The camera made the dying batteries so much more apparent. That was cool.

I definitely recommend doing a “best rechargeable battery” video. Test their starting power, how long they take to charge, how long they last, how fast the battery degrades, ext…

TLDR = 1. Thunderbolt Edge - 7:47:49 5 cents/hr 2. Energizer - 6:59:09 12 cents/hr 3. Amazon Basics - 6:33:52 5 cents/hr 4. Energizer Lithium - 5:56:34 33 cents/hr 5. Duracell - 5:41:12 13 cents/hr 6. Powermax - 5:05:46 4 cents/hr 7. AC Delco - 3:58:21 8 cents/hr 8. Thunderbolt Magnum - 3:35:46 8 cents/hr

I've never watched this channel before but it's nice to see that it has a lot of fans.

The lithium can just dump more power into the fan. It's just a fan and a switch. The lithium was running faster but didn't last as long. Overall it provides more power but kills itself faster.

Actually depleted batteries do weigh less than they do when fully charged, it's just that there is no consumer grade scale that is sensitive enough to detect the extremely small difference. It's a physics thing. A compressed spring also weigh more than the same spring in a relaxed state. .

I would love to see if the thunderbolt edge batteries are consistently this good within a pack or between the packs. Redoing the fan and light test with either a whole pack or a battery from multiple packs and comparing data for variation would be interesting

Tyler just sits in his garage and sits there for hours and is probably bored out of his mind to tell us how long a battery lasts, love this man.

its kinda scary watching him do semi-professional science. he's unlocked more of his brain.

The brilliant change of background, how much more perfect can you get? Great vid as always Tyler!

The idea to use fans on camera for this test was honestly just brilliant.

Personally, I love the dragging out! It shows how dedicated and intrigued you are. Love your videos, keep being you!

Finally there are reasonably affordable AA-sized Li-Ion rechargables. They are amazing. BTW, There is more to batteries than their longevity. Some batteries are better for heavy loads, others for long length at low currents, or under various surge behaviors, etc. Energizer ultimate lithium is also a favorite. Energizer alkaline are also very good. Eneloop NiMH batteries are fine if you can deal with 1.2V instead of 1.5. BTW, the expired batteries are probably micrograms lighter because of E=mc^2 and all that. EV's weigh a couple grams more when fully charged. It is not a nonsequitur to say that this is why people are so excited about the prospect of nuclear fusion. You have also demonstrated one reason why people prefer lithium technologies for EVs, power tools, etc: -- the output, after an initial fall-off, remains nearly constant until it drops below useful levels. Thus, devices can rely on full power until there is none, a good feature.

The best rechargeable AA battery's would be a good follow up.

I would be curious to see tests for national store brand batteries such as Walgreens, aldi, Albertsons, cvs, Kroger, Walmart etc. Otherwise I'll definitely be looking into the thunderbolts

Good for you for getting a sponsor. I find this video put together and much better than your normal test/comparison videos. The gold standard would definitely be any video from 'Project Farm'. Your lineup of fans/batteries was easy to see and actually measuring time for each was well done...actual measurable data which you don't often do, imo. In this test, for example, I'd recommend you get one of those RPM measuring devices and you could have measured rpm of each on the hour or something until they died. Anyway, well done and good improvement in your testing/comparison process and video. Keep it up!

The now sadly discontinued "Alkalisk" AA batteries from of all places Ikea were basically the best i've ever used that were non-lithium disopsables. Same with rechargable, the "Ladda" AA's from Ikea were just as good as, or often longer lasting than my eneloops.

video by video, tyler is working his way towards a phd in experimental physics. next step is when he pulls out the excel charts. you can do this tyler! edit: 29:47 - i spoke too soon, he has done just that! way to go tyler, you are getting more scientifically rigorous ;)

In middle school the duracells crushed it during a battery test for science class. Sad to see then fall. I think Amazon basics will be my next try. Would love to see store brand batteries tested since I work at Walmart, if those are good, then saves me a trip.

It's nice to see Tyler interacting so nicely with his fans!

Thanks Tyler. I been asking the same question for years. I always wondered what double a battery lasts the longest. I would of never thought In a million years that the thunderbolt edge would turn out to be the best battery.

Does anyone remember the Duracell batteries that you pressed and it showed how much life was in the battery?

Love how detailed this one was. Thank you Tyler! 👏👍

I don't know how I stumbled onto your channel -- but I'm hooked. really liked your mathematical analysis on the batteries 👍🍸

I'm always impressed how well many of the amazon basics products do.

Incredibly well done sir! Appreciate the great lengths you went to, to collect and record and present all of that data. I feel like we all have wondered this and I know different battery types are better for different applications but you really demonstrated things well and solid data presentation

I have to say I'm a fan of this video. the results really blew me away...

This is one of your best videos imo, loved it!

This was a really good, very informative video. Thank you very much for making this!

I remember when Energizer didn't have the Max. When the Max was being made, it was compared to the non-Max Energizer batteries. I guess they stopped making the non-max and just kept the labeling?

Slight critique. There could be manufacturing differences in those fan, especially if they are cheap. There could be pretty varying current draws from one fan to the next

The best part of the Thunderbolt Edge is that they go on sale all the time, so they are an even better value than what's shown in the video.

If you do this again, I’d love to see you include the batteries from dollar tree!

do it again with rechargeable batteries and once they die, do it one more time after you've charged the dead batteries

Excellent testing. You did a fantastic job showing us the testing and the results. The only thing I would add is to repeat to tests 3 times to get a better statistical sample and the results may shift a bit.

Thank you for this video. I love decorating for Christmas (this is Mike's wife, not Mike) and decorate my home early because I also decorate for clients. I have many items including garland, wreaths, tons of flameless candles, etc. in both indoor and outdoor décor that require batteries. Because I start early (October), my batteries do not last the entire season. I was googling which batteries last the longest. This is important not only from a cost perspective but also because many of my items are on top of kitchen cabinets and that requires a step ladder to change them and it is just not convenient when they have to be changed at least once after they are displayed. In addition, it is good for me to know in order to make recommendations to my clients for their battery operated Christmas items. My husband always leans toward buying the Thunderbolt Magnum, but the last two years, I've convinced him to purchase Energizer because I thought they'd last longer. We will now purchase the Thunderbolt Edge batteries. Not sure if the test results you did with the fans will prove the same with the candles and other Christmas décor I have, but I'm going to try it. Thank you again for this video and all the work you put into it. I will continue to watch your videos and am so glad I found this one.

Just wanted to say I can recognize how much work this took, I bet the post production work took twice as long as the filming. Good video now test how well different brands of flushable wet wipes break down

Try making an rpm measure of the fanblades with the Edge and the Lithium, you should see a decent difference. Lithium have a higher discharge rate, so they power things to the max from start to finish.

Ok, camera nerd here... lithium batteries tend to do best, from my experience, in high-drain non-continuous applications, like cameras and flash units. In that case, they pull really hard for a short amount of time and then sit basically idle until the next time the camera/flash is fired. I know that cameras (or off-camera flash units) will chew through alkaline batteries like candy, but lithium versions (and lithium-ion rechargeable) seem to fair a lot better. I put my Speedlight's rechargeable Li-ion batteries in a flashlight once just because I didn't have any new AA batteries handy, and it lasted about 1/3 the time it normally takes to run down a set of normal Energizers. And yes, for those of you thinking, "those rechargeable batteries must have just been worn out or charged badly or something," that was a fairly new set of batteries and they'd only been used in a smart charger. Alkaline and Lithium just seem to be optimized for different applications, from what I've seen

I normally won't watch videos that are over 15 minutes but this was very entertaining.

Can we just give a bit of respect to Tyler for thinking of these video ideas.

just a tip, put a damn timer in front of the runtine tests. it will save you the headache of figuring out later. also consider a battery discharge test machine. will tell you exactly how much power each battery has in MaH

Awesome job. Lots of great info! I think I'll be picking different batteries for different jobs.

This was a very cool video I loved it and I learned something. Keep up the great work Tyler! It means the world to me it really does.

the best battery that i remember using in every nerf gun is the radioshack enercel. they for some reason increased the speed of the motors making it shoot faster, and lasted just as long.

Lately I've been looking to try those newer style rechargeable batteries. They have almost all the sizes and they charge by micro usb. I don't think they last longer run time wise but the extended life and number of uses are suppose to be a major difference.

This is the kind of testing I like, maybe think about displaying your results in a more digestible way but keep up the good work 👍🏾

This was a fantastic video tyler

Just wondering how sharp an A4 battery can get...?!🧠

I loved the background 🤣🤣🤣 keep it up Tyler always doing a great job

The problem with Duracell is that we noticed leaving them in whatever your using them for, they tend to leak battery acid and you have to throw away your items, ie flashlight, Christmas decorations, child toy, etc. We switched to the Energizer which do not leak and corrode .

Great review. I really enjoyed it and learned a lot. Thanks for taking the time to do this great review.....

Surprised i didnt see Rayovac, maybe thats just locally available in my area. They are cheaper than name brand batteries so would be cool to see if the savings are worth it.

I've always found energizer to be better value and last longer than duracell - I was surprised to see how well Amazon Basics did though!

That lamp test was soooo good thanks for good day :D

Cool video, thanks. 👍 I like that battery backup thing as well, thanks for the info of that. ✌️

Damn you're getting more and more scientific with each video!

Thanks, Tyler, for doing all of this testing for us. If you ever do this again, it would be interesting to see what happens if you turn off the devices for comparable amounts of time during the test. I'm curious how much Peukert's Law would affect the results. Thanks for the video. Just sane... :^) Saint (Just sub'd BTW)

When a battery is advertised as "Lasting X times longer", They generally compare them to standard Carbon batteries or their most basic battery. Rarely they compare to opposition batteries of the same type.

Application is key here. I have an outdoor sensor for an indoor/outdoor thermometer. I use only Energizer Lithium for this, due to temp extremes. It gets direct sun in the morning and well below freezing temps at night during the winter. Each cell lasts about two years. There is a transmitter pulse every 20 or 30 seconds. The weight savings adds up with multi cell flashlights. Great video! A real bargain is the Panasonic Carbon Zinc AA. Very inexpensive, and they last longer than the cost might indicate.

overall, I would say the lithium battery is the best because it delivers a more consistent voltage throughout its lifetime. it sucks that they are so expensive though. this was an interesting video, I'd love to see something similar with rechargeable batteries, which is where I personally look for the best value proposition.

the only thing i could say that could be different would be to try each battery in each fan because we all know manufacturing is never consistant but that would also take over 60 hours so i understand the choice not to lol

These videos are really cool for so many different reasons

You should eliminate any fan/battery differences by rotating each fan with each battery after each fan had been broken in for a battery cycle. See if you get the same results. This was a great way to test the battery maximum output! Definitely revisit this

I literally did this as a 4th grade science fair project...this is sick. We concluded that normal (not extra strength) Duracell were the best, they did not last the longest, but had the best price/hour ratio. This is so cool to see more than 10 years later...good vid

Very interesting results for sure. I am a diabetic and use an insulin pump and I've tried many different brands of batteries and I've found that most batteries last 1 to 2 weeks the only one that always last longer is the energizer lithium last a whole month but when it dies it dies. Didn't know that the different types of loads would make that much of a difference in how long they lasted between them all.

Awesome video, I really like all the data and testing you provided. Is there a possibility you could test, some other brands up against your top 3 from here? Such as Home Depot, Rayovac and other brands?

Loved this video wish more people did this kinda stuff

Now leave fresh ones in the flashlights and check them every couple days to see which leaks and corrodes first

The lithium battery seems to be more for power. Like a 6 cylinder engine vs an 8 cylinder.

Great video really did some science on this one

I am so glad you're doing this I have always wondered the same thing

I'll bet the lithium AA had a higher voltage throughout the test resulting in a higher fan rpm. ( Motors rpm is directly tied to voltage) so it probably died sooner due to running faster during the test

You should publish the date codes of the batteries as well, if available. Batteries will self-discharge sitting on a shelf. I've had very bad luck with Amazon basic batteries for example. Maybe they have a better stock turnover and, therefore, are better charged when you receive them.

Great video. We use a lot of batteries so this is extremely helpful. Glad you showed up in my recommended videos. New subscriber.

Excellent tests. Good video Tyler. Thank you.

Love this because i have a 8 month old and everything basically takes batteries! I always buy Duracell , and they always die like within a week or so of him playing or his little sound machine at night.. I thought i was going crazy like how could the second best die so fast? Good thing a harbor freight is literally down the street and i will be buying a pack of the edge!!! Amazing content keep it up please!

I would like to see rechargeable batteries test like this.

I listen to/ watch you all the time now and definitely enjoy the scientific vids more. Love ur channel ❤

Like your videos, you have a great presence on screen, likeable, excellent ideas, a great work ethic and the giant subscriber base that goes with it. If you either hired or partnered with someone as a science/methodology consultant and an info graphics guy you could have one of the best test, hardware, fun entertainment channels out there. I would love to see you make that step and the growth and exposure that would go with it. Keep up the good work.

it depends on what youre using it for, lithium is best for high drain situations. which would be more powerful stuff. the fan was kinda wasting its potential is the best way to put it

From real world tests, I can say the Energizer Lithium is the best for electronics. Battery operated fans don’t have voltage or current regulation, so lithium batteries just dump everything into them, damaging the battery and resulting in shorter life, while regulated electronics can get a much longer life out of the lithium battery. Steady voltage output and steady current availability are also much better for digital equipment as opposed to analog. Low power analog devices might get a better result out of the Thunderbolt Edge batteries like your fan test showed.

I had walked past thunderbolt edge batteries numerous times, decided to buy one day when they were on sale. I am impressed 🔋

Why can't all videos be this informative and logical ? Good on you 🙂

Based on these findings, one can assume Energizer Lithium is for the heavy duty and Thunderbolt EDGE for stuff you want to last longer. Safe bet to see ENR stock price rise a little bit.

Interesting to know how different brand performs! Though the lithium batteries are intended for specific products so does not belong with these test objects.

Ran my own test on Energizer Lithium and Thunderbolt Edge batteries. Put them in a 512 Eotech, and the Edges can't keep up with the power demand. The Energizers stayed brighter longer, and last about 35 minutes more. Ran them both on the highest setting. If you need a consistent output I would just deal with the more expensive Energizer Lithium batteries. But for everyday items the edges are good.

Thanks Tyler, great video. The lithium batteries stand out in high discharge rate applications as well as extreme cold weather performance. Winter camping / survival groups use the lithium batteries for headlamps etc... In those applications these batteries will outperform many others, but in your typical everyday use case you are much better off saving the $$.

you should do this experiment again multiple times to get an average. also see if you can constantly measure fan speed. and make a graph of voltage drain and fan speed.

I wish you also tested some rechargeable batteries to see how they compare to non rechargeable.

Very useful test. Thank you. Maybe do another one for AAA !!!

Great job! Love how you tested in different ways. I will be picking up some Thunderbolt Edge batteries at Harbor freight.

I think the Energizer lithium made the fan spin faster maybe that's why it died so fast kinda like how Duracell optimum batteries work they can deliver longer battery OR increased performance like speed or torque ECT.

So I was hoping you'd do these tests to see if my purchase of the amazon basic batteries were worth it, I would say yes

Awesome video as always! You should test them in the love hammer. Wonder how much "nailing" time you could get!

13:15 as soon as you said the harbour freight was gonna win it slowed down 😂

Could maybe test the variance in a pack of batteries, see if some brands have more "duds" or ones that run out of juice noticeably faster

I've always preferred energizer and I also felt like they were better than all the other brands

Lol when editing you busted into the video I laughed my ass off. ❤

I've been buying the Thunderbolt EDGE batteries for a while now and they do seem really good. And at a very reasonable price.
