Has anyone tried to charge eneloops 1500 times say within a year or 2

If you charged at 2A and discharged at 1A constantly, that's around 3 hours for a cycle. Multiply that by 1500 and that's 4500 hours so half a year of constant cycling at sort of real world charge/discharge rates.

Ok has been settled. I am going to place an order for the Eneloops 1800 the link i was provided. Hopefully these cells are the real ones as there seem to be a lot of counterfeit when buying batteries.

Would like to thank you guys for providing such information :)

For AA eneloops here the following info to see what generation batteries they are:

HR-3UTG = 1st gen =1000cycles


HR-3UTGA = 2nd gen =1500cycles

HR-3UTGB = 3rd gen = 1800cycles

BK-3MCC = 4th gen= 2100cycles

Whoa..what??

Doing a Google search reveals that the 4th generation were released in April 2013 and are indeed rated for 2,100 cycles.

There's also a 3rd generation XX but it's still rated for only 500 cycles and with the same capacity as before, so I'm not sure what has changed. In addition, there is now a 2nd generation Eneloop Lite that is rated for 5,000 cycles!

4th generation probably not released in US yet, they seem to release the new stuff for the Japanese market first, then the rest of the world a couple months later. Not like you can get Eneloops anywhere but online :(

Costco that i know of carry Eneloops, but only if you have their "elite membership club card" or you won't be able to buy anything.

If you want to know more about the different Eneloop editions , please search Google for "all eneloop batteries", and it`s about the 3rd hit,
there you can find my very informative thread about all existing eneloop batteries.
I gathered all the info in the last few years.

I'm wondering if there is a mistake on the table. The LITE 2nd gen AAA are rated at 950 mAh and the AA cells are rated at 550 mAh?

Eneloop Reference Table removed per ChibiM's request.

See post #29 for further reference.

Looks like both the AA & AAA data are switched wrong.
Should be the other way.
AA 950
AAA 550
See 1st gen and numbers match up with Min. values.

I own a bunch of the "green" evoltas (purchased about 3-4 years ago), and they are regular NiMH. Mine are rated at 2000 mAh for an AA cell, and are good for 1,800 cycles. The "orange" evoltas are rated at only about 1000 mAh for an AA cell, but are good for 2,100 cycles.

This new "black" evolta, however, appears to be a new Low Self Discharge (LSD) cell from Panasonic. (To my knowledge, none of the other evolta batteries are LSD -- Mine certainly aren't. But, perhaps Panasonic plans to switch them all over to LSD?)

It seems that all NiMH EVOLTA are Low Self Discharge.

I am actually looking for non-LSD NiMH. I wish to find something of high life span like the new 5000x Eneloop. The low capacity of 1000mAh is OK.

I feel that in my audio amps, my Eneloop AA and AAA do not sound energetic as non-LSD NiMH. My theory is that the LSD also makes them slow in normal discharge, that when the device needs a pulse increase in current supply, there is a slight delay.

I know that in constant current discharge, Eneloop is capable of high current. Maybe someone can do a test on pulse discharge to look at the pulse shapes at different frequencies.

...It seems that all NiMH EVOLTA are Low Self Discharge...[excerpted]

That's interesting. Mine certainly aren't. But, if you have found that to be true, then Panasonic must have switched them all over to LSD (fairly recently?). I do most of my shopping on the internet, but the next time I am in Tokyo, I will try to remember to check out the "battery store" and ask someone what is going on.

By the way, and I kind of hate to even mention this, because I seem to spend so much time posting about the "black" Eneloop Pro batteries, that some people probably think I must own stock in them.

But... You might want to "look into them." They are the "Least LSD" of all Eneloops, and I believe I read someone saying that they might be capable of greater current output. I don't know whether or not that is true, and how they would perform in a "pulse" situation. But, it may be worth looking into them.

Another audio enthusiast here.

I would disagree, I suspect in double-blind testing (yes a bad word for audiophiles) you would find no difference. The Eneloops are known for low output resistance, as evidenced by high performance with larger current draws. Eneloops are not "slow". If they were, on flashlight reviews with higher frequency PWM you would see significant rounding of the pulsing pattern.

Not to mention, in most power supplies for an audio amp there is a capacitor section which is much more responsible for the quick transients required by dynamic music.

The only advantage I would see to non-LSD is potentially higher capacity.

If your 1800x Evolta is not LSD, then that is most interesting. That means regular NiMH can be as robust as Eneloop.

I don't need the extra capacity. Actually I prefer the more robust 5000x new Eneloop Lite, if I want LSD. I don't want to worry about one cell going bad after half a year or so. The 500x life span makes that much more likely to happen than the 5000x of Eneloop Lite.

But if all consumer NiMH switch to LSD, then I do want the least LSD of Eneloop Pro.

There are industrial non-LSD NiMH AA that are of much lower capacity, e.g, 1500mAh. Those are hopefully more robust than consumer ones around 2500mAh. But I don't know where I can buy some 1500mAh at retail quantity.

should I be concerned with getting 1500x batteries in an 1800x package? I bought two 4-packs of eneloop AA and AAA from amazon: http://www.amazon.com/gp/product/B004UG41W8/?tag=cpf0b6-20

the packaging in that picture says "1500x/3years" (which was fine with me, I didn't know there was an 1800x). what I received though was the exact same blue/green packaging as that but with "1800x/5 years" on the front. however using this link all the batteries inside are 1500x: http://www.eneloop.info/eneloop-products/faqs/faqs-eneloop.html

all my batteries have HR-3/4UTGA and no line under the crown (the eneloop faq and this forum say 1800x have HR-3/4UTGB and a line).

the date markings of my batteries are "13 05" and "13 03" so they would seem to be new enough physically to be 1800x but aren't.

I'm not concerned with the extra 300 cycles so much but rather if mine might be counterfeits? iow having the wrong battery in the most attractive packaging? or just a factory screwup where they put new/fresh 1500x batteries into 1800x packaging? that didn't seem too likely to me since it would had to have happened with both AA and AAA products plus over a few months' time (given my batteries date markings).

Hi Mdixon, please post some pics..
so we can see if there are some possible fakes...(which I don`t think they are)

But HR 3UTGA are 2nd generation eneloops, with 1500 rated cycles.
and HR 3UTGB are 3rd generation eneloops, with 1800 rated cycles.

Why the codes on your HR 3UTGA with 1500 cycles is still a question.. Have heard that more before, but have no answer to it.
If you want to know more about the different eneloops available, please take a look at THIS eneloop overview thread.

mostly it's a question if the wrong batteries in the wrong package means anything. the same thing occurred with the AAA package I have but I only included scans of the AA stuff.

so it's for two different product lines, over at least a 2-month period (based on the date stamps of the AA and AAA batteries in them) - wouldn't a factory mistake be more confined, caught and corrected quickly? since it wasn't it makes me wonder. using the pictures on this board and elsewhere from everything I can determine the batteries are genuine but since this is the first time I've bought eneloop I wouldn't bet on it.

notice the package is the same as the 1500x/3 yrs package but on the left says 1800/5 yrs. I also included a scan of two of the 1500x batteries from it:
