My mom briefly worked in a battery factory in her early 20s. Growing up we only ever bought the cheap brands bc she would constantly tell us her factory made them all and they just had different labels.

Something most people don’t know about Costco is they have very strict standards on what they sell. Products they sell have to be as good or better than name brand or they won’t sell them. Advertisement is what keeps most people buying name brand, when a lot of off brand stuff is as good or almost as good for a lot less. Videos like this prove it!

The only times I use name-brand products is when I need to make sure the battery is of good quality and won't risk exploding. For example, for the BIOS battery in a PC or laptop, I'd rather pay 2-3 times the price once every 5-10 years, than risk having the battery set the PC/laptop on fire.

People love to make fun of Kirkland, but Kirkland isn't a "brand" it's a "private label." Those batteries likely came off the exact same factory line with the only difference being the very last step - the label. Costco doesn't pay any money into advertising and retains what is basically the best quality assurance and testing teams and scientists in the industry using the money that they save. If it gets the "Kirkland" name on it, it's pretty easily the best or as close to (depending on partnerships) that there is in any category. Kirkland shampoo and conditioner, the exact formulation, in bottles often less than half the amount, can cost nearly $80 USD in some boutique shops. The Kirkland ones are like $10 USD. I worked for Costco for a few years, and basically buy everything from there if I can. It really is some secret weapon. What's funny is that people still poke fun or don't belive me outright. Some crazy negative stigma surrounds it, but Kirkland "brand" anything is basically the best in terms of manufacture quality, ingredient quality, and quality in testing.

FYI: Kirkland batteries are made by Duracell. The difference in charge is when you buy them and how long they've been sitting on the shelf waiting to be bought after manufacturing, they're exactly the same. They're a private label sitting on top of a brand manufacturer. Most things are like this, all store brands are just private labels made by a bigger brand.

yeah you really need to know what brand makes what because you could end up getting scalped by 5 times or more the price. The really good thing about having a name that you can trust is that if you're on holly day and really need to buy something that you know will work (in the long run) you should always go with the trusty name, if it's just a matter of a day or two, fuck it and save you money. That's usually the story for most consumable items, there's no point in over paying when there are some good brands out there, or rebrands of good brands. This is what I learned from my dad who works for a big chemical company, they will make one batch and sell 4-5 different "brands", the top clients ALWAYS buys the "Duracell" of their products because money is no question, but quality is always expected to be top notch, even though they must know it's basically the same thing, they just buy the "best" to be sure, I guess if anything goes wrong they can get compensated and state that they paid $5M for that last shipment and it ended up bad, so they are entitled to at least $5M+losses. But when it comes to hardware that's where you really need to be careful. you'll often pay just under half or 1/3 the price, but get 1/10 the life time.

I've had Kirkland double a batteries leak on several occasions but they're still the best bang for the buck.

I've switched pretty much exclusively to Eneloops or their equivalent NiMH cells as rechargeable batteries for things that use AA or AAA batteries. Duracell _USED_ to be good, but over the past 20 years or so have really fallen off a cliff reliability-wise. I don't know if it's the cost cutting bean counters in charge or changes in chemistry made due to environmental regulations (suspect some of each), but I've had more things damaged or destroyed by leaking Duracells (should call the damned things Corrodacells instead) in the past 15 or so years than I had ever had in my life before with all other batteries combined. I've seen them leak unused in their packaging while still several YEARS short of their 'use by' date. Then occasionally I'll get my hands on an old piece of equipment and open it to find stone dead but still non leaking Duracells from the 80s/90s. They've definitely gone to crap in my experience, and I won't buy them any more.

They were originally manufactured by Sanyo, and are now made by Panasonic. I've also recently gotten some made by Fujitsu; they too seem to work very well. They're not cheap, but in my opinion make up for it first by being reusable and more importantly based on the fact that so far, none of them have ever leaked and spewed forth corrosive nastiness to ruin my things. Unfortunately they don't make the Eneloops or Fujitsus in any forms other than AA and AAA; I wish they'd also make them in C and D cells, but for now have to be satisfied with the small ones. Definitely worth a look in my opinion if you use a lot of AA and/or AAA cells.

I've had past issues with rechargeable, particularly self discharge and uneven charge capacity even among the same batch. This causes the device to go dead long before the other batteries are 'dead', all it takes is one low capacity battery and there is very low run time. It is also unpredictable, one can't depend on gettign decent run time. This was helped quite a bit by low self discharge Nimh batteries and a quality charger that charges each battery individually. Those past issues still appear from time to time but are much less than it used to be and only in the past 2 years that I have found rechargeables actually practical (meaning dependable enough).

Have to disagree. The best part of this vid is that now that I've seen the pathetic attempt at "testing", I realize there is no scientific validity and thus do not have to watch any other "testing" by this channel. Such a waste of time.

Switched to Eneloops years ago and haven't regretted it. No worries about batteries leaking and its a simple swap and recharge when they die (because charged ones will hold a charge for YEARS without substantial self-discharge). Added bonus: no worries about disposing of dead single- use batteries properly (most people just throw them in the trash)

Engineer here: take a look at the data sheet. It has some useful information. You tested capacity at a low drain. But high drain devices might show different results. Also over temperature extremes. Voltage and ESR (series resistance) are both important. ESR is a value that predicts how much the voltage sag out under load. Low ESR means better for high drain devices.

Electronics designer here: It's not all about how long the battery lasts in use on ONE particular device, there are things like discharge curves (how long does the battery retain it's output voltage when it's discharged at DIFFERENT rates) and every device has different cut off voltage where they can't no longer work and every device discharges the battery at different amperage that can affect when one battery "dies" on you. And many high end batteries (obviously, not all reach what they claim, no matter the brand) have expiration dates that are well above cheaper ones. This means you can store them unused for much longer than cheap ones. Expensive ones can also be less susceptible to leaking over time or if you use them on a device that has very,. very low power requirements, they can very well outlast cheap batteries since they don't degrade over time as much even if their total energy stored might be less... So it's not as simple as you think.

I worked for a computer company and one of my clients was Duracell. The computer that I serviced was used to test the longevity of not only their batteries but other manufactures also in a variety of ways, on constantly, on then off like a flashlight... Over the years I have also learned that it depends on what device you put the batteries in. I had a small transistor radio (showing my age) that if I used Duracell batteries, they would not last half as long as some off-brand batteries, whereas in other devices, the off-brand wouldn't work very long and the Duracell was the overachiever.

I've read, and personally experienced, that Duracell are leaking in devices a lot more than they used to. I actually found this online when searching because I kept experiencing it. They have a higher priced line now, and some people think the regular line is now made to lower standards. I've lost a couple of keyboards and mice, a few flashlights (not cheap ones, either), and two sets of weather sensors to Duracell in the past 5 or so years. I've switched to high quality (based on videos like this) rechargeable, except in devices that say not to. Then I mostly use Energizer Lithium, which are expensive but have never done me wrong.

Mainline Duracell has been a major disappointment when it comes to leaking. It seems they are far more likely to leak than Energizer, Kirkland, or the Amazon branded batteries. It’s become so prevalent that lower use devices like my leveling lasar and such I remove the batteries after each use because clean up can be challenging and worst case the device could be junk. The one Duracell battery line that seems better is the Industrial line, I’ve had fewer leaking cells over a long period compared to the mainline batteries. I too have had good luck with the Energizer lithium’s but have found some devices don’t like them.

@Split your wig You should do that anyway to be honest. If I know a device is not used often I always take the batteries out regardless of the brand of battery. There are some batteries that will leak with use though. Those are the ones to watch out for. I learned the hard way when I bought a new TV and I used the cheapo batteries in the remote. It wasn't but a month later the remote started acting up. I figured the cheapo batteries finally died, but once I opened the compartment I saw that they had leaked pretty heavily. I used baking soda, water, and alcohol to clean it, but for a bit there I thought I lost the remote to my new television. I never use the cheapo batteries now.

I was lucky in that early on in my life, around the early to mid 90s I had a game boy and went through tons of AA batteries... I learned very quickly that the Kirkland batteries are just as good and often better than the big name brands. I always go for them now for the past 25 or so years haha.

Just buy eneloops once and save yourself a ton of time and money.

It was a great scientific test in my humble opinion. I never would have guessed the Costco batteries would be just as good as Duracell. I would love to see further research. How about testing EverReady's Energizer brand and Walmart's store brand. That would sum up about 90% of the market.

that’s interesting. the 20min difference in run time means that they’re practically the same... i’m curious to see what differences there would be with a more in-depth test than what this was. in my mind such a marginal difference could be due to multiple factors; were you sitting there watching it the entire time the laser was on, or did you leave the room and when you came back it had died? it was super late at night after all.

The sheer amount of AA batteries that I throw away weekly due to lasers on site has made be change all my lasers to built in rechargeable lasers, namely dewalt and milwaukee 12v. Might cost more initially but hopefully in the long run itll be cheaper, less inconvenient and better for the environment

Whereas Energiser needs to specify the ones that do well in electronics, since their O.F. would have 25% less total run-time when cycled the way some electronics do. However, the difference here is small as well. The differences in discharge rates, shelf life, draw tolerance, cycling tolerance, etc. lies almost exclusively in the difference in manufacturing processes, including quality control, since the basic chemistry is the same. From brand to brand.

I've had good luck with Energizer batteries , usually the Total amount of stored power (e.g. mAh) is probably the same as the cheap batteries, the more expensive battery will last longer for those slow-drain devices, or where the battery may sit idle for months at a time

One thing I noticed about Kirkland vs Duracell is that a few times the batteries leaked (my fault for leaving them in the flashlight too long). The leaked battery was always Kirkland, never Duracell. That’s my experience.

Keep trying. :-) You'll find out the Dura's will do the same. It's all garbage now. If you can, try to stick to NiMH, or use something with Li-Ion instead.

I used to only buy the Kirkland brand batteries but found they would leak and corrode in my devices quickly causing a mess. I had to locate and swap out all devices using them, also had to clean the battery compartments which was no fun. I stopped using them a couple years ago so not sure if they fixed that issue. I have not had that problem with the name brands.

I've had Duracell batteries leak and ruin a camera, a flash, a voltage tester, a moisture sensor and a flashlight over the years. And I've had many leak just sitting in my drawer unused.

Ironically it’s the opposite for me. I too live in the 416 and Duracell leak everywhere and were terrible. Kirkland I had no issue.

I have had that problem with many different types of batteries. I cured some of that in my less used devices by storing the batteries separate or in reversing the batteries in the compartments.

Yes they leak

That "I don't care" at the end is how I feel most days :)

What this video demonstrates is that Kirkland batteries are less than half the price per unit compared to Duracell and that Kirklands have a 1.7% higher runtime using a laser light source compared to the Duracell. The temperature was never taken into the equation, and the fact that Kirkland test started with the laser completly cold, while duracells started with a laser that was used for 16+ hours and then rested, and more importantly we don't know the manufacturing and expiring date of both batteries, because you know ... batteries self discharge when stored, that's the internal resistance coming into play. By the way I have never seen the Kirklands sold in 10 battery packs in my country, maybe the US have them.

It's pretty common knowledge that Duracell makes Kirkland AA's. The casing details are identical and unique to those two brands. I gave up on both because they both leak prematurely. They even leak in the package a few months after purchase and years before their expiration dates. I have had Eveready batteries go years beyond their expiration dates without leaking. Eveready's are all I use now.

Amazon Basics AA can dip a cent or two below Kirkland. I wonder how that stacks up. Also some store brands are made by other name brands. You can tell if you see only 2 options at a store, one name brand and the other store brand.

Duracell actually makes Kirkland batteries. It’s been confirmed all over the internet. No way of knowing if they are using the same quality materials and controls but it’s likely they are. Some people would be surprised how much your paying for advertising when you buy a name brand vs an equal quality no name brand.

☝️ what he said. In general most capacity tests show Duracell, Energizer and Rayovac neck & neck, with Duracell Quantum edging above the 3. But then there's batch to batch, manufacturing location and other anomalies that make it back and fourth. I grab the one that's closest to my hand.

I did some capacity testing on a bunch of AA batteries and never actually got around to Duracell but the carbon zinc batteries that say like super heavy duty have like 1/4 the capacity of alkaline and my advice is buy the cheapest alkaline you can find and that's probably the beast deal I didn't see a huge difference in alkaline

@r100curtaincall

That’s because the carbon zinc batteries are made for higher current draw. But they do come at the cost of a lower capacity, so they’re kind of a catch 22. That’s why they’re not really mainstream any more.

The heavy duty batteries has less capacity. But are designed for toy cars etc that runs shorter times at high load. The alkalines are way better for electric watches etc where you have a low load but for a very long time. The alkaline batteries also has less self-drain so you can store them for a longer time.

​@@james10739 Kinda sorta. They're cheaper, and they work better in short high-draw burst applications, and they work better in hot environments, as they don't degrade as fast under stress internally. For people who need to run things in short bursts but have a high draw, they tend to be better as they can deliver their full capacity. Alkalines lose a lot of their capacity as heat at higher draws for longer periods, but when they are run very lightly (like as a backup for a clock or something, they actually last quite a bit longer. There are definitely a lot more cases where the alkalines win out either way though now, especially as modern alkalines are far superior to old ones that were made back in the day when carbon zinc batteries were the norm. Especially in common everyday uses. They've gotten them down to a science now. You get similar contrasts from NiCd vs NiMH. NiCds have much lower capacity, but they also have far lower internal resistance and are very rugged to abuse and harsh temps, but NiMH are generally superior in capacity and most common uses, and are not as toxic, but they are also fragile and hate extreme temps. So there are a few rare cases where NiCd is actually still better, such as charging capacitor banks for flashlamps for example, or other high discharge systems where you need brief amounts of huge currents, like car starter packs, or AEDs. They also used to be used as ship or aircraft batteries for the longest time, and still are in cases for their ruggedness. They can be beneficial and more tolerant of the harsh discharges and environments and such, where as lithium is kind of a middle ground, with some of the best of both worlds. It's actually a common question I get at work sometimes, which is why I have an alkaline flashlight not a lithium one. I have rechargables for it as a work light, but as an emergency light it runs longer on alkalines than a lithium, and it gives me the luxury of replacing them at any time if the mains isn't handy to charge it. As with most things in life, the answer to what's best is 'it depends'. The lithium will run it for slightly longer at full brightness, but on alkalines on a lower brightness it will far outlast the lithiums several times over as D batteries have a far greater capacity per cell. (12Ah vs about 3 on the lithiums and the alkalines also keep longer.) You can really get into the weeds on this stuff if you really want to. it all depends on what you need as well as what you can afford. (edit: also, short circuit testing is poor testing methodology, and is dangerous. you shouldn't do that. it makes it impossible to compare things as all batteries behave differently. you need a constant load to be able to make comparisons, often at different draws. you'll find many batteries perform differently at different draws due to their specific properties) :)

First thanks for doing a nice video on this topic, and a good job at performing the test. I would say these 2 battery brands performed about the same. I find that in this test, the Kirkland only marginally out performed the Duracell but not significantly, as the Kirkland ran only about 1.7% longer. Please note that battery performance is also greatly affected by ambient temperature. It sounds like the Kirkland battery test ran from about 10:15 AM to 3:00 AM the next day, while the Duracell ran from about 4:00 AM to 8:30 PM. Also, though not stated, it was implied that the Kirkland test was performed in the house while the Duracell test was performed in the garage. So maybe the ambient temperature was was cooler for one test .vs. the other? By the way the Laser efficiency may also be affected by ambient temperature. So I would say these batteries performed about the same. That said, I would expect to get something for paying almost twice as much for the name-brand .vs. the store-brand. In this example we did not. Nice video ... Thanks P.s. "Killed the Carpenter!!!" sounds a little like Click Bait, no? I was expecting to see you hooked up to about a 30-thousand AA batteries (in series), grateful they were just cheap store-brand.

That's a great test. I want someone to do the same with other store brands like drug store labels, harbor freight, etc. to get a more complete picture.
