Ikea's Ladda is made with same specs and in the same factory as Eneloop pro! After Panasonic bought Eneloop from Sanyo, they moved normal Eneloop production to China, but pro-model is still made in Japan. I have about 300 Eneloops, but after finding out that Ladda is basicly same as Eneloop pro with 1/4 of the price, there is no competition! I have had 7 other brands in use, but they are all garbage in professional use. It's funny how the cheapest is also the best one.

[@MrV1NC3N7V3G4]

I use the Harbor Freight rechargeable batteries and they're great. The only drawback with rechargeable AA/AAA batteries is the lower nominal voltage. (1.3v vs. 1.6) On many devices, it doesn't matter, but some devices die quickly because the voltage drop is too low right from the start. This is especially true when using a device with 8 AA, where the voltage difference is 2 volts or so. For those devices I keep some highly rated Amazon alkalines on hand. Love your work brother.

Eneloop's advertised charge cycles have me torn between them and the Amazon Silvers. Not sure whether I should go for the cheaper option knowing I likely won't ever use more than 100 cycles, or pay a little more for the extra cycles and 'comfort' that provides.

[@tdogger73]

I haven't used the Amazon batteries but have been tempted to try them. I will say that I used to use the Energizer rechargeable batteries but got tired of them dying after maybe 20 charge cycles. This was over a decade ago, so maybe they are better now. I switched to Eneloops and haven't had a single one quit on me yet. I'll pay a bit more for that longevity assurance. That's one thing this test doesn't address, is how many cycles the batteries can take and what their capacities are after say 20 or 50 cycles.

[@RichardStefanits]

I have a double set of at least 7 years old of eneloops (2x4), and they still perform pretty good after some heavy use in Canon EOS system flash units. People say eneloop pros are even better but did not bother to test them, as these are still perfectly usable for my needs.

[@Quinid1]

@@ChuckoMountain-fv9yj you could have either purchased counterfeit versions of the white or you bought the black versions that are meant to be used in high demand devices that require frequent recharging. The old white eneloops do in fact have one of the lowest discharge rates in storage. It can be confirmed by the fact that certain IKEA and Energizer batteries that come from the same factory as the eneloops in Japan as there was only 1 factory in Japan that made these type of batteries. The quick way to protect yourself is to verify that they were made in Japan. Now things could have changed, but that was the general rule 10 years ago.

@@Quinid1 I purchased the white ones from amazon 5 years ago with an 8 position charger. They were too long when I got them, but forced them into the battery packs in flashlights. Both AA and AAA were like that. They said 2800/1100 on the outsides. Eventually the end discs fell off and brown stuff leaked. I threw it out. Their capacity markings arent truthful as verified by several on youtube channels. Now using LADDA brand no problems fit perfect.

[@Quinid1]

@@ChuckoMountain-fv9yj in that case, I am afraid that you ended up with counterfeit ones. They are counterfeited quite often. Even the LADDA started seeing counterfeit versions. The older IKEA LADDA and genuine white Eneloops are basically coming off the same assembly line. I have almost 100 eneloops and IKEA LADDAs accrued over the past 10 years. I have never experienced any leaking or even swelling. In fact I've yet to have any fail at all other than occasionally my aftermarket battery charger will reject a battery. Even then, the eneloop charger will recognize the reject and recharge it. My only complaint is that they do not make size D cells. The AA-D adapter is convenient, but it doesn't make up for the needed capacity.

Please rather than long storage Do Over nite 12 , 24 , 48 , 72 hour self discharge. We know what to expect from a battery that hasn't been cycled/recharged for a month or three. Its the over nite and charged a week ago that makes more sense for the average joe. If its 50% dead after a week while others hold up better. Thats something we need to know. Also multi drain recharge cycles. -> After say 25 charge discharge cycles how do they compare to each other. Who knows maybe it will surprise us.

They dont loose charge that quick, I run AAA Duracells in my headlamps to walk dog at night, if I change 4 tonight and throw back in charger tomorrow or even 2 days later to top off before I put them in, they usually only take 10-30mah to top them off at a 1.0A charge. I have a Xtar vc4 charger that tells u that info

Eneloops lose less than 20% of their charge when stored for a year, the japanese made ones that is, the present chinese manufactured eneloops might have different results.

I've been using AA and AAA NiMH batteries for years now. If a new device comes with Alkaline batteries, I throw them away. I haven't done any scientific testing, but my personal experience with three brands is Eneloop is way out in front of Eveready and Duracell. They all three work well to begin with, but only Eneloop has lasted for me in the long run. I've been disappointed by relatively few charge/discharge cycles that I've gotten from the other two brands. I primarily use them in remote controls and LED flashlights, and an AM/FM clock radio. I also have some NiMH in D cell size for larger LED lanterns. I make sure those are fully charged at the start of hurricane season.

[@ProjectFarm]

[@98dizzard]

Typically eneloop pro and higher capacity LSD batteries will have lower charge cycle ratings. The ones rated closer to 2000mah like the white eneloop will be better for multiple charge cycles. I was under the impression the Amazon batteries were just rebranded eneloops.

[@LitoGeorge]

Will you consider recycling those batteries instead of throwing away?

[@nawor3565]

Doesn't it make a lot more sense to use the disposable batteries first, then replace them with rechargeables? It seems like a total waste to throw out batteries that have already been made.

[@randomvideosn0where]

I have had Energizer and Duracell both for probably 10 years now. I'm sure the batteries have degraded but they still work fine for everything from headphones to flashlights and wireless mouse. My #1 loss of cells is from my mom borrowing them and throwing them out.

[@DavidDrivesElectric]

using mAh as a basis is only half the truth! The voltage level is very important! two batteries can have the same capacity in mAh but one can have a higher voltage which means you are getting more energy out of it. That's exactly where the Eneloops are doing extremely well! They keep a high voltage during high power load giving them the edge! That's why I switched to Eneloops in the first place. They might not last as long as some others but they perform much better in power delivery. Very important for flashes or power tools. It is also my experience that high capacity cells degrade fast. Eneloops last much longer.

[@MisterLepton]

You are correct sir. C/s * hrs = 60*coulombs or 60 times the number of coulombs (or electrons) available. But there’s a big difference between having 1 coulomb at 1V (volts = energy per coulomb or literally joules/C) and 1 coulomb at 50,000 V. One “battery” contains 1*1 = 1 joules of chemical potential energy while the other contains 1*50,000= 50,000 joules. And then of course the power you can output depends on both your max current & voltage (drop) at that current.

[@marchewitson6191]

Higher capacity usually means higher self drain, premium batteries at 2500mah are about the max for AA low self draining, if you intend to use the right after charging there are some really good 2900mah out there but won’t last if you store them, really depends on what you use them for.

[@cmuller1441]

The big question is "what do you mean by BEST". Many batteries have a higher capacity when new but that drops quite fast and after many cycles they are not better than eneloop or other "ready to use" batteries. I stopped buying the ones with the biggest figure years ago and the only one I have now are "ready to use" or eneloops, the previous ones were all down to 25% of the initial capacity and went in the recycle bin. I have not recycled a single battery since I stopped buying the ones with the biggest number on it.

[@ProjectFarm]

Great point. Thank you

[@JohnGodwin777]

“Best” depends on the application. Battery characteristics involve tradeoffs. Want super low self discharge? You don’t get super high capacity. Need the highest capacity possible for a wireless temperature sensor in your hot, filthy attic? Rechargeable isn’t the best option. Etc etc.

[@cmuller1441]

@@JohnGodwin777 I agree. For a all round nimh you don't need the highest value, however the test focused mostly on that factor, hence my comment.

[@cmuller1441]

@@ProjectFarm Thx. And Thx for your videos. One of the drawback of low self discharge batteries is that they have less initial capacity but also a little higher internal resistance so they don't like high currents: 1A is C/2 for a 2000mAh battery. Stopping at 1V is a bit high and you would get betters figures at 0.8V especially with high currents. Bellow 0.8V you get only a few more mAh and you start risking permanent damage. A little warning for people using the batteries in a device that put them in series (to get 3v, 4.5V, 6v. ..): recharge the batteries as soon as you see any sign of low charge. Don't push them to the limit. If one is slightly weaker than the others, it will be over discharged and could loose some capacity this way. I had that once on an eneloop. It lost 30% when it went to 0V. After a few charge/discharge cycles, some capacity came back but at the end of the day it lost 10% permanently.

[@mojojomo6750]

Agreed. I bought Eneloop and Varta batteries 6-7 years ago on Amazon, the latter having a significantly higher rated capacity. Within 6 months, the Varta's capacities had plumetted, within 2 years they were beyond use. The Eneloop AA's still retain close to their 1900mA capacities after many 100's of charges. One thing I found was that Eneloop AAA's, left on 'constant charge' in wireless headphones, tend to fail outright over time, as had happened to the batteries they came with. But I guess no battery likes being on a cheap unregulated charger for extended periods.

[@radiorexandy]

You should have charged/ discharged the batteries several more times, as most manufacturers claim that their batteries don't reach me capacity until several charge/discharge cycles; that is, they need to be "broken in". One of your respondents suggested charging non-rechargeable batteries. First of all, that is not possible. What you are actually doing is depolarizing the batteries and they are much more susceptible to leakage after doing so. Also, their capacity goes down with each attempt to "recharge" them.

[@skeezixmccat]

it's not ADVISABLE to recharge non rechargeable batteries, not impossible. Stick a dead alkaline in a charger for 10 minutes and it'll come back to life, if even only for a few minutes. I used to do it as a kid all the time for fun, they never blew up on me because I wasn't dumb enough to think that if I just left it in there while it got hot it would actually fully charge. I just did it to get another 15 minutes out of my gameboy.

[@noimagination99]

EVERY alkaline I have ever "recharged" has leaked at some point in the future, even just in storage. Don't do it! It barely even works in the first place, providing just a fraction of the original capacity.

having been a very heavy user of rechargeable batteries at one time using them in camera flashes for fill light in daytime. I found the eneloops the be very good and above all reliable. Most of the other brands I tried would shit themselves prematurely. With some bands I could get no more than 150 shots before 1 cell would just die and of course with no time to figure out which one was dead it was a case of swap all 4 out. I carried 8 sets of 4 to every shoot! When I got 2 sets of eneloops I found that they almost replaced all the others. To give you some idea of the workout these batteries got when batteries came out of the flash you could barely hold them in your hand as they were so hot. The eneloops handled this treatment day in day out with around 600 shots before they went flat. The other brands I had all rated at 2500ma would never get to 200 shots and often before that one of them would just die and could no longer be charged. Under really heavy use this test would be very different

[@zawaprz]

That's exactly what is my commentary ...while tester giving us numbers he does, does not mention factor of lasting ....for how many recharges?... so review is semi true story only to me, sorry. I have myself probably like around 50 to 60 pieces of AA of aEneloopes , and they are working for me like a charm. NOw, I have them 4 around 6-7 years and I think they were rated for 10 years ...

I'm disappointed with Eneloop, especially the 'Pro'; bought about 60 batteries, 4 years ago, mix of AA + AAA, PRO/normal, to use very occasionally in small LED lamps & fairy lights. 1 or 2 PRO from each pack would randomly die after 6-7 charges or start rusting [despite being kept dry /looked after]- the white variant has faired better, less deaths, but overall it's disappointing quality variance after paying more for what I thought was a top brand. I contacted Panasonic but obviously I can't prove how genuinely few times batteries have been re-charged before what I consider is an overly premature death, & Panasonic were uninterested, which I understand as they probably get people trying it on, but, meh; I need a better brand..

I've had no issues with Eneloop for low self-discharging. I can charge them on a Saturday and return to them the following weekend with no appreciable loss of energy. These past few years or so I use their Pro version; not the one you had tested. My only gripe with them is that their outer insulation is not as durable as I would like. It has a tendency to peel as a result of repeated insertion and removal from devices.

I will have to check out the Amazon Basics Silver batteries. However, I'm very much looking forward to your future video on the 3/6/9/12 month tests, because shelf life and number of recharge cycles play a HUGE role in rechargeables. Obviously, the more recharging potential a battery has, the better cost efficiency over time. That's why I use the Eneloop batteries. They may not have looked good in this test, but they are supposed to have the best shelf life, the least recharge memory, and be capable of the most recharge cycles of any other brand. Are those the latest generation of Eneloop's? I assume they are, but just checking. Also, there's additionally Eneloop Pro batteries, which have a significantly higher capacity. They just aren't rated to be as durable.

As a home inspector, I use rechargeable batteries constantly for my cameras (taking 300 - 600 pictures per inspection). I live in the hot desert of southern California and have noticed a marked difference in the cycle life of my rechargeable AA batteries. Conclusions from daily use is Energizer and Duracell NiMH batteries seem to last the longest with an average of about 1 year service life . Duracell takes the win for cycle life and average loss of power over a year of usage. Keep in mind this is in extreme 115 - 125 deg. F summer heat and being kept in a car/truck with no A/C running while not being used in my camera bag. I've clocked roofs I've inspected at 182 deg. F and attics at about 160+ deg. F.

The Ikea LADDA is much cheaper in my country. In fact a 4 pack of LADDA 2450' costs less than half of a 4 pack of eneloop pro 2500. and just about half of 4 a pack eneloop 1000's And some of the other well preforming batteries in this list are not available over here unless you import them yourself. (pointless: additional cost...) So I think what country you live in, and what deal your're able to get plays a big role too. If you're planning on more different battery tests, 18650's are interesting too. Specially the ridiculous Chinese Ultrafire ones with bull-crap 9800 Mah claims for example. but also ones that are supposed to be decent, like the Sony-Konion VTC6 (I use 4 3000mah VTC6 to vape, even though the ones i bought didn't come with a protection circuit and are meant to be used in packs only) I thing you're average AA or AAA or any common battery will pretty much preform near what the manufacturer tells you, some much better than others, but still. They''re not that dangerous, and not an awful lot will happen when you get it wrong. 18650's however, specially unprotected ones or ones with a massively exaggerated performance claim. If you get that wrong, they could very well go in to thermal runaway. I've gotten good experience with, Sony VTC6 and VTC5A, they seem to do very well even though I use my VTC6 cells without protection circuits. And here are some cells I've gotten for free with mods and flashlights over the years. I don't believe any of these could actually preform near their rated capacity.. Ultrafire 4000mah 6000mah and 9800mah. GTF 9800Mah If you look for them on amazon you'll find that some of them even have a bullshit story about theoretical capacity, rated capacity and actual capacity. because the seller obviously knows there's no way that's going to produce 9800Mah.

[@agriperma]

After watching this video and making a similar suggestion, another person commented that I should look at some of the other videos on test done, I did. after a few videos, you could find a trend on which ones are real and which ones are fake. Batteries with realistic claims, for example 1800 Mah were more often closer to actual capacity , than batteries that made outrageous claims which only had less than half that claimed by the real ones. Smooth tipped batteries seemed to always be fakes, the ones that were real all had the vented positive tips, without that plastic washer thing. of course , not having the flat /smooth tip does not guarantee its real. only that Weight. almost all the real ones weighed a lot more than the fakes. You have to be careful with refurbished real batteries, these are real batteries but have been pulled, and refurbished to look new. problem is , quality will be sporadic. Given the bad reputation that 18650 have, I have noticed a few sellers on ebay, display their own tests, and weights, of the batteries they sell, if I was to buy more, I would start with a seller like that.

Where did you find that the eneloop is rated at 2000? My eneloop says 1900 mAh and that's what I also find on the website. Considering this, the actual capacity would be much closer. Also, I feel like this test might be a bit skewed. I have the same charger as you do. I would suggest, if you didn't do so yet, to read the manual, as it's very good. For example, read up on battery forming. This makes the first few tests inaccurate, as you were measuring already when they were not formed properly. You didn't mention that you ran a "break-in" cycle before all of these tests. Should you have done that without mentioning it however, I would take my argument back. Also, since only the break-in mode measures the capacity according to IEC standards, I feel like so you can compare the capacity in a fair way to the one rated by the manufacturer you should only consider capacity values measured with this test. Good choice though on the batteries and charger! Personally, I would also have liked to see the 2000 mAh Ikea Ladda and the eneloop pros in the test. And I think also interesting would be a test running all of the batteries constantly in break-in mode for a month, to see how they perform after being in use.

I haven't tried all of these but I have tried most of the "bigger" brands. The thing about Eneloop is that they last forever. You can charge them up, not use them for six months, put them in something and turn it on and they'll work as if you charged them five minutes ago, then still give you the same number of charges they're originally rated for. (I think it's 1,000 for the kind you're testing.) I've still got the first Eneloops I ever bought back in 2010 or so and they still work. I've had other major brands that completely died when I used them that way after literally 10 or 20 recharges. In fact, I'd just about given up on rechargeable batteries until I found Eneloop. They just work how you'd expect a rechargeable battery to, whereas the others all seem to die prematurely. Not on one single use, but over some period of time or some number of charges.

Anyrhing bigger than aa is not useful. The only things that i know uses d cells still are some flash lights. And those flat square ones only in fire alarms. Other than that i don't really see any needs for making rechargable ones of these batteries. My bet is that theyre going to stop manufacturing the lesser batteries and just go for AAA as the master battery race.

You can get 3 Sunbeams at Dollar Tree for a buck. I'm fairly certain Duracell, Ikea Ladda , Amazon Silver, Fujitsu, and Eneloop Pro are all made at the Fujuitsi plant in Japan. I have read and seen a video that Fujitsu's plant in Japan makes the Eneloop Pro for Panasonic but makes the regular Eneloops at their Chinese plant. The Duracell, Ikea, Amazon silver, and Eneloop Pro are all very close in performance and rating on the label. I haven't been paying attention to the battery market since I found the the Sanyo Eneloop XX ( now Panasonic Eneloop Pro) I think I'll have to get an 8 pack of Amazon silvers for $17.99 instead of 4 Eneloop Pro for $19.99 👍 Thanks for the video, I clicked on visit advertiser.

[@LatitudeSky]

These batteries don't have "ratings" they have claimed capacity, which may or may not have any basis in reality. But there is no independent party doing any sort of rating. Just marketing people. Also, Eneloops from Amazon is risky. Amazon's problem with counterfeit goods are well known and Eneloops are well known for having fakes. With Amazon unable to police their merchandise, and such a big target, I'd really have to bite hard before trusting Amazon versus buying them from a reputable store with actual inventory control. With that in mind, I would not dismiss Eneloops just because some bought from Amazon didn't meet specs. I'd want to test some from a verified source, like Costco.

I appreciate that!

[@Eneloop101]

Let me say this first: Thank you for doing these kinds of testing! I know they take up a loooot of time, and I truly appreciate you taking the time to do these. However, I would like to point out a few things that you could improve on the next time to get a better picture of rechargeable batteries/ add a few very important aspects to this. If you ever would like to do another test of course ;) 1. First off, nobody is going to use a rechargeable battery for only 1 time. So instead of saying: you pay X for mAh.. You better say, you pay X for X recharges, or price per average mAh within X recharges. Then we are really comparing apples to apples. You can't take 1 recharge test and say this is the price you get for what you pay. ... Because most batteries loose capacity after several discharges. 2. Secondly you mixed up Rated Capacity and Minimum Capacity. The video says an eneloop is 2000mAh, and others you mentioned their minimum capacity. Please take a look at all your batteries and change the capacity to Minimum capacity. An Eneloop is 1900mAh, not 2000. So the numbers of the test results will be different I think. 3. As I mentioned in my first point, you have to take a battery life cycle into account.... so even without talking about prices it would be a fairer comparison to test how much capacity is left after 50 or 100 recharges. 4. How about looking at the quality of these cells overall. I know I sound like a nerd, and I am, but it is such an important aspect when you compare batteries. Take 4 batteries within 1 package and compare the capacity and internal resistance among them (this is a bit easier than to track the discharge curves, so I wouldnt bother most people with this) Do this after 5 recharges and 10 recharges etc, and compare them. I bet most of the batteries that come out on top will show a large difference in quality (capacity/internal resistance). What this means that when you use them in pairs or in a set of 4, some batteries get damaged/abused because of the lower capacity, and when you use the device till it's dead, 1 or more of these cells get overdischarged. And overdischarging rechargeable batteries is no good.. this only increases their internal resistance quicker and quicker, and are more likely to damage after several recharges. 5. I know you talked a bit about LSD, but this is such an important aspect with rechargeable batteries these days (since 2005 to be correct ;).Many people charge their batteries and use them 1 week later, or even 6 months later.. So reading/learning/teaching a bit more on LSD batteries would be helpful as well to inform all your viewers. Thanks again for the test! Apprecaite your time and devotion!!! I know it's not easy, and takes so much time! ChibiM from Eneloop101.com here :)

[@joedoakes8778]

Excellent points EL101.

[@ProjectFarm]

Hi ChibiM, Thank you for the comments and recommendations! 1. I realize you aren't employed by Eneloop and might not have any inside knowledge. However, it's worth asking since you follow the brand very closely and seem to have a great knowledge on the brand. Many viewers believe that competing brands, such as IKEA or the Amazon basics are rebranded Eneloops. Are there any NiMH batteries made by Eneloop that are being sold under a different name brand, such as IKEA, Amazon, etc.? 2. When it comes to the marketing approach used by Eneloop, there may be 100% truth in advertising but the other manufacturers make it much easier for the consumer to figure out the truth. The very front of the Eneloop packaging on the Eneloop package of four batteries I purchased indicated 2000 mAh, yet the industry standard for capacity isn't what's being marketed by Eneloop. The average consumer isn't likely to know that nearly all the other brands are advertise "minimum" mAh while Eneloop is marketing their product using a different standard than the competition. Consider reading all of the comments, and you'll see that many consumers interpreted the Eneloop battery as 2000 mAh batteries, not 1900. 3. Regarding LSD, that wasn't one of the test objectives for this video. That will be tested in several upcoming videos and 3 sets of batteries from each brand are "aging" now. I will likely test the batteries for self-discharge loss after 1 month, 6 months, and 1 year but that could change. 4. I'm currently testing battery cycles for all of the brands and will likely put together a video on that as well. Thanks again for the recommendations!

[@Eneloop101]

@@ProjectFarm Thanks for replying, and not taking my comments as an attack, but I hope you could explain a few things in the next video about minimum capacity.. That helps people understanding the difference. 1. You're correct, I don't work for Panasonic. I did however make a whole list of batteries that are "from Japan" you can check them out here: eneloop101.com/batteries/rewrapped-batteries/ 2. I'm a little bit surprised about that, since Eneloops on the Japanese market and European market only show Min. capacity. I would always refer to eneloops as 1900mAh, not 2000 :D On the battery sleeves you can see however they show 1900mAh. 3. Interesting. I did a discharge test last year of Eneloops that sat in their original package for 10 years and came out at 60% capacity. Here is the video: kzbin.info/www/bejne/q5PGoWuGfd-IsLs I also had someone commenting in the Eneloops thread on Candlepowerforums about 12.5 years old eneloops still having 60% of charge in them.. very impressive. I'm looking forward to your discharge test.. Remember than Eneloops lose their first 10% discharge the quickest.. and that is 1 thing Eneloop technicians try to figure out why that happens, and hopefully can get rid of that. 4. Awesome.. the more testing the merrier. And no, Eneloops don't always come out #1 in capacity, but standard Eneloops are hard to beat in many regard..... They keep on going.. and can have a beating! The Eneloop PRO are much more fragile... but still are very good performers. Thanks for taking the time to reply!

@@iancanuckistan2244 Most likely the ikeas start off as eneloop hopeful but during QC they're found to be slightly under their quality bars, so they're resold as laddas.

PF, you did not get a chance to test them with the rest of the brands so I want to make mention of the MAHA Energy PowerEX brand. I am the Field Equipment Coordinator for a small research firm in Alaska and have been using PowerEX NiMH batteries at work for over 15 years years. They were the first high quality rechargeable AA I found and have been durable and reliable. I have a couple of the MH C9000 diagnostic chargers and cycle the batteries through at least once / year. Your one test with the PowerEX that shows they run about 95% of their rated capacity is right on. They tend to hold that capacity as long as they are not damaged. The low-discharge rated batteries do well. I find they retain about 90% of their charge left after 6 months (my typical storage period). I appreciate your high quality videos. This one in particular is going to same me lots of money and time. Thanks!
