For sure. You know you're getting a good quality show every time. I watch, whether the test involves something that interests me or not. Just a great job.
Agreed - not so much just 'because he invests time' - more when something should take time/effort, it's used. I never see something being tested and feel I'd want it done any other way.
I think some of these studies you are doing are priceless for people that don't have the money to buy it and do it. Saying that we can find out the best bang for our buck, I just wanna say thanks for the good content and the outcomes of the experiments.
yeah i really think it's super helpful in deciding what to buy. it just so happens he reviews a lot of the stuff that I also want to know which is best to buy so that's great.
@@ProjectFarm whats better lithium ion rechargeables or nimh? it seems nimh might be better for my needs as they discharge slower/have a greater capacity? but also dont have to buy a costly charger specific to lithium is that correct?
It's great to see you're still replying/taking suggestions from comments after the video has been out for so long, you are by far one of the most dedicated channels ever on RU-vid. Thank you for your constant insight on consumer products, you've been a great help to both my dad and I when it comes to choosing the best bang for buck products!
I'm glad you didn't test the EBL's I tested yesterday. LOL Some of those Li-ion batteries did very well, I like the micro USB charging feature. I was surprised to see the voltage drop as much as it did under load. Thanks for another fantastic testing video, and the NiMH update!
You did an A+++ job with your testing!! Thanks for the positive feedback! Here's a link in case others want to check it out! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HRaa5Joe3bI.html
The Li-ion AA batteries have electronics for charging and a buck for voltage..They will limit performance over a primary cell, take up space and so on. The performance limitations include voltage drop under load. This is not the cell impedance but the electronics also minimising current availability. This is guess work but I assume it is this way.
@@ProjectFarm I want to know if there is a charger that will keep more than just four fully charged and maintained. I am a mechanic in a shop with a LOT of heavy equioment, and I use a headlamp extensively, and I go through a LOT of batteries, for the headlamp and flashlights. I would love to know if such a charger exists, and how well they stack up. Also, a workup on solar chargers would be nice, too.
Yeah, I have a bunch of EBLs. Goofy how they have to be charged in pairs. A lot of devices, like flashlights and headlamps for example, use 3 batteries. Makes charging equally drained batteries near impossible.
@@ProjectFarm please test a reputable brand like norseman or drill hog usa made drill bits, m42 cobalt vs m7 molybdenum drill bit in hardened steel or grade 8 bolts. M7 can tolerate higher heat, but m42 is harder.
@@hdezn26 You should check out the CAT S60 series cell phones. As a mechanic i use the S60 as my personal phone and work use. Tough as hell too. Much cheaper than most thermo devices and very mobile.
Love how all your test show exactly how they are performed with progress in between, that kind of transparency makes us users happy to see... it allows the users to choose their products based on results, not just showing a chart or a commercial. Keep up the good work!
Minister: "to have and to hold, in sickness and in heath, in good times and woe, for richer or poorer, keeping yourself solely unto her for as long as you both shall live?" Bride/Groom: "I do" Project farm from the audience: "We're gonna test that."
Omg !!! Is this the one that I requested? Probably a bunch of other people as well I'm sure, but I remember when I mentioned this one. Btw the usb chargable batteries are kinda cool.
Very cool, but I get the impression that they are all Chinese brands not technically allowed to be sold here. Probably not FCC licensed or whatever. Still, they are cool and I am open to trying one of them.
With 280 million views making these videos would provide a good part of the income, so my guess. If you are good at reviewing and do not accept bribes, then people will trust you. I must say that I am often surprised about how well he extracts what are the essential questions for the products, and knows how to find that out the answers. Then presents it in ways that almost everyone can understand. My criticism would be two points: - in the last time the speaking speed increased too much - the product bias is naturally US
In future battery videos, for both rechargeable and non-rechargeable, it'd be great to see a few other tests. 1) How well they perform after and/or during being exposed to heat or cold. 2) How well non-rechargeable batteries perform and how many cycles they last using specialty battery chargers designed for non-rechargeables. (Yes, those work and are safe if you follow the guidelines.) 3) How many cycles the standard rechargeable batteries last and how well they perform up till the end. And, finally, 4) How many joules can the batteries survive? For example, if there's a surge while charging or short circuit from device usage.
I ABSOLUTELY love the way you put (chapters) for each different brand of battery. So after I look at the results of the test, I can go back to the specific brand I warm up to. It all happened all at the same moment. I had this thought. I'm gonna tell him that a chapter for each item type, would probably be well appreciated. And I look, and lo. You thought of it before me. So, cheerio.
Other Reviewers: My tools aren't up to par, I just won't mention it. PF: My tools aren't up to par, so I will tell you and show you the new tool I bought for this. P.S. Here's what I bought (Link in the description)
Been subd for several yrs, & as a part x mechanical engineer, u never fail to impress me with new ideas & solid science! I have grown to trust ur opinion or fact without fail or 2nd guess, TY!
Was just thinking the same thing. Well, I can enjoy it now, lol. We sure as hell know kids these days wouldn’t go near a Gameboy since they have their ipads and such.
I have Eneloop batteries from a decade ago that I'm still using, those things last forever. My use isn't daily stuff, but things like an XBOX controller that only gets used here and there, but they seem to perform pretty well still. Compared to what was available at the time, Eneloop was probably two generations ahead of everything else. At the time I'd get Energizer or whatever else you could find on the shelf, and those things wouldn't last you 2 years, but these Eneloops are still going literally 10-years later (I got them 2011).
Same here, I have Eneloops that are also about 10 years old and are still working. Other rechargables had to be thrown away after 2-4 years. Same for AAA Eneloop. Greets from germany
@@apisrehman4760 you didn't ask me, but the Energizer Rechargeable I've bought over the last decade have not been very good. They have not been used much, and yet they still won't hold a charge after a few years. That's where the Eneloops are so good, they just seemingly last forever. Obviously the old ones aren't going to be full capacity 10-years later, but they actually work. Where as the Duracell and Energizer and Amazon Basics batteries, after 2-3 years, they rarely still work. Not sure why there is such a big difference, but that's been my personal experience.
I really appreciate you taking you time to do these videos. I check youtube every night for a new video from you.. I really appreciate the scientific way you take on these projects. I learn alot. I usually go buy the top performers in your tests. Thank you for all of your hard work
I'd like to see the ego brand tested in a cordless blower test. I have their hedge trimmer and it is a great tool that blew my mind the first time I uses it.
@@davewolf8869 there's a lot of ignorance surrounding systems of measurement. It is often displayed by calling US Customary Imperial. Imperial didn't even come to be until 1836. The US developed our system in 1789. We borrowed names from the ancient system but that's it. We may have used a liquid measure but then the Empire adopted another measurement? I can't remember all the details myself. Then at some later date we all adopted the international inch. Which only further confuses people as to what came from where. The inch we use today is neither the old US nor Imperial one. A Swede actually made it. He made the best inches in the world so everyone beat a path to his door. Ford ultimately bought the guy and imported him to the USA. When you're as rich as Ford was you could do that sort of thing.
I want to go to the metric system as well so it's easy to do math with measurements, and it works better conceptually. I don't understand the meaning of the metric system intuitively but I do use it often. Perhaps I should just switch to Celsius and get used to it. It would be hard for a while but I could easily learn.
@@beez1717 metric has no advantages making measurements. There are supposedly some advantages to metric making conversions. Although we have computers today that can perform those calculations for us. So that benefit is less critical. Essentially there's an app for that.
I am glad I discovered the MH-C9000. It is a safe charger in that it will not allow me to charge bad battery. I had a non-smart charger previously and was shocked to find some of the bad batteries dangerously heated up. This channel is the best!
Thank you for this great comparison! Choosing rechargeable batteries was always a hit or miss before. I have a lot of vintage handhelds, and stocked up on znter AA batteries and sorbo for AAA. I don't like the batteries with full size usb port because they're more bulky. The microusb batteries can potentially be charged on the fly, which is very convenient
This video reminds me that I would like to see a shootout on rechargeable headlamps. Milwaukee, Klein, Energizer, and Craftsman are my brand recommendations to test since they can be store bought
I have the Black Diamond Storm headlamp and was watching this to figure out which triple As might be best for that. I figured the AA performance would be mirrored in the AAAs
Love the videos and they have helped me make some decisions and save some money, absolutely awesome stuff! One thing I'd personally like to see is a test of waterproofing sprays/coatings.
Great video as always, and on a topic that is becoming a hot one! Am I mistaken or have you not made a AAA battery-comparison? Keep up the good job! I signed up on Patreon now!
Two quick questions: 1: Have you considered doing a "best headlight bulb" test? 2: What happens to the used equipment when you're done with it? Do you resell it to viewers? Maybe with an autograph? :)
Thank you for your years of dedication to give us feedback on things we use. I don't know how you haven't sold out like most RU-vid creators have. I wouldn't blame you for giving in to stupid app games or food services eventually. I mean you need to recover the cost of the things you review for us. Please don't ever let companies that make things we actually need and use sway you.
I love this guy he’s very entertaining and honest and should get more love also I think I speak for everyone when he says we’re going to test that we all get excited
Hot or cold tea? I actually have a blend that I've came up with. Email me your address and I'll send you a sample and let you "I'm gonna test that"! kenhurley50@gmail.com
As a photographer I've been using Eneloops in my strobes for years, I really can't fault them but it's interesting to see how they stack up against alternatives in real terms. The one thing I found they did better than the few others I tried was cycle flashes extremely quickly - so a high current draw over a short period of time repeatedly - many batteries just couldn't do it - even some supposedly 'high power' ones!
Your channel is the ABSOLUTE GO-TO for any kind of tools / hardware / electronics etc for me. I am finally in the market for getting a charger and a set of batteries, either Lithium ion or NiMH, and I would love to see an updated video on the state of Li Ion batteries now, 3 years later... The charger you have in your video, for example, I looked for and found that the company may have changed hands and the product quality went down the tubes.. I am looking at the brand new XTAR VC8S 8 bay multi chemistry charger / reconditoner / analyzer and a set of Lithium and NiMH batteries for two different applications.. Keep up the great work, NOBODY is a thorough, organized, and rapid fire as you are in your videos!
Nice video! I have been testing batteries for many years from Ni-Cad, rechargeable Alkaline, NiMH, and have found them all lacking in various degrees as noted in your video. My observation on NiMH is that the Energizer and Rayovac are not very good and Duracell and Eneloop are pretty good. In fact, my Eneloop batteries are so old, they were branded as Sanyo! I will keep an eye on the Lithium version as I have a few things that require the higher voltage that the NiMH has not been able to produce. As such, I still have to rely on disposable Alkaline batteries.
My biggest turn-off to rechargeable AA's has always been their inconsistency to run at a stable voltage or charge reliably over long periods of time. Using some that are stable at 1.5V would be something to consider.
WHAT? They run extremely stable at 1.2v They have a remarkably flat discharge curve. Only the cheapest and poorest quality and badly designed device does not work well with them. Because the discharge curve exists INSIDE the discharge curve of an alkaline or CZ cell, they work with any well designed device. The discharge curve of both alkaline and CZ looks like this \ where the nicad/nimh looks like this ------ with tails on either end.
@@nuclearexplosion5841 Right. And high-drain devices, which you would want to use rechargeables with the most, also tend to be the ones that don't tolerate the lower voltage.
What do you do will all these extra products , have crazy garage sales every year🤣 iv wondered for a while where the other 12 chainsaws and 17 coffee mugs that lost the competition go
@@ProjectFarm if you do...try putting glass over some of the solar panels as part of long term test? UV tends to make the resin on them go cloudy, but most glass blocks a lot of it.
One way to know you are good at what you do is this: when you aren’t trying to sell me something, yet I feel compelled to give you money anyway. Amazing job! That 2 year follow up on the rechargeable batteries earned you a Patreon subscription from me. Keep up the great work!!!!
Would it be weird if MR.PF wore a lab coat to conduct all his tests? I love the level of ingenuity that goes into all the tests. I used to watch the videos that only pertained to my potential purchases but now I just watch them just to watch.
IDK, but you, Sir, might be the most valuable human on youtube. God Bless You for your work, your conscientiousness, your honesty and your prolificness. Now, just please stay healthy! Mega Thumbs Up!
How about a showdown between different screwdriver tips so I can finally know if I'm justified saying torx screws are easier to turn and require less downward force.
@@SaneAsylum strap on be prepared to owe them for life and your unborn child some stuff is worth It others toolsbyou can get Harbor freight tools and save some money
Just use impact for everything. An impact driver re-seats itself after each impact, so it rarely strips out screws. The only downsite is that it's a bit more likely to snap the head of the philips bit. I've never seen a robertson bit snap, bit philips bits snap every few weeks or few months.
Thank you for your testing! I had to sift through the german Amazon to find any of those, but i settled on the Blackube, as all the others that i could find had stupid long delivery times. What i would appreciate though, would be an overview screen with all the values tested, that would be quite nice to have after watching and hearing your opinion
I’m curious to know why you list the batteries in remaining mAh rather than a percentage loss from their listed mAh rating? I’d rather buy a battery that does what it says it’s going to do than longest running out of all just because.
Great video! Just a thought, it might not be the best comparison between NiMH and L-ion if you discharge them at different rates with different instruments. But if you were just re-testing the NiMH batteries after hard use, then no big deal. Thanks for making these!
FYI, the "Smartools" links to a different brand now. A sesrch for "Smartools" (after a struggle w/Amazon "correcting" to Smartwool) produced no battery listing.
really appreciate these long term tests with the results included in the video. A lot of the time you will see the start of a test and then you have to check back in a year for the results video.
Great video! As someone in the automotive world I would love to see some testing on Octane boosters to see which brand is snake oil and which brand performs the best.
Vapcel makes good products, I have been using their analyzing charger for the last two years and it's been awesome. I run Duracell and Eneloop rechargeable batteries so I already knew they were good, nice to see it stands true here as well.
I know this is a year old, but between lithium rechargeable and standard rechargeable batteries, what would you pick? And do you have a favorite that you use at home? I am sick of using regular batteries, seems like such a waste. Definitely need aaa to start with.
@@livenhfree The nominal voltage is a good bit lower with NiMH batteries, which can be a bit of a nuisance for some devices that are dependent on their voltage.
Could you test these Li AA batteries for RFI (radio frequency interference) output? I've found that the Fuvaly ones I have can't be used in my Sony portable shortwave radio due to the amount of RF noise they put out. I wonder if some of these are better than others in shielding that kind of radiation from the voltage conversion circuit. The Dubious Engineering YT channel measured 3 battery brands (video: YCZxe0YoNBo) and found that they each used different switching frequencies in their voltage regulators. The base frequency would determine in which band the RF noise would be most prevalent.
Subscribing! Exactly what I was looking for. Some brands are not available in Europe but the Vapcell are as low as $6 each. Very professional tests, very much appreciated.
Wow thank you very much for this awesome and detailed test! Finally a honest and true review with actual test results in numbers!!! :) Im so happy now to know what to buy and what not!!! This should be in more tech sectors...
As I watch this, 31,000+ likes and zero dislikes on this video. Zero. Zilch. Zip. That doesn't happen with lesser content on RU-vid. Massive thanks to Project Farm for content that really helps ordinary people in the real world. Champs!
Don't know if you've done this or not but I use a lot of trail cams and have been considering going to NiMh or lithium rechargeable battery. I'm wondering which one performs best in cold weather sometimes it does get down to 0 F but usually 20 F. I also have a place that I use trail cams as a form of security which in January and Feb it can get even colder. Thanks.
@@ProjectFarm I'm also very interested in this. I'm looking for a rechargeable battery for night vision and a SCBA, both of which will be used in cold and hot weather conditions.
Your tests are there when I need them, thanks so much! Very interested in cold weather use. It's time for a 3 year test on those NiMH rechargeable, and a 2 year test on the lithium rechargeable, cheers!
My experience extreme cold my lithium batteries have a little more power then my nimh batteries. In more temperate ranges I don't see much difference . Extremes I'm refering to bellow -5 F Temperate I'm reffering to 10 - 80 F Over 100F my nimh ones freak out a little and notice a decrease in performance the lithium BMS shuts them off at 105F.
@@dragonrider3701 I’m surprised lithium worked at all. Remember when lithium tool batteries first appeared?? No one up north or the Midwest could use them in the winter. They’ve gotten better but even Tesla had cars seizing up and not recharging during that cold spell this winter. Made national headlines.
Man you're helping pilots out everywhere, AA's are highly stockpiled by us since the noise cancelling part of our headphones uses em, and they have to be replaced constantly. Last thing you want is your batteries blowing out in the middle of a flight. This is great!
Awesome content. I’m curious how well these Lithium hold up to long-term self-drain (charged and ready in a box), how much capacity they lose sitting in 100+ degree ambient for a month (hot truck for a summer) vs inside, and whether they’re more efficient on lower-load uses that generally last >24 hours between charges.
@@ProjectFarm I'd like to know too. I am currently looking into the best rechargeable battery for my mouse. I'd love to know what I can get especially in New Zealand its hard to get some stuff here.
@@RadioactiveFishSticks ahh i see. i use them for remotes and clocks only. so I got the IKEAs which were reportedly made from the same factory (I think it's Fujitsu) as the Eneloops. My friend's original Sanyo Eneloop has been long lasting too.
I would also recommend you look at the ratio of (1yr capacity) / (initial capacity), because looking at the raw capacities is kind of meaningless when all the batteries start out with different initial capacities. Percent drop in capacity (and voltage?) after a year is what's most useful.
