Are Cheap Power Tool Batteries better than DeWalt 20V OEM Lithiums? Let's find out!

when it comes to battery power tools I like just about everything about them except for one thing when it comes time to replace the batteries because they're worn out it's very expensive oftentimes the replacement batteries cost more than the tool itself so the question is should you take a chance and buy some cheap aftermarket batteries or should you stay with the name-brand ones I paid more than twice as much for name-brand batteries compared to the cheap aftermarket ones so let's do some testing on them and see if the DeWalt brand is really worth more than twice as much you'll see how each of the brands performs using a high energy drain test powering up three halogen lights then we'll see how these batteries perform using a much lower energy test powering up just one halogen light we'll see how the cold weather impacts that performance these batteries at below freezing temperatures will take apart each of the battery packs and then do some testing on the individual cells the least expensive battery we'll be testing is this van and 20 volt dwarf replacement battery costing twenty five dollars and fifty cents per battery or just a little over a hundred for all four well the batteries we will be testing our lithium ion 20 volt five amp Arab batteries made in China the phantom battery comes with a power to a battery user manual that covers battery tool use in care as well as safety information the second least expensive set of batteries we'll be testing is this Whateley brand costing $26.95 per battery about a hundred eight dollars for a set of four not as much on the back of this battery compared to the van end but it is made in China the Whateley is on the left the famine is on the right both batteries look strikingly similar there's a little bit of difference in the plastic housing as well as the color of the LED lights [Music] right at the van end the Whaley actually comes with a much better set of instructions it even provides information on which one of these is the anode as well as the cathode according the back of the instructions if you're not planning to use the power tool for three months you should separate the battery from the power tool storage temperature is from 20 to 30 degrees Celsius or 68 to 86 degrees Fahrenheit a price of fifty eight dollars and 94 cents or two hundred and thirty six dollars for four of these batteries these dwelt batteries cost more than twice as much as a cheap replacements unlike the cheap batteries these come with a three-year limited warranty there appears to be a manufacture date stamped on the battery the cells are made in Malaysia and packed assembled in Mexico lithium-ion family'd batteries weigh 523 grams Whitley brand weighs 593 grams quite a bit more in the DeWalt batteries weigh 630 Wow quite a bit of difference the DeWalt battery weighs quite a bit more than the other two brands the question is is it the plastic housing or is it actually the battery packs later in the video we're gonna disassemble these battery packs and weigh the cells in the first test we'll be testing these batteries out using this two wall power station I'll install each of the four batteries inside the power station then we powering up three 500 watt halogen lights we're gonna see how long these lights will run additionally we'll monitor the temperature these batteries will be using this kilowatt device to moderate performance of these batteries once the power level the batteries is low the power station will beep once every 30 seconds the duo power station is designed for 3,600 surge watts and 1,800 continuous so the three halogen lights will be drawing somewhere around 1500 watts continuous which is well within the capability of the power station we'll begin with the least expensive battery the van the batteries were fully charged using this power station before the test the power station is putting out around 103 to 104 volts around 11.5 am showing one thousand one hundred and eighty six watts can't get an alarm in about three minutes and 54 seconds okay unfortunately the lights already shut off at four minutes and four seconds the pattern temperature is still climbing obviously the temperature inside the battery casing is a lot higher than the plastic itself way to give this a couple of minutes and see just how hot this becomes it's been several minutes now and the battery temperature has peaked at about thirty nine point five degrees Celsius I'm going to switch out the batteries and test the next brand the batteries start off at three bars is now showing one bar the second battery is also showing one bar one bar with a third battery one bar testing the Whateley batteries next the DeWalt power station is cooled off it's been about twenty minutes the batteries are fully charged 104.1 volts 1195 watts eleven point five two amps [Music] ok 7 minutes and 8 seconds then we ran out of power it's been several minutes and the battery temperature seems to have peaked at forty seven point three degrees Celsius one bar the first battery was at one bar this one's at two bars the third battery's at two bars and the fourth battery is at one bar so two batteries were at two bars and two batteries at one bar there seems to be some variation with the quality of these Whateley batteries the dowhat batteries are fully charged the time to beat is seven minutes and eight seconds for the wall 104 point two volts eleven point five amps almost 1200 watts [Music] well over 12 minutes and 30 seconds with a droite which is about five and a half minutes longer than the competition if you took the runtime of both the Whateley as well as the vannin and added them together the DeWalt still lasted as long as both of them combined the DeWalt battery picked out at 53 point two degrees Celsius one bar with the de Waal the second battery 1 bar 1 bar 1 bar so the DeWalt batteries performed very consistently the high drain test really put all the batteries to the test and the vannin really struggled lasting just 244 seconds or a little over 4 minutes the Whaley did quite a bit better at 428 seconds but still far short of the DeWalt 751 seconds since the DeWalt cost more than twice as much would you be getting a better value by buying twice as many cheap batteries for nearly the same cost as the DeWalt for high drain applications buying two vane ends still doesn't match the performance of one set of dEWALT's however buying two sets of whateleys actually provides about an extra minute and a half of runtime compared to just one - all last test is really about measuring high drain capacity of each of these batteries up next gonna test a lot slower drain this time only using one halogen light the fan of batteries have been fully charged and off the charger for at least an hour all the batteries are full 3 bars [Music] the pet is out of juice at 21 minutes and 10 seconds the battery temperature is now at thirty six point six degrees Celsius these batteries seem to be peeking out at thirty seven point seven okay all the batteries at one bar testing the Whateley batteries next [Music] The Phantom batters last around 21 minutes in the whateleys have lasted 33 much better up next let's tested the wall all the batteries are one bar the wall batteries are fully charged [Music] okay the DeWalt lasted 41 minutes in about 30 seconds compared to Whateley which only lasted 33 minutes so an extra 8 minutes added wall the temperature seems to have peaked at 40 point 4 degrees all the batteries perform much better under a moderate load with the vaiman lasting one thousand two hundred and seventy seconds compared to 1983 for the Whaley and two thousand four hundred and ninety two for the DeWalt since the DeWalt cost twice as much as the cheap replacements buying twice as many cheap batteries as the DeWalt is pretty much a break-even strategy on the Van Daan's but the Whaley actually appears to be a terrific value of course this assumes that each brand of replacement batteries will provide the same number of battery cycles which is unlikely to be the case we're about to find out just how well these batteries perform when they're very cold now these batteries were stored outside all night and the temperature outside right now is about 17 degrees Fahrenheit now our temperature gauge is showing one point eight degrees Celsius for the battery which is very close to freezing point but it's actually colder than that out here [Music] [Music] the cold temperature is definitely taking his toll on the Velen batteries with about two minutes less of run time up next testing the Whateley all the batteries had one bar just like we saw with the van and the Whateley also lasted about two minutes less [Music] [Music] the cold temperature seems to have had less of an impact on the DeWalt compared to the Whateley in the vein and only losing about 30 to 35 seconds for the DeWalt the cold temperature had an impact on all the batteries shortening the runtime of the cheap replacements by over two minutes and the DeWalt by around 30 seconds up next I'm gonna disassemble each one of these batteries we'll take a look at the internal components 3.6 volt 18 650 batteries what's not available on the battery though is the milliamp power rating so I'm good and disassembled these batteries and look at a closer look at each one of them imma go ahead disassembled 18 650 batteries Savana batteries were three point six volts these Whateley batteries are 3.7 what's very interesting is they're advertised as 7.4 watt hours and if you take 10 times 7.4 you get 74 in these 20 volt batteries are supposed to be 100 watt hour batteries I'm go ahead this assembly 18 650 battery the 18 650 battery in the DeWalt is made by samsung the dual battery case is on the left and the vaiman is on the right now as you can see there's just a lot better quality with the DeWall the vein and battery weighs thirty seven point seven six grams the DeWalt battery weighs forty three point seven nine grams which is six grams more than the van end but the DeWalt and weight lead are very close to the same way the next time i measure just the plastic cases for each of the battery packs testing the van in 104 point six five grams 106.5 for two grams heavier one twenty three point four six so the dwell case is somewhere between fifteen and seventeen percent heavier each of the battery packs includes ten of these 18 650 batteries so do any of the brands honestly deliver a hundred what hours is advertised we're about to find out I'll be using the Opus bt 3400 to measure the internal resistance and milliamp hour capacity of each of the cells now that the batteries are fully charged let's measure the internal resistance so what's internal resistance internal resistance is the opposition of current flow within the battery a battery with low internal resistance can meet high energy demands that you would expect any power tool battery so we want this number to be as low as possible the internal resistance of the family batteries after four charge and discharge cycles is sixty five and seventy seven the whateleys did a little bit better on average at 52 in 69 the valence only produced 1411 and 1427 milliamp hours which is rather poor for an 18 650 cell Kuwait Lee did much better at 2208 and 2,205 milliamp hours the batteries are fully charged and the internal resistance is 56 and 57 for the DeWalt batteries which is slightly better on average than the famine and the Whateley batteries the DeWalt produced two thousand four hundred and sixty two and two thousand four hundred forty nine the milliamp hours which is the best of the three brands compared to the Waitley the doís produced approximately 250 more milliamp hours for each cell or 2500 milliamps for a battery pack of 10 18 650 cells all of the 20 volt batteries are rated at 5 amp hours or 100 watt hours so do any of the battery packs actually produce 100 watt hours one Vanden battery has a milliamp hour capacity of 1420 according to the Vanneman battery it's rated for 3 point 6 volts so all 10 family batteries would have any 14200 milliamp hour capacity for all 10 cells at 3 point 6 volts which is only 51 watt hours 10 Whateley batteries for a total of 20 mm and 70 million hours would produce 81 watt hours at 3.7 volts so the Whateley batteries actually performed a little bit better than a 74 watt hour rating that's printed on the battery wrapper the DeWalt at 3.7 volts in 2000 456 milliamp hours makes 91 watt hours so all the batteries fall short of the 100 watt hour rating but the DeWalt was by far the closest while cheap replacement batteries don't seem to live up to their what our claims that doesn't necessarily mean that they're a bad battery or a bad value another way to look at value is to consider the number what hours you're able to buy for a dollar looking at it this way the Whateley is by far the best value then the vannin and finally the de Waal of course this only takes into account initial performance and not the long-term performance of each brand I was really surprised at least one of the two cheap replacement batteries performed better than I anticipated the Whitely brand actually didn't do too bad especially when you consider the really affordable cost now with all that being said if I were to buy a brand new tool I would definitely want to go with the de Waal name brand however I just recently paid about thirty five dollars for two batteries from my old XRP 18 volt drill and the reason for that is the drill is just not worth spending a hundred dollars on replacement batteries I'd rather replace the entire drill than to go with new batteries for that drill which is just about worn out all my video ideas including this one come from viewers I hope you'll take time to give me a video idea I read reply to as many comments as possible thanks for much watching the video please take care and I look forward to next time
