I just did some quick historical Amazon price looking on Amazon for the 10 and 16 packs of AA and AAA Eneloops on camelcamelcamel. As far as I can see, these 10 packs are the best price for these batteries in years.
They havent been that low in several years. Ive had deal alerts setup for 2 years. This is about as cheap as Ive seen the last 1+ years. Even checking Keepa and CamelX3 show this.
As an alternative, the Ikea Laddas are supposedly rebadged Eneloop Pros at well under $2/battery. Ive been running those and have been happy with the results.
Because those 2500mAh batteries were garbage, with an insane self-discharge rate. With NiMH, the higher you go in capacity (at the same size), the higher the self-discharge rate and the lower the overall lifespan. If you want high capacity, the Eneloop Pros are 2600mAh, but they won't hold up as well as these.



People put way too much stock in the whole "made in Japan" thing. Not all batteries made in Japan are good, nor are all batteries made in China bad.

You are correct that the Energizer NiMH are usually made in Japan, however they are definitely not rebranded Eneloops. They have different physical and electrical characteristics. Strangely, there's a huge difference between the 2000mAh and 2300mAh version. The 2300mAh version are garbage, while the 2000mAh seem fairly decent.

I know people often bring up the supposedly rebranded Eneloops, such as the IKEA Ladda or Watson MX/CX but I'm not convinced they're as good as genuine Eneloops. The ones I've tested have been quite inconsistent, unlike real Eneloops, which have all performed virtually identically. Also, a site that did long term testing had rebranded Eneloops at the bottom of the chart, while the genuine ones did quite well.

Just a heads up on these nickel batteries.
They are 1.2v, which is under the normal spec of 1.5v (non rechargeable or rechargeable ion batteries)
All my AA batteries are rechargeable, and I recently stopped getting anything 1.2v because random toys for the kids just wont power up or run unstable with the lower voltage batteries, so lithium ion rechargeable are worth it for me in this case.

Panasonic Eneloops are all made in Japan and many professional and YouTube tests show them to be superior in many ways including longevity and reliability.
We've got some that have to be pushing 10 years old.
I'm sure there's degradation, but they still work and we just toss them back on the charger a bit sooner.

How do you even tell if it is counterfeit or not?

You'll know. They don't hold a charge. I got some counterfeit ones and contacted eneloop, they said I voided the warranty because I used a non eneloop charger! I was very pissed off. I was using a nice powerex charger too

The 1.2v is the only drag. I have too many finicky devices that look for 1.5v. if anyone is looking, they are starting to make usb-c rechargable 1.5v AAs

Agree. I bought rechargeable usbc 1.5v batteries from Aliexpress. Been using them over a year, very stable.

Quote from CharlesBarkley :
$5 to ship, I don't live near one either, but they are more capacity (basically the same as Eneloop pro for the price of regular Eneloops)
...at the cost of higher self discharge, like the Eneloop Pros - which is what makes these (non-pro) Eneloops attractive.
It's not fun to grab a 'charged' NiMH only to realize it basically fully discharged itself since the last time you charged it.

I haven't had that problem with the higher capacity cells, but everyone's experience is different.

What's your use case? Remotes? Wireless kb/mouse?

Wife just bought several floating candles (see: Harry Potter) and the set uses 20 AAA. So far, I've only had to use one set, but I can see this getting expensive.
I use in Xbox remotes, toy RC cars, wireless mouse, other kid toys, etc. Pretty much anything needing a battery. Im sure they would work great for floating candles.

Powerowl is a better and lower cost battery.
PowerOwl did do well in Project Farms video recently; it was for lithium non rechargeable batteries however.

Funny, we had the same idea on the floating candles. That's how I came across posting this deal.

I had just bought some Powerowl rechargeables as well as some EBL Year of the Snake batteries. We have a Slytherin in the house and they wanted to put the Snake batteries in these candles and we will have a fun battle of the houses to see who wins. (Ravenclaw are PowerOWLs, Gryffindors are the brave Eneloops)

"Better" based on what, exactly? Project Farm's latest video? Those were their non rechargable lithium ions he showed...

Man he really goofed up that segment by transitioning directly from the 5-6 yr NiMH test followup right into the comparison chart for NON-RECHARGABLE lithium vs alkaline.

Quote from stockshowgypsy :
Those are cycle ratings from manufacturers. I get close to that using good chargers. Old Powerex 9000 for break in. SkyRc 2600 and 3000 for recharging and Opus 3100 for top offs. Charging parameters are Bluetooth controlled. Refreshes are performed when necessary. 150/600 cycles are about right for low quality chargers.
The numbers are based on different IEC testing methodologies. The lower number is based on the newer revision. Most companies (including Panasonic) still plaster the numbers from the old method on the front of the package. The lower numbers, if advertised at all, are hidden in the fine print. For these Eneloops, you can see it in the picture of the back of the package.

While there are circumstances where people may get close to these numbers, the average person (even with the best charger) isn't going to come remotely close.

Quote from enesugur :
I agree. Although Ladda and others from Japan are not a bad batteries, they are not comparable to Eneloops
ProjectFarm recently did a comparison of rechargeable batteries used for 6 years @17:05.
https://youtu.be/efDTP5SEdlo?si=Pu7xkPl9ksZqkit-
The Project Farm videos are interesting and informative but I do have some issues with his methodology.

Here [aacycler.com] is a site that has done some long term testing. I find the high capacity AA results interesting. The Panasonic Eneloop Pros rank 7 out of 39. The Japanese IKEA Ladda, Duracell Ultra, and Fujitsu Black are in 35th, 36th, and 37th place. They only beat the Panasonic 2700mAh (which I don't know the origin of) and Energizer 2300mAh (which I too have found to be awful).

Quote from lukem5 :
wow thats remarkable for 13 yo batteries, what is the mah capacity on the 2007 batteries? im amazed they still work
I have some Rayovac Hybrid 2100mAh from 2007 that are still going. They Rayovac Hybrid/Platinum are the best NiMH I've used. It's a shame they don't make them anymore.

Quote from SharpLake2934 :
Is that why you can't find the Gen 5 eneloop in US?
Don't quote me on this but I vaguely recall seeing evidence of a few people getting them.

Quote from redpoint5 :
I prefer Powerowl over Eneloops, but then again I haven't tried Panasonic recently, so maybe they've gotten better.

They may be cheaper but both Powerowl and EBL massively overinflate the ratings of their NiMH batteries. Just look at the user reviews of those who actually tested them. I haven't personally tested any Powerowls but I did test the 2500mAh EBLs and they're closer to 1850mAh.

Quote from tdwpgtp :
If people are correct that they are just rebranded, they are probably the batteries that didn't meet the more stringent quality requirements to get the full eneloop branding. I doubt Panasonic throws out batteries that still perform fine, but not as well as their flagship. Rather they rebrand or resell them
I suspect this is the case. However, evidence and my own experience suggests some of them are really low quality. Out of the dozens of batteries I've tested, one Watson CX (rebranded regular Eneloop) was the only cell that arrived totally discharged (0.9V).

Ikea LADDAs are $10 for a 4 pack; this equates to the same price as the Eneloops, but with a higher mAh rating at 2450. They are also highly rated and tested well on Project Farm.

I haven't tested one of those super old ones, but like someone else commented they are Sanyo branded not Panasonic, Once I get a chance to dig one out of the kids toys I will test them.
