones you tested and others. The waitleys have been great for me on my dcf900 1/2" impact gun. And my XR angle grinder.. they require quite a bit of juice.

It's best to store at 50% charge, in a cold place.
Great methodology! Love my DeWalt tools, hate how pricey the batteries are. That Waitley will be perfect for extra batteries when we’re out w the RV.

I wonder if the Korea made dewalt batteries use the Samsung cells. They're not at the top of the 18650s form factor but they're near the top which might account for part of the performance difference.
Great test. Thank you.
Glad you liked it! Cheers!
Awesome video! Very helpful
Appreciate that! Glad it helped.
Thanks so much, really appreciate it. Without this review I would be scared to buy aftermarket batteries. Really good detailed review 👍
Glad I could help
Yes thanks for this video ! It has answered a lot of my questions about buying batteries
Glad I could help!
I like this review especially it includes the performance data(mph) in addition to the run time
Glad you liked it!
Great review.
Seems like the waitleys are probably so have 6 AH but higher internal resistances so have much higher voltage droop than the official DeWalt battery.
The other consideration is how they hold up over time/recharge cycles. I'd be willing to bet that you can get many more recharge cycles out of the DeWalt batteries (also justifying their higher cost), but it would be interesting to see if that is the case.
You’re probably right there Doug!
This made me buy waitly knock off dewalt replacements and I just wanna say m.f. thank you !!!!! 😊
Glad I could help!
Thanks man. I cant justify buying the dewalt batts but they sure do work well. I'm in the market for generic but there are so many more now
I sold a Dewalt saw to a construction worker. I was talking to him about eBay batteries. He purchased many. He said the all work great last about as long however after several months he said they started dying!
Hell yeah. This was so helpful!
Glad it helped!
Now im grabbing waitly brand 😅😊 thanks for the video
Cheers!
Good analysis. I like how you aRe honest honest
Thanks Boris!
I love TH-cam, there a video for everything.! Thanks for making this !!
Glad you enjoyed it!
Great quick service, delivery
I really liked this video.I also think that I will not buy any of the k.o. batteries. My opinion is that none of them will hold up over a long period of time. Also the cost savings for a 5ah is not much. Thanks for helping me make this decision.
I appreciate the time and effort put into this video. Great stuff. Liked and subscribed.
Much appreciated!
Man I love the data!
THANK YOU SO MUCH, this is awesome stuff!
Glad you like it!
Not the hero we asked for but the hero we needed!
LOL
This the best test i find in TH-cam 💪💪💪
Wow, thanks!
Thank you for your very detailed tests. One important parameter that you didn't measure is the performance after many charge/discharge cycles. Very good quality lithium batteries only drop 20% capacity after 1000 cycles which would never be experienced by a home handyman but could be seen by some tradesman. I have found that poor quality batteries can have reduced output after even as few as 20 cycles. Operating temperature also has a big effect on capacity so if you were going to do multiple cycle tests it would be good to let the battery cool down before and after charging as typical use would not have batteries being continuously cycled and always run hot. Lithium cells are made by very expensive machinery so the quality is usually consistent. The biggest variation is in the dishonest labelled capacity. The other way manufacturers can cheat is by having a very cheap Battery Management System (BMS) in the battery pack (or none at all). The BMS levels the charge across each cell, manages temperature rise and prevents over discharge which can wreck batteries.
Good point! I'll definitely keep that in mind for future videos.
Powerextra seem to have a serious quality control issue. The symptom is common to any rechargable batteries with multiplemcellsmin series. Broken battery balance. If you open up the battery to check up the voltage of individual cell, you will find at leastmone of them having less than 3.2 V or even worse, less than 1.0 V which means a dead LiIon battery.
In many cases, when the balance wasnt broken too much, say individual cells have less than 0.1 V difference, then they will work as much as other 3rd party one and a quick balance charging will return them to a brand new state.
Also, the DeWalt 6Ah seem to have 21700 cells which are literally overwhelming anything with 18650 cells.
I just bought some knock off Dewalt batteries and you’re totally right, they say 6 Ah but there is no way, because they are too small to be 6 Ah. It’s false advertising. I am awaiting a reply from the seller on Amazon about this.
Good testing and good videos. Thanks!
Glad you like them!
Thanks man, just what i wanted to know. Never tried the off brands, not sure i ever will. I got some Dewalt 2s still working on my drill that are 10 years old
Right on
Outstanding video... Very well thought out! 🙏
Thank you so much 😀
I appreciate the time spent on you doing this, Great job 👍🏾👍🏾👍🏾
My pleasure!
This was an incredible video - just ordered 2 Whaitly batteries for what I do - thank you 👊🏼😉
Glad I could help!
@@RedBeardOps got em’ today charged them fully (Waitleys) and if I were blind it behaves like a name brand battery 👊🏼😂
@@reno7725 Good to hear! CHeers
I got a adaptor to put on my daughters power wheels rzr for a 20v dewalt battery. I wanna buy some new batteries and charger for her and was hoping to find a cheaper version that will work on this adapter that is for dewalt style batteries
I’d like to see this test re-run in 6 vs 12 months to se if the knock offs can sustain their value vs Dewalt.
Great video
Thanks! I keep the Waitley's around and they're still going
Great video. Thank you for the hi load testing as well. I am curious about the difference between the new and the used DeWalt 5Ah battery..and how these batteries fare with repeated charges and how quickly they degrade over time.. ie- after a fixed amount of charging cycles...say ten...what is the battery performance then? That would clinch the deal between the top contenders (DeWalt and Waitley.) You don't even need to bother with the rest. My question is how do they all degrade after repeated charging cycles.
Good question! I'm not sure. The Waitley has been working well for me so far
Awesome video! Thanks so much for sharing great information!
Glad it was helpful!
This was super helpful. Thank you for your hard work.
Glad it was helpful!
Good timing. I've been trying to find some good reviews for aftermarket replacement batteries. Waitley is at the top of the list at this point if they've got 18v batteries for my older Porter Cable tools. Great review.
Glad I could help!
Ty for these tests! I was just about to cheap out and buy some powtree batteries lol no more sir, oem Dewalt batteries only now.
Cheers sir!
I will NEVER trust Dewalt batteries again. I have 2 OLD Dewalt NiCd batteries. They still function fair. I have 4 Dewalt replacement Lithium batteries. ALL FOUR failed completely withing 3 months of their warrantee. Yes, I have tried the backfeed trick. Never again. I'll go Waitley. Thanks for the info.
Glad you enjoyed the video sir!
Hell of a video, thank you!
Glad it was helpful!
Thanks James! That really helps!
Happy to help!
First, fantastic video! I really appreciate reviews for products that perform well and save me money. Next, you should probably proofread your description. Project Farm is a legend, not a leged 🤣. I’d love to see more extensive reviews, with more tools tested. Expecting good things from you!
Thank you!
The 6ah DeWalt battery uses bigger 21700 cells, which gives more power and runtime
Thank you very much for the video , and your time.
Glad it was helpful!
Run and power test in the high torque 1/2" impact
Great video man!
Glad you liked it!
Excellent comparison! I'll bet you still have those old batteries laying around, any chance of an update on their longevity? Thank you
The waitly is still running strong. After the test I got rid of the others.
5 and 6 ah packs will all be using 5S2P layout of 18650 cells, the difference will be in the cells, being 2.5ah or 3ah (claimed), so the weight difference would be minimal. 3Ah is about as high as you can go in 18650, and in cheap cells this would only be achievable at low current draw.
THanks for the info Emyr
Why are the Dewalt 6ah batteries physically larger than the off brand if they contain the same 18650 cells?
@@Thanosisnotreal because they don't. Just like Milwaukee's H.O. batteries (high output) as opposed to the XC (extended capacity) the 18650 cells have been upgraded to 21700 cells. FYI in case you're unaware...18650 cells are 18mm wide 65mm long. The 21700 cells in the new 6ah 21 mm wide and 70mm long. Larger cell=greater current, higher discharge, and more capacity. Configuration is exactly the same. 2 groups of 5 cells connected in series to increase voltage from 3.7v to 18v. Then the two rows connected in parallel doubleing the capacity. Hope this helps. And it all comes back to quality cells. Quality 18650 cells always weighs 40-45 grams. If you have a complete battery under 400 grams you can be sure it has cheap no brand Chinese fake or low quality cells. Open one up sometime and see Google the data sheets for the cells used.
@@jimbaileyme I suspected they were larger cells . Thanks, I do have a few off brand “6 ah” packs. They perform about like the Dewalt 4ah packs, China maths. I’ll have to open one up and have a look…
@@Thanosisnotreal China maths, 😂🤣😂👍
For my money the Waitly wins hands down. I have spent about 2.5 years trying to murder one of these things. It’s still hanging in there.
Great job. Great knowledge 👏
Glad it was helpful!
I was hoping you would take them apart to count the cells and see if they have a circuit board inside.
Sorry to disappoint!
Thanks! Great and helpful video.
Glad it was helpful!
Very well done....thanks!
This guy must be an engineer. Great scientific approach. Would love to know how many times each battery can be recharged.
That would be a good test David!
Great video. Would of liked to see how these batteries compared using a circular saw, but I'll live.
Lol, thanks Jason! I'd imagine it would be similar to the angle grinder.
