Overview: All Eneloop batteries 2005-2024

I’ve found that my 11 year old eneloops are mostly still well over 1900. Although mine did start out higher than advertised. Out of a batch of 16 I only had two at 1720 and 1767. Not bad at all. I used them mostly in my 2 x AA flash lights, my camping lantern and my hand held GPS. They have been constantly in use. My AAA’s of the same age have had very little use and they are still above the rating on the label. They have saved me lots of money over the years!

Exactly!

It's a little investment that pays back 100%!

I don’t know what the best deals on Eneloops are right now, but I’ve been ordering them from Horizon Battery on eBay. I just got some in the mail and they are still the made in Japan version, all 12 tested above 2000, most where 2050MaH or so. I have some of my 10, 11 and 12 year old ones that measure about the same. These batteries last a long time at rated capacity. I paid $24.95 last week for mine, looks like they are $28.79 now: Horizon Battery

I put four AA’s in service back in 2006 to power my handheld Garmin I mounted on my dual sport motorcycle, those batteries are still in use and still holding a full charge today. I keep two in the Garmin all the time and two are in reserve in the bike’s luggage. Those batteries have been cycled many times, I saved a lot of money using the Eneloops over alkyleaks. I started using these in 2006, those were my first set I bought. Haven’t thrown any away.

The two that are in the 1700’s I let get discharged for too long in my Fenix torch that I lost for a couple years or so. Found it under a car seat covered in dust stuck under the carpet partially, the batteries were very low. So those two were abused, the light was low on power when I lost it, but the batteries are still usable today in my computer mouse. Tough little suckers.

Tough little suckers.. That's an excellent conclusion.

I've seen horizon battery mentioned a couple of times. It looks like they are probably a trustable source to get them from. Do they ship worldwide?

They do appear to ship to many countries. On eBay I think its US only, but they have international shipping options on the website :Horizon Eneloops

The prices on eBay have been less in the past for US buyers, but right now the prices are a little lower on their website. Probably best for US buyers, they are located up in New Jersey.

I actually paid $24.76 for 12 AA’s during a sale on eBay. They are in packs of 4 wrapped in clear plastic. The prices went up last week, they are around $27 now with shipping. Still a good price for 12 Japanese batteries that will last for many years.

What charger do you test them in?

Those were put on a 4 slot LiitoKala Lii-500. I had it on the 700 mah setting.

Hmm… I’ve never tried testing my Eneloop capacity on Li-500. I guess I should try it. On my Opus, none of them go above 1900 mAh.

I just looked at the link for Horizon Battery. They have 800 mah AAA Eneloops for $10.15/4. They also have an Ansmann AAA for $9.79/4. They are rated for 1100 mah.

Any info on that Ansmann? Seems a bit excessive.

I don't know anything to say about the Ansmann, but you could start a new thread or look for HKJs tests.

If you gonna use them 1 by 1, you should probably be okay with the Ansmann. In series I dont know how reliable they are. Eneloops are usually the same in performance and only differ very minimally. While other brands tend to have a much greater difference between batteries, so one might have less capacity and be drained deeper during discharge than the other batteries. This will only get worse the more you use them together.

Not sure if I can ask here, since this is the Eneloop thread, but I have a question about FDK/Fujitsu LSD NiMh.

I saw in local stores of 2 kinds of FDK AAA NiMh — they look similar, but one is marked HR-4UTC(2B) while another is marked HR-4UTCEX(2B).
The difference is the HR-4UTC(2B) is in Japanese (and while I can’t read Japanese, I think the numbers seem to indicate 70% capacity remain after 10 years).
The HR-4UTCEX(2B) is in English (and the card box indicates “retains 70% after 5 years”).

So it would seem the HR-4UTC(2B) is better (10 years retain 70% vs 5 years for the other), although these could just be changes in markings.
Are they from the same generation (maybe just sourced from different markets)?

The former looks the newer version with the 10 years claim. If they both cost the same and if thats a reason for deciding, I would go with the newer ones.

chibim - I looked at the table you have published. It shows for the AAA a part number of BK-4MCC A/E for both a 5 year and 10 year version. How can the correct item be identified as the newer 10 year lifetime? I am not seeing a clear differentiator when trying to buy some.

Hi alternaty, you are correct. The product number is 4mcce or 4mcca (usa) both for the older and newer one. The only way you can see it, is by looking at the 10years vs 5 years claim.

Some sellers might not even now it, and leave the original specs and product pictures of the older version online.

Just make sure you can see they have the 70% after 10 years...which by now all major stores/online stores should have anyhow, because the newest eneloops already have been on the market for 3 years.

Take care.

I know this has probably been answered else where but couldn’t quite find the answer…

What CAN’T you use these batteries for??

Can we use them in ANY device that takes AA/AAA batteries???

They can be used in Most devices that take Alkaline batteries.

Especially in flashlights it's common to use rechargeable batteries.

Not all, there is a few low power device that requires the slightly higher voltage from unloaded alkaline.
