2021 IKEA LADDA 1900 and 2450 AA Rechargeable Battery Testing and Analysis
HTML-код
- Опубликовано: 3 авг 2024
- It's here! This video features the capacity and internal resistance testing on the 2021 revision of the IKEA LADDA 1900 (1900 mAh) and 2450 (2450 mAh) AA battery. Internal resistance testing of the previous edition IKEA LADDA 2450 (2450 mAh) will be in a separate video. The LADDA 750 (750 mAh) and 900 (900 mAh) AAA battery testing will be in an upcoming video.
Dimensions of Batteries:
LADDA 1900 AA: 50.41 mm (L) x 14.28 mm (W) +/- 0.03 mm
LADDA 2450 AA: 50.41 mm (L) x 14.28 mm (W) +/- 0.03 mm
Note 1: Throughout the video, I call the new IKEA LADDA 1900 and 2450s "IKEA LADDA Grays" to hopefully minimize confusion.
Note 2: The internal impedance testing is still in beta, and there will likely be some changes in how the testing is performed. When that happens, I will post a new video with the revised and/or extended testing and link it in this video. For now, please use this internal impedance testing as a reference point between the batteries.

These are the best rechargeable batteries I have used. Made in Japan high quality. I use them in cameras, flashlights, GPS. two way radios and anywhere high drain/demand AA or AAA are needed, My son uses them in his X box remotes. I have made several trips back to Ikea to pick up more. Don't waste your time or money on anything else. Also thanks for all the work and testing. You gave us all the info in 20 minutes, but you invested a lot of time in this data.
I'm a Ladda fanboy too, I do think enloops are better, but the price of eneloops is crazy, LADDA is just such a fair price for what you get, decent NiMh batteries, I have them in all my AA and AAA flashlights, I even have a couple cheap 18650 flashlights running AAA LADDA in an adapter that makes three AAA fit a 1865l
Thanks for the testing, just found out about the new LADDAs today.
Thanks for covering the 1900s so thoroughly. When I went to my local IKEA store, that was the only stock available. They seem like a decent good deal. I’m now a new subscriber. And fan.
You are welcome! Thanks for watching!
Thanks for all the testing effort and especially the concluding remarks. 👍🏼
Thank you!
Thank you for your work! Very useful and please keep it up
Cells will discharge faster when it's cold, not when it's hot, since metals have a positive temperature coefficient, as opposed to semiconductors. This is why incandescent lightbulbs don't just burn out when you turn them on - they lead a lot of current the first few milliseconds before stabilising when it gets hot.
a great look! thorough testing!
if you should choose to take a look at the stenkol 0dV/dt charger, please look at whether it does trickle charge or not. any trickle charge current would be bad for these LSD cells and would mean you have to take them out of the charger asap after charging. diodegonewild already made a video but missed that. also it's a pulsed charger so you'd have to hook up the oscilloscope to the current shunt of the charger to find that out. my multimeter in series couldn't pick up any but maybe it's just too slow. also it terminates the charge much cooler than my BC700 (-dV/dt) so it should be better for the cells.
No one gonna talk about the nice pun he put in the thumbnail?
Well done! Smooth video and thank you for your research!!!
I'll go grab a few whenever I'll have a chance to. I want them for my Xbox controller. I guess I'll pick the higher capacity ones.
Should I care about the cycles?
Thanks again for the video!
I use the "standard capacity" batteries with higher cycle counts for low-power draw devices. Thanks for watching!
I've used eneloop pros, Fujitsu pros and ladda 2450s in my Xbox controller for years and have also tried the ladda1900s and standard eneloop. The pros/2450s definitely last longer. Don't worry about about charge cycles. They'll both last you for generations to come. 500 is a LOT of cycles.
Thanks for this.
The IKEA 2450 are the best rechargeable batteries on the planet even beating Panasonic not bad for a furniture company.
Just got myself a LADDA 2450 and the only one left here in my IKEA. All they have left were 1900s. When I heard they were Eneloop level in quality, I grabe a pack of em.
thanks for the review bro! SUBSCRIBED!
Much appreciated!
Thank you.
Great video! I wonder if you can comment on the confusing charge rate printed on the label near the seam...."Standard charge: 245 mA for 16 hrs."
Great video
Great video,and i decide to buy the new LADDAs.
Nice review. Thanks. In your opinion will 1900 mAh LADDA perform adequately in Omron blood pressure monitor or will it need 2450 mAh LADDA ?
Both should work fine. The 2450's might let you take more readings before needing a charge.
Is impedence variation between cells important? If a device is using 4 batteries and some cells are 40 while others are 90? Have you done anything with the Tenergy "premium Pro"? I assume these are probably identical to eneloop pros?
Hi, thanks for the video. I have the ikea 2450 is it ok to fast charge them in 2 hours on my Ansmann ma x-e speed charger 1400mA
Have you taken a look at the SkyRC MC3000 charger/discharger? It can be configured in many ways and get data on to the PC/Phone. It provides you with temperature, internal impedance, charts, etc.
That sounds cool. I'll take a look! Thanks for watching!
@@TheCuriousEngineerChannel bro get this charger, nothing even comes close to all the features and options you can change. I've had mine for years and still going strong. Make sure to check for new firmware if you get one.
Over a year ago(maybe even ~2 years) I charged 2xIKEA Ladda 2450, 1xGP ReCyko+ Pro(2000 mAh), 1x"Rechargeable"(no name battery from Auchan, 2500 mAh) - I just put a multimeter on all 4 and the Auchan one was at ~1.0V, GP ReCyko+ Pro at ~1.32V and the 2 LADDA batteries were at 1.3700V and 1.3706V which impressed me, one is how well these kept the charge but also how close the voltage is(I triple checked, every time the same voltage) after these discharged over 1 year - this made me curious about these batteries. These seem to keep the charge quite well.
My ISDT N8 charger shows these batteries have a 150 - 180 mOhms resistance while charging. To test resitance, should it be discharge rather than charging resistance?
was it not so that you can charge the 1900 type much more times then you can do the 2400 type ?
Very interesting video. I know nothing about batteries so pardon my potentially stupid question.
I had heard that while the 2450s have more capacity/etc than the 1900s they will passively drain quicker (i.e. a fully charged 2450 that is not in use will still slowly drain faster than a 1900 not in use) (which doesn't super make sense to me that they would passively drain at all but as I said I know nothing)
Is there any truth to that?
My goal is to get batteries that will last as long as possible, am I better off sticking with the 1900s or should i get some 2450s?
No they have the best drain of any batteries on the planet l.
If you just look at the percentage, then yes, the 2450s drain quicker. But even at 85% at one year, they are still higher than the 1900s 90% at one year.
2450 @ 1 year: 2082
1900 @ 1 year: 1710
I just bought 8 LADDAS. Do you recommend using ikea charger or third party? I have been able to find videos of good charger from you
Stenkol charger is very cheap but still good. Just a bit slow. Tested by @diodegonewild
Thanks 🙏
You’re welcome 😊
@@TheCuriousEngineerChannel 😁
1900s are almost the half price of 2450. Which one is more preferable to buy this case?
so whats better sir for 2450? the new one or old white ladda?
Same with different color
will you review the Stenkol Ikea Charger?
I've got a few others that I am testing at the moment, but it has been added to the list. Thanks for watching!
Wondering at what discharge current the cell manufacturer would use in order to get the stated Ah capacities on the wrappers. 100 ma or less ??
Who knows, but the IEC standard procedure for life cycle testing is pretty clear. The discharge rate set to go with the standard charge of 0.1C, usually printed on the label is 0.2C, so it all depends on the expected capacity.
@@SweDennis Thanks, so about a 5 hour discharge time.
Seems pretty agreed upon. Chargers with a break in cycle, such as the c9000 from maha default to that as well, so yeah. As to what manufacturers actually Do use however, wouldn't know, but 0.2C seems very consistent with what's on the label.
Capacitance dropping at lower discharge current is likely because they get not fully charged as charger cuts off too early.
I've found with that charger, that it actually slower to catch the -dv/dt at lower charge currents, and actually slightly overcharges the batteries slightly. So, if anything the capacitance should be higher.
which of the laddas should i consider to use in mouse for example? 1900 or 2450?
Both are great it’s just about the capacity, the biggest capacity normally the longer time you need to recharge it and the longer it will lasts but it won’t be a problem, in terms of the price I’d rather buy the 2450
@@theanalogguy1988 Mouse doesn't require high current, so using eneloop pro AKA ladda 2450 is totally pointless. They have far less charge/discharge cycles than 1900.
We use these all the time but one thing that nags me with the Ladda series is when they "cross out" in the charger (we have three Ikea chargers, two of the best and one simple). They seem to randomly just "x-out" in the chargers. Any idea why?
Shame that you never got an answer, what you had to do is buy a good quality charger.
A charger that is able to refresh and revive rechargeable batteries. Hope it helps.
@@TheLordstrider Thanks.
Would it be ok if i used my Panasonic Eneloop charger to charge these ? I don't have access to an Ikea charger.
Yes. Any solid Ni-MH charger will work fine to charge these batteries.
@@TheCuriousEngineerChannel thanks
is there a weight difference between the 1900ma and 2450ma ?
1900 mah 26 grams
2450 mah 30 grams
Hello, Could you help me for some question? Someone use your testing video tell other people that the Ikea Ladda 1900 is exactly same batteries as Eneloop ，is he right？ in my opinion ,you just say (their performance you have test） seems basically the same. am i right? if you can respond me,i will feel so happy，thank you. 😉
Hah. I did not. I mentioned that they are of similar performance. Thanks for watching!
@@TheCuriousEngineerChannel thanks！
For what it's worth I've read elsewhere that if it's an NiMH that's made in Japan then it must be an Eneloop as there's only one factory there that still makes them, the rest are made in China.
Considering the performance appears to be the same seems to support this theory.
I haven't seen the packaging on the new ones, not sure if they're still MIJ.
So the 2450 are superior vs the 1900 for hi demand situations? Can you give other examples beyodn say camera flashes ?
I found the 1900s don't work in a Wii remote, while the 2450s do. So, unless I was unlucky with a defective 1900, there's another example
@@AndrewBurrow-albcorp I presume it was a faulty 1900 cell.
Today I went to IKEA for the white ones and I saw that they are rebranded. The 1900 cost in Czech Republic just 4.5USD so I expected bad quality. But if they are like white eneloop, shut up and take my money 😀
Do they look similar to the 1900 LADDAs in this video? Thanks for watching!
@@TheCuriousEngineerChannel yes, probably the same. Thanks for video!
They are half the price of original Eneloop.. Its a deal!
I have IKEA 2450 mAh batteries and bought an Energizer Recharge 1 Hour Charger and I've just noticed that on the batteries the standard charge is 245 mAh for 16 hrs. So my question is that is it safe to charge these batteries with the Energizer Recharge 1 Hour Charger? Does really the charger charging the batteries for 1 hr and it does not destruct the batteries life cycle or something?
245 mAh is for dumb charger. Energizer 1 hour is smart. It will be safe.
The new green AA ladda batteries are rubbish. I'm not an electrical engineer but from day 1 buying the 'green' I noticed something was off about these. I'm a big fan of the old white label AA batteries but the green ones are a scam. I ended up buying an opus 3100 so I could charge and discharge these and compare to standard eneloop and the old white batteries. What I found was that they will charge to about 2450 which is supposed to be their rating but within about a week they've lost about 20-30% of their capacity compared to the eneloop and 'white' batteries. From my observation, with this loss they perform no better than standard eneloop which is 1900. I've tested this numerous times with the same result. I set the mode so first they discharge and then charge and then check the mah to make sure it's closed to the rated capacity. Then set them aside and measure the voltage over a week, then put them back in the charger to charge. Looking the mah that went into the battery at this stage, the capacity of the green batteries has dropped quite a bit. I get the same effect when I time these using in the same load like a flashlight. They perform no better than standard eneloops but not nearly as well in the old white label AA batteries.
There is such a massive price difference.. 2022 4* Eneloop Pro AA cost 16 Euros on Amazon in my country (EU) while very similar performing Duracell Rechargeable AA 2500 cost only 8 Euro.. And Ladda 8 Euros.. Yes the LADDA still say Made in Japan.. But Panasonic has also other batteries.. Evoltas.. 2450 and 1900 mAh.. good low discharge, but not as good as the Eneloop Pro.. Maybe the new Ladda are B products Evolta.. Personally discharge is not that important to me because the batteries I charge, I use often.. I have both the white ones and the new grey ones.. I will charge both and hoepfully test them in a few months..
1 week? Ok I will test that..
So, should I buy the new Ladda?
20:14 watch this part
So are the eneloops better than the Ikeas, but the Ikea are better bang for buck?
Much better bang for the buck.. It also depends on the use case.. If you use them for your Xbox controller, remote, LED candles.. IKEA
Jogging LED light.. That is where the extra quality might be worth it..
Ikea Ladda are Panasonic Eneloop with a different name on the outside, and half the price. But as someone else commented, they might also be from one of the other product lines Panasonic makes.
16:23 it was a LADDA testing?
You don't mention if there is any indication that the Ladda batteries are made in Japan or in China? Makes a big difference I think. Let us know and thanks for a very informative video!
They are made in Japan. He showed the packaging in the last video.
ИКЕА смеётся над нами.
Does anyone know how much in grams the Ikea AAA batteries weigh?😅
How about LADA cars? Are they any good?
I will only consider testing a LADA car that is powered by LADDA cells.
Good one! I thought of the car when I bought the LADDA cells! I both bought light gray AAs (1900mAh) and AAAs (750mAh) . I would like to see test results for the newer 900mAh AAAs.
lol bro these the same bats homie
