Overview: All Eneloop batteries 2005-2024

I’m looking at buying the latest Eneloop Pro AA cells at Amazon - which I believe are in the package labeled in the upper right: “Capacity min. 2500 mAH.” However, there are quite a few recent reviews saying that the measured capacity of many of the cells received by those customers is between 1800 and 2000 mAH. Most reviews don’t mention this, and they rate the cells highly, but several do. Are these cases in which people didn’t go through several charge cycles with their new cells, and judged their capacity too early? Or, should I worry about getting defective Pro’s that perform more like the basic Eneloop AA’s?

Maybe I should try the PowerOwl cells - that claim 2800 mAH and seem to have virtually all positive reviews recently? Anyone have any guidance they can give me? It’s been awhile since I’ve bought Eneloops - I have a few Pro AA’s from a few years ago, but I have not measured their capacity. I think it’s time to do that….

That’s what I came here for. Advice welcome. I need a couple dozen AA NiMH for new lights I want to be able to give away.

771

The best deal I found was at Ikea. The LADDA 900’s and 2450’s are known to be eneloop pro’s.

Took more than a week to get here. Their slow to ship.
The batteries I just received say “made in japan” on the wrapper.

772

I decided to buy Fujitsu 2000 mAH and 2550 mAH cells. They’re made at the same Twicell factory in Japan where Sanyo made Eneloop cells, before Sanyo was bought by Panasonic. So far, they seem to be holding up well.

773

From what I’ve read, Fujitsu’s seem to be identical to Eneloops. The other brands, not so much, but some are close.

774

That’s the conclusion I reached, as well.

775

ChibiM,
Can you tell me anything good or bad about the eight bay Panasonic charger for envelops? Thanks.

776

Hey 264, no, I can't unfortunately. I haven't really looked into them.

777

I will soon run out of alkaline batteries and would like to replace them with nimh or the like. Some of the nimh will be used in a marine environment. The Coast Guard and others entities warn against using lithium rechargeables in this environment. A closed boat in the sun can generate a lot of heat. I’ve never measured it but it can get quite hot inside. Question: Are nimh batteries any more or less susceptible to heat than the usual lithium’s? Are nimh any different about excess heat than alkalines? I’m trying to make things as safe as possible on the boat. Most marine recommendations are to use alkalines, though I wish to get those out of my routine as much as possible. Thank you.

Oops.. didn't notice this question, but I think I answered it, maybe on Facebook?

Been out of touch of NiMH chargers for a while but looking to get a portable one. Anyone know if the BQ-CC87 is indeed a smart charger? The product page shows an image of the box stating quick charger.

The little light attachment looks cool. Anyone know where to buy one? I couldn’t find any info on it.

Edit: In the description it says “Charging times shown in the table are only indicative and can vary depending on temperature and battery status” so I guess it is smart?

I also found a photo of the back showing output as 0.5A x 4 (AA) and 0.25A x 4 (AAA). Anyone know if those currents apply regardless of the number of cells? e.g. if populated with only one AAA will it be charged at 0.25A?

780

Good question, as far as I know this is a smart charger

781

Thanks ChibiM. Done a bit more research and does look it is smart in that current is varied “depending on temperature and battery status”. I’ve edited my post above.

I don’t really need another charger but the powerbank feature is interesting and looking to put all the Tones I’ve accumulated to good use.

782

Good stuff!

783

I have it.

It is totally smart.

But with old batteries (high internal resistance) it has a bit of problem.

When using as charger… It reports them as “batteries should be replaced”.(but it charges them… Other chargers simply refuse to charge them)

When using as powerbank… The output current is not 1Amp… More likely 500-700mA.

If you want full 1Amp output, you must use young/new batteries with low internal resistance.

With my old eneloop XX( with a few cycles) it shows that behaviour.

With my white eneloop (with many cycles) it works like a charm. No yellow led indicating batteries should be replaced and full 1Amp output

784

Ah good to hear! Shame to hear about the output but I guess I could just keep some new cells with me if I need to use it as a powerbank.

Did you look into the little flashlight attachment?

785

Based on the charging time table, it looks like those current values apply if you charge all 4 cells simultaneously. If you only charge 1-2 cells, charging times are cut in half, which would indicate that current is doubled, so a single AAA cell would be charged using 0.5A current.

786

What flashlight attachment? I am not seeing anything on that page, unless I missed it or my ad blocker got it.

Are you referring to something like this?

Hmm ok, makes sense. I’ll take another look through the manual.

Here’s the attachment which I mentioned and also ChibiM posted a few pages back.

There’s probably nothing special about it and a 3rd party USB light would probably be just as good or even better.

788

Any way to get that led light attachment? Can be purchased separately?

EDIT: the led usb light attachment is included only in japan version. Eu version dont include
