Which 20V Replacement DeWalt Battery is the BEST? | Knockoffs VS DeWalt Comparison

[@RedBeardOps]

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. 🙌

[@MrDragonUTube]

Man, I didn't even know that there were after market batteries made for DeWalt.

[@promo130]

The fake china batteries work good for a jobsite radio But thats only it,

[@tdcjonm]

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.

[@europana7]

Do you have a 5Ah Powerstack? I wonder how this compares in the grinder test?

[@RedBeardOps]

@@europana7 Sorry I don't

[@gbii8101]

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..

[@ArthurDentZaphodBeeb]

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.

[@JTLeyva]

Thank you very much for your feed back that's what I needed to know looking for one to use on my keeds power wheels

[@steveanimatrix3887]

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.

[@cruikshank]

Where are you buying your batteries? I need to rebuilt some Hitachi Battery packs. Thanks

[@bluedistortions]

What's the best value brand in your opinon?

[@aspectratiogardenservices]

Dewalt uses Samsung.

[@beefstickswellington1203]

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

[@Wooskii1]

​@@beefstickswellington1203That's a good idea, dunno why I didn't think of it. Thanks for the idea

[@gorillamotors]

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.

[@Thanosisnotreal]

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🤙👍👍

[@rickybobbyracing9106]

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.

[@cedricwebb5576]

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.

[@RedBeardOps]

Glad I could help

[@cruikshank]

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.

[@hdwoodshop]

Great video. I was impressed by the R squared you calculated. Even that you knew what that was is impressive. Thanks for elevating the conversation.

[@RedBeardOps]

Hahaha, thanks man! Glad you enjoyed it! Hope you like some of the other videos.

[@ucnhtmenow1]

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.

[@RedBeardOps]

Long term testing would be good!

[@ArthurDentZaphodBeeb]

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.

[@ctrlaltdebug]

It's best to store at 50% charge, in a cold place.

[@jazbuilding]

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.

[@RedBeardOps]

Glad it was helpful!

[@beardo_M.D.]

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.

[@RedBeardOps]

Nice, glad to hear they're working out for you!

[@ThomasElmore-dh7pu]

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.

[@JeffreyHyun]

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.

[@cutweldngrind]

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.

[@RedBeardOps]

Cheers sir!

[@Nathang2233]

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

[@crystalparker9117]

Love the credit you gave to project farm, as well as the experiment. Excellent. Might I recommended speeding the audio up a little in the future? 😊

[@RedBeardOps]

Thanks for the tips!

[@theperfectpaintertoolreview]

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

[@corin164]

This is about the third or fourth battery comparison tests that I've seen. All of them recommended the Waitley if DeWalt's prices are a tad too high.

[@psumurph]

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.

[@RedBeardOps]

Thanks!

[@nickeast6784]

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.

[@KosmicHRTRacingTeam]

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

[@MrMarmite99]

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

[@alanseager]

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

[@ChesterTheSpider]

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.

[@RedBeardOps]

Glad I could help!

[@scrapple8741]

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

[@dwightalbers5241]

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....

[@RedBeardOps]

Interesting, I haven't had that issue with the Waitlys I own yet, but I agree the dewalt batteries OEM are king

[@carpo719]

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

[@lcdubs7847]

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.

[@RedBeardOps]

Cheers!

[@revoldrofnugoblarevoldrofn9278]

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.

[@quimerammg]

Amazing video! You made me decide which one I'll get. Thank you a lot!

[@somebeinganonymous]

Great vid, and appreciate your efforts in making it. Will deffo give the Waitley a go!

[@RedBeardOps]

Good luck! Thanks

[@NerdyCats3]

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.

[@RedBeardOps]

Good question! I'm not sure. The Waitley has been working well for me so far

[@dperreno]

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.

[@RedBeardOps]

You’re probably right there Doug!

[@BillyBuckets951]

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'm not sure about that Abel

[@chrispolasek6719]

DeWalt 20v is actually 18v. It's 20 volts measured straight off of the battery, it's 18v under a load.

[@tigercat8905]

Picture a 12v battery in your car. Your system is a 12v but your alternator charges it 13.5-14 volts. So is it 12v or 14v system? What I am saying is " 18v tools and 20v nominal is exactly the same thing." Overseas their new dewalt stuff has 18v written on them. This is why all the 18v and 20v tools will run off each other's batteries when using adapters. It's just misleading jargon. Would you rather buy one get one free for 10.00 or buy them two for 10.00. Same thing just a play on words.

2.5Ah? The batteries that came with my drills were 1.5Ah. I got robbed lol. I also have two 4.0Ah batteries but I guess it's time to look for 6-12Ah , but they just cost so much.

Yeah, they aren't cheap for sure

Do you know any knockoff 20v angle grinders that use dewalt style batteries?

[@RedBeardOps]

I do not, sorry!
