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.

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.

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.

Quote from MWink :
Those 500/2100 cycle ratings are based on an outdated, completely unrealistic standard. The massively lower rating based on the newer methodology still seems overly optimistic to me. I think those are around 150/600 cycles. The Tenergy Premium Pro are the highest capacity I've tested, though they come in closer to 2700mAh. That said, I'd take Eneloops over them any day.
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.

check project farm battery testing, the knockoffs work fine for the most part. all battery chemistry will degrade with time, eneloops no exception. these are a ripoff IMO - ofc if you still buy alkalines that is far far more of a ripoff.

I switched to rechargeable Lithium Ion AA for my door lock and they work so much better than these. They also charge faster via usb-c.
There is no 1.2 or 1.5V Li-ion batteries. Li-ion cells typically have 3.7V. Those "batteries" are Li-ion cell + dc-dc converter + charger. Might be OK for stuff that doesn't require high currents (remote, candle) but you should NOT rely on cheap & ultra small form factor dc-dc converter for suppling high currents.

This video from Project Farm has some good info on rechargeables towards the end of it.

I have eneloops I bought from 2012 that I still use. Back when they were Sanyo branded.
Some of them are starting to need replacement after moderate use over the years. For reference, in 2012 I paid $40 for a case with 12 aa's and 4 aaa's with charger and c and d adapters. Turns out we use the aaa's more than the aa's and 10 aaa's for $20 seems pretty good to me. At $25 for 10 aa's and $20 for 10 aaa's, both are good prices imho 🙂👍
I mainly use them in motion sensor lights in the hallway and kitchen. I have a number of other popular brands of nimh's, but the old eneloops always seem to outlast the Amazon, rayovac or energizers I've tried.
I just hope the quality is still there. With any luck these new ones will make it 12 years as well.

If you also check project farm's latest video, the eneloops were one of the only brands to virtually lose no charge capacity after over 300 cycles in his lights.

I personally have owned eneloops since I worked at Circuit City back in the day, like 2007/2008 and they are still working today.

I have a set from 2012 that I just tested on my charger and they tested at 1951mah- 2011mah. I would call that excellent long term durability.

Because of enleoops, I haven't purchased an alkaline battery in like a decade and a half. I have 1 eneloop leak in a device that I had to throw away, but otherwise I trust them without any concerns on super expensive stuff like my Gearwrench E torque wrenches.

I did try some of the supposed eneloop clone AmazonBasics rechargeables and they didn't last very long before their capacity had dipped below 80% total capacity

I also think people should be realistic about Japanese versus Chinese batteries. Yes, eneloops made in Japan are the gold standard. No doubt about that.

However, it's been years since eneloops have gone for $2/battery meanwhile I think I've gotten Amazon Chinese ones for $1 or less on sale. For the purposes of flashlights, remotes, Xbox controllers, the Chinese batteries do fine.

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.

Are they? I thought some were made in Japan and some in China now, so you have to be careful when buying. I may be misremembering but I thought there was some change in ownership of the battery production line that drove this. Actually came here to ask how you can tell if these are the good ones or not.
I believe they're still all made in Japan. The Amazon product description for these batteries says:

"QUALITY YOU CAN TRUST: These eneloop rechargeable AA batteries are made in Japan and packaged in the United States"

Picked up a two each of these and the AAA packs last night to stock up. Best price for both they've had for a while and it feels like it would only get worse post tariffs.
