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

When it comes to battery

power

power

tool

s, I like almost everything about them except one thing: when it comes time to replace the

batteries

because they are dead, it is very expensive, many times the replacement

batteries

cost more than the

tool

itself, so the question is: Do you take a chance and buy some

cheap

aftermarket batteries or should you stick with the name brand ones. I paid more than double for name brand batteries compared to

cheap

aftermarket ones, so let's do some testing with them and see if the DeWalt brand is really worth more than double.

You'll see how each of the brands performs using a high-power test by turning on three halogen lights. We will then see how these batteries perform using a much lower power test by running just a halogen. In light we will see how cold weather affects performance. These batteries at sub-zero temperatures we will disassemble each of the battery packs and then do some testing on the individual cells. The least expensive battery we will test is this truck and 20 volts. midget replacement battery that costs twenty-five dollars and fifty cents per battery or a little over a hundred for all four.

Well, the batteries we will be testing are our 20 volt, five amp Arabic lithium ion batteries made in China. The Phantom Battery comes with a battery user manual that covers the use of battery powered tools in power care as well as safety information. The second least expensive set of batteries we will test is this Whateley brand which costs $26.95 per battery, about a hundred and eight dollars for a set of four, not as much on the back of this battery compared to the truck end, but It is made in China, Whateley is on the left, Famine is on the right, both batteries look surprisingly similar, there is a little difference in the plastic casing and the color of the LED.

It comes on right at the end of the truck, the Whaley actually comes with a much

better

set of instructions. It even provides information on which of these is the anode and cathode according to the back of the instructions if you don't plan on using power. tool for three months you must separate the battery from the power tool the storage temperature is 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 Used batteries cost more than twice as much as cheap replacements, unlike cheap batteries these come with a three-year limited warranty.

There appears to be a manufacturing date stamped on the battery. The cells are manufactured in Malaysia and packaged assembled in Mexico. The batteries in the family weigh 523 grams. The Whitley brand weighs 593 grams considerably more than the DeWalt batteries weigh 630 Wow, quite a difference, the DeWalt battery weighs considerably more than the other two brands, the question is if it is the plastic casing or is it? Are they really battery packs? Later in the video, we will take apart these battery packs and weigh the cells in the first test. We will test these batteries using this double wall power station.

I will install each of the four batteries inside. then we will turn on three 500 watt halogen lights, we will see how long these lights will work, we will also control the temperature that these batteries will use. We will use this kilowatt device to moderate the performance of these batteries once it reaches the batteries' power level. is low, the control panel will beep once every 30 seconds. The duo power station is designed for 3,600 watts surge and 1,800 continuous, so the three halogen lights will consume about 1,500 watts continuous, which is within the capacity of the power station. start with the least expensive battery the van the batteries were fully charged using this power station before testing the power station is generating around 103 to 104 volts around 11.5 am which shows one thousand one hundred eighty six watts no I can activate an alarm about three minutes and 54 seconds, okay, unfortunately the lights already went out after four minutes and four seconds, the temperature of the pattern continues to rise, obviously the temperature inside the battery case is much higher than the plastic itself.

So give it a couple of minutes and you'll see. how hot does this get several minutes have passed and the battery temperature has reached a maximum of approximately thirty-nine point five degrees centigrade. I'm going to change the batteries and try the next brand. Batteries start with three bars and now show one bar. the second battery also shows a bar a bar with a third battery a bar testing the Whateley batteries then the DeWalt power plant cools down about twenty minutes have passed the batteries are fully charged 104.1 volts 1195 watts eleven point five two amps ok 7 minutes and 8 seconds later we run out of power, several minutes have passed and the battery temperature appears to have reached a maximum of forty seven point three degrees Celsius one bar the first battery was at one bar this one is at two bars the third battery is in two bars and the fourth battery is in one bar, so two batteries were in two bars and two batteries were in one bar.

There seems to be some variation with the quality of these Whateley batteries. Dowhat batteries are fully charged. Blending time is seven minutes and eight seconds for battery. wall 104 point two volts eleven point five amps almost 1200 watts over 12 minutes and 30 seconds with a droite that is about five and a half minutes longer than the competition if you take the run time of both the Whateley and the Vannin and add them together , the DeWalt still lasted as long as they both combined the selected DeWalt battery at 53.2 degrees Celsius one bar with the Waal second battery 1 bar 1 bar 1 bar, so the DeWalt batteries very consistently performed the high drain test I really put all the batteries through their paces and the Vannin really struggled with lasting just 244 seconds or just over 4 minutes.

The Whaley did considerably

better

at 428 seconds, but still well below the DeWalt's 751 seconds, as the DeWalt cost more than twice as much. How much better value would you get by buying twice as many cheap batteries for about the same cost as DeWalt ones for high drain applications? Buying two paddle ends still doesn't equal the performance of a dEWALT set; However, purchasing two sets of Whateleys actually provides about an extra minute and a half of run time compared to just one; The whole last test is really about measuring the high drain capacity of each of these batteries.

Next we will try a much slower drain this time just using a halogen light that has the fan on the batteries. fully charged state and off the charger for at least one hour all batteries are full 3 bars the pet ran out of power at 21 minutes and 10 seconds the battery temperature is now thirty six point six degrees centigrade these batteries seem be peeking out at thirty-seven point seven, okay, all the batteries in one bar trying Whateley batteries next. Phantom batteries last about 21 minutes in Whateleys have lasted 33 much better. Next, let's test the wall. All batteries are in one bar.

The wall batteries are fully charged. Well the DeWalt lasted 41 minutes in about 30 seconds compared to the Whateley which only lasted 33 minutes so an extra 8 minutes were added. The temperature appears to have peaked at 40.4 degrees. All batteries perform much better with a moderate charge and the vaiman lasts. 1270 seconds compared to 1983 for the Whaley and 2492 for the DeWalt. Since the DeWalt costs twice as much as cheap replacements, buying twice as many cheap batteries as the DeWalt is practically a pain in the ass. even strategy at Van Daan, but Whaley actually seems to be excellent 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 discover how.

Well, these batteries work when they are very cold. Now these batteries were stored outside overnight and the temperature outside right now is about 17 degrees Fahrenheit. Now our temperature gauge shows one point eight degrees Celsius for the battery, which is very close to freezing point. but it's actually colder out here, the cold temperature is definitely taking its toll on the Velen batteries with about two minutes less run time. The next time we tested the Whateley, all the batteries had a bar, just as we saw with the truck and the Whateley as well. lasted about two minutes less, the cold temperature appears to have had less impact on the DeWalt compared to the Whateley in the vein and only lost about 30 to 35 seconds for the DeWalt, the cold temperature had an impact on all batteries, shortening the Run time of the cheap replacements by over two minutes and the DeWalt by around 30 seconds.

Next, I will disassemble each of these batteries. We'll take a look at the internal components. 3.6 volt batteries 18 650. However, what is not available on the battery is the milliamp power rating, so I am fine and took these batteries apart and took a closer look at each of them. Go ahead, I took apart 18 650 batteries. The Savana batteries were three point six volts. These Whateley batteries have 3.7. What is very interesting is that they are advertised as 7.4 watt hours and if you take 10 times 7.4 you will get 74 on these 20 volt batteries they are supposed to be 100 watt hour batteries. I'm going to move forward with this 18 650 battery assembly, the 18 650 battery on the DeWalt is made by Samsung. the dual battery box is on the left and the vaiman is on the right now, as you can see there is much better quality with the DeWall.

The vein and the battery weigh thirty-seven point seven six grams. The DeWalt battery weighs forty-three point seven nine grams. It's six grams more than the end of the truck, but DeWalt and the weight lead are very close the same way next time I measure just the plastic cases for each of the battery packs, testing the truck at 104, 65 grams 106.5 for two grams heavier. one twenty-three point four six, so the permanence casing is fifteen to seventeen percent heavier. Each of the battery packs includes ten of these 18,650 batteries, so either brand honestly delivers a hundred of the advertised hours we're about to

find

.

I will use 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 is internal resistance? Internal resistance is the opposition of current flow within the battery. A battery with low internal resistance can meet the high power demands you would expect from 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 fared a little better on average at 52 in 69, the Valence only produced 1411 and 1427 milliamp hours which is pretty poor for an 18 650 cell.

Kuwait Lee did much better with 2208 and 2205 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 Hunger and Whateley batteries. DeWalt produced two thousand four hundred sixty-two and two thousand four hundred forty-nine milliamp hours, which is the best of the three brands. Compared to the Waitley, the Dois produced approximately 250 more milliamp hours per cell or 2,500 milliamp hours for a 10-18,650-cell battery pack. All 20-volt batteries are rated at 5 amp hours or 100 watt hours, as are any of the battery packs. actually produces 100 watt hours, a Vanden battery has a capacity of 1420 milliamp hours.

According to the Vanneman battery, it is rated for 3.6 volts, so the 10 batteries in the family would have a capacity of 14,200 milliamp hours for the 10 cells at 3.6 volts, which it is. only 51 watt hours, 10 Whateley batteries for a total of 20mm and 70 million hours would produce 81 watt hours at 3.7 volts, so the Whateley batteries actually performed a little better than the 74 watt hour rating printed on the DeWalt battery wrapper. 3.7 volts in 2000, 456 milliamp hours generates 91 watt hours, so all batteries do not meet the 100 watt hour rating, but the DeWalt was by far the closest, while cheap replacement batteries do not.

They seem to live up to what we claim. This does not necessarily mean that it is a defective or bad value battery. Another way to look at value is to consider the number of hours you can buy for one dollar.Looking at it this way, Whateley is by far the best value. the vannin and finally the de Waal, of course this only takes into account the initial performance and not the long term performance of each brand. I was really surprised that at least one of the two cheap replacement batteries worked better than I anticipated, the Whitely brand really did.

It doesn't do too bad, especially considering the really affordable cost now, with all that being said, if I were to buy a new tool I would definitely want to use the De Waal brand, however I recently paid around thirty five dollars for two . batteries from my old 18 volt XRP drill and the reason is that it's not worth spending a hundred dollars on replacement batteries. I'd rather replace the entire drill than use new batteries for that drill that's almost worn out. All my video ideas, including this one, come from viewers. I hope you take the time to give me an idea for the video.

Read, respond to as many comments as possible. Thanks for watching the video. Be careful and I look forward to next time.
