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

do any of these dewalt replacement batteries work as well as the dewalt batteries themselves let's find out alrighty guys i have a good deal of dewalt cordless tools and i've been in the market for replacement batteries now in doing my research for replacement batteries i have found a good deal of aftermarket batteries some may call them knockoffs that are not manufactured by dewalt the question is are these aftermarket batteries as good or better than the original dewalt batteries today's testing will be an attempt to answer that question i'd like to note that this video and its structure are highly influenced by the project farm channel i have used his product videos in the past to intelligently purchase tools and i guarantee that you will not be disappointed if you check out his channel and with that let's get into the testing in the first test we will be using the dewalt dcbl 720 p1 to get some runtime results for each of these batteries the blower came with a 5 amp hour battery from dewalt and i will be using this 5 amp hour battery along with some other new and used dewalt batteries to get a baseline to get an idea of the air speed produced by each of these batteries we'll be using a wind gauge which will be clamped to the table in one stationary location for every test we will also be charging all the batteries to their full charge using my current dewalt chargers the first aftermarket battery that we will be testing today will be the weightly which comes in at 36 dollars all of the aftermarket batteries that we are testing today will be rated for six amp hours as you can see the test rig is fairly simple we have the blower strap down to the table with the air speed meter in front of it neither of these two items will be moved throughout the entire duration of the blower testing so we insert the battery into the blower depress the trigger all the way and lock the trigger in the full depressed location we then run the blower until the battery dies note that as the weightly battery dies the degradation of the air speed is very abrupt and this signature holds true for all the batteries we tested the weightly put up a score of 21 minutes in this first test the next contestants come from topbat which can be purchased in a 2-pack this results in a per battery price of 26. since i have two of these batteries i will be labeling one with a and the other with a b this is so that we can keep track of them during a testing and see if they have different performance even though they come from the same manufacturer we will be incorporating the same a and b labeling technique when testing the power extra batteries which also come in a 2-pack later on in the video it was nice to see that in both of these two packs tested the a and b batteries had similar results this shows that the manufacturing process for these batteries are uniform and repeatable both the a and b top bat batteries came in at around 17 minutes the next battery that we will be testing is the pow tree which is 33 dollars this by far is the most disappointing battery of the bunch i was not even able to get a full charge with either of my chargers on this battery within a few minutes of putting this battery on the charger the charger would start flashing the hot and cold delay light at no point in time were we able to get a full charge on this battery i'm not exactly sure what the issue was in this scenario but it does not bode well for the paltry test i decided to test this battery anyway so i charged it overnight even with a full night of charging the battery only showed that it had two-thirds of its charge like you would expect this battery was a very low performer and only ran for about six minutes in the blower test adding to the strangeness of this battery i removed the battery after the blower test to see how much of the battery's charge was left by pressing the indicator lights it showed that i still had two thirds of the battery life left the results were odd and i would not advise buying this battery for these reasons the next pair of batteries that we will be testing come from power extra and the per battery cost is 33 dollars like the top bat batteries these come in a two pack we will be labeling them a and b for our testing the power extra a and b pair compare very well to each other just like the top bat batteries did in the blower test the power extra a battery has a 15.7 minute time and the b battery had a 16.2 minute time these times were both lower than the top bat pair and the weightly battery the next batteries we will be testing are the used dewalt batteries one is a 5 amp hour battery that came with my blower and the other is a two and a half amp hour battery that came with my drill and impact driver one thing that i think we should notice here is that the dewalt 5 amp hour battery seems to have the same dimensions as the aftermarket 6 amp hour batteries do it is my hunch that all of these 6 amp hour batteries are really the equivalent to a dewalt 5 amp hour battery i think this will be more prevalent when we show the 6 amp hour battery in the next test the 5 amp hour battery used had a run time of 17 minutes and the used 2 and a half amp hour battery had a time of six minutes as you can see here the 136 dollar six amp hour dewalt battery is much larger than all of the aftermarket batteries that we have tested apparently when it comes to lithium ion batteries size does matter this new dewalt 6 amp hour battery made in korea performs significantly better than all of the aftermarket batteries with a blower run time of 24.9 minutes so here is the graph performance of all of the batteries in the blower runtime test the dewalt batteries are colored in yellow on this graph one thing to note here is that the weightly aftermarket battery not only outperformed all the other aftermarket batteries in the test but it also outperformed the used 5 amp hour battery from the wall when it comes to air speed the spread in performance was fairly close note the y-axis only has a spread of around 4.5 miles per hour however that being said the power extra batteries both consistently performed a little bit weaker in miles per hour than the rest of the pack in an attempt to find the best value batteries we calculated the dollar per run time the batteries towards the left side of this chart are better performers in this metric while this may not tell you which of the aftermarket batteries were the best since they are so close together i think it does indicate that the expensive dewalt battery may not be worth it for the average user as you saw i measured each of these batteries this chart shows the difference in thickness between the batteries tested i think this is probably a good indication of which amp hour these batteries really are note that all of the aftermarket batteries had approximately the same thickness dimension as our used 5 amp hour dewalt battery and the new dewalt 6 amp hour battery was much larger using the three dewalt batteries that we have in our testing we will plot runtime versus dewalt amp hours we have a two and a half a five and a six amp hour battery from dewalt the r squared of this correlation was .98 which is pretty darn good using this trend line we can calculate what the approximate dewalt equivalent amp hours are for each of the aftermarket batteries an example the weightly battery has a run time of 21 minutes which correlates to a 5.4 dewalt amp hour equivalent this bar graph shows how all of the aftermarket batteries stack up on an equivalent dewalt amp hour basis the weightly battery is the best performer when looking at this metric alrighty guys that was the air test now we're going to move on to the grinding test but before we do that we need to suit up [Music] for our next test we will be using these cut off wheels and the dewalt angle grinder each battery test will start off with a new disk and the clock will be stopped in between the disk changes the batteries will be graded on total run time and the number of disks they eat through when cutting a piece of three quarters of an inch rebar we will be testing the batteries in the same order so our first test will be the 36 weight lead battery one thing to note with the angle grinder testing is that i think it put a much larger load on the batteries than the blower did i'm also fairly sure many of these batteries are designed to shut down once a certain temperature or workload is reached in the grinder test the weightly battery was able to achieve a time of 3 minutes and 56 seconds before the pressing the trigger on the grinder would no longer turn the wheel i do think it is also worth noting that this was the only aftermarket battery which saw a decreased output towards the end of testing but continued to turn the wheel this is in contrast to all the other batteries that we will see coming up which just stopped abruptly the next battery up is the top bat i lost the footage for the a top bat battery however the results basically are identical with the be labeled battery the top bat had a grinder run time of 48 seconds this is around the time i realized how much more demanding the grinder was in the batteries than the blower the next battery tested was the power tree like i mentioned before this battery would not fully charge and this test is more of a courtesy since a good performance was not expected this battery only lasted 34 seconds before shutting off the power to the grinder after the poutry we tested the power extra batteries the a power extra put up a time of 3 minutes and 21 seconds which was close to the weightly and significantly better than the top bat the power extra b battery put up a lower time of 2.3 minutes this is the largest variation seen between battery pairs in the testing interestingly enough both of these batteries eroded approximately the same diameter of the cutting disc the 5 amp hour battery from dewalt put in an excellent performance of 4.4 minutes the time was better than all of the aftermarket batteries and i think it speaks to dewalt's high load performance the used 5 amp hour dewalt actually was able to make it through one and a half cutting disc which was significantly more than the aftermarket batteries the 2.5 amp hour used the wall battery put up a run time of 2 minutes and 5 seconds which is hilariously higher or close to some of the much larger amp hour rated aftermarket batteries this again is a testament to the grit of these dewalt batteries lastly we have the new 136 dollar dewalt 6 amp hour battery now i knew this battery would outperform the other batteries but i wasn't quite prepared for the magnitude of that outperformance the differential and run time between this battery and the rest of the pack was so great that i ended up running this test twice to verify it wasn't a fluke while i'm only showing one of the tests here i ran one iteration at the start of the grinding testing and the second iteration at the end of the grinder testing the results of these two tests were identical the six hour dewalt battery had a run time of 12.1 minutes and was able to make it through five of the cut off disc i laid out all of the used cutout disc next to their respective battery here other than the paltry the worst performer was the blue top bat batteries the power extra batteries and the weightly battery were the best aftermarket performers when it comes to the cut-off disc erosion the graph of grinder runtime performance shows a very similar story as you can see the dewalt batteries outperform the aftermarket batteries in this test and are clearly designed to handle the higher on-demand loads required with an angle grinder the aftermarket batteries that perform the best in runtime were the weightly and the power extra while the weightly put up a higher run time a portion of that run time was at a reduced rpm which is obvious when looking at the amount of the cutoff disc used by the weightly versus the power extra the dollar per run time on the higher power output grinder test paints a different picture than the blower test the 136 dewalt battery is much more economically competitive in tasks that require a high on-demand power output so that's how the testing shook out if you're looking for a battery that can handle high power output on demand then the expensive dewalt battery is your best option if you're looking for a lower duty battery that can handle drilling and impact operations or to be used in tools like the blower then i would highly recommend looking at the weightly it is a good cheap option and i feel like i will pick up a couple of these to have around the shop but enough about my opinions what did you think about these tests let me know in the comments below along with any other thoughts you may have on these testing procedures if you're interested in purchasing any of these batteries and you found this video helpful in making your decision i'll make sure to put my affiliate links in the description below also please consider subscribing to the channel if you want to be
