    Default Is Sanyo Eneloop a Good AA?

    Hello,
    I am new to the forum but have been reading alot of threads on the site.Because of the information on this site I just purchased 2 Fenix flashlights.(LD20,and PD30) I would like some help in determining a good quality AA rechargable battery. I am going to buy the AW RCR123A for the PD30 So any help with the AA would be great.
    Thanks in advanced for your advice.

    You will get all positive replys and cannot go wrong with the Eneloop. I think I have about 50.

    Your question should really be about where to find the best deal on them

    Yes.

    The Eneloops are currently the best of breed in the LSD NiMh category.

    Hey Guys,
    Is there a website you would recommed to buy the Sanyo Eneloop and the AW RCR123A. I aready looked at 4Sevens.

    Lighthound also sells AW RCR123s.

    Thomas Distributing sells the Eneloops at a decent price.
    You can also get them at Costco.

    I don't think there are any "one stop shopping" sites that sell Eneloops and AWs cells.

    I use these on my Graphing calculator as well as my radios and they last alot longer then my other standard nihm rechargeables.

    Yes...really.

    Here are some criteria that can be used to judge NiMH cells:

    1. Self-discharge -- how long will they hold a charge after charging?
    2. Consistency -- what is the variation between samples?
    3. Quality control -- how likely are you to find a dud?
    4. Durability -- how many charge cycles can you get without loss of performance?
    5. Robustness -- how much deliberate or accidental abuse can they take without failure?
    6. Power delivery -- how well does the voltage and capacity hold up under heavy loads?
    7. Capacity -- how much energy can they store?

    When judged under all these categories taken together, Eneloops are possibly the best NiMH cells on the market today, bar none.

    If you have an HH Gregg store nearby, they have them. A 4ack of AA is $8.61 with tax (7.75%).

    You did notice those links did you?
    Eneloops are not on top of those charts, so why eneloops are better than GP ReCyko for example?
    You do have some comparison charts etc, not just a gut feeling, right?

    You may add to the list
    8. Availability
    9. Price

    Mr. Happy's list is good, but the battery of choice depends on the weight factor you assign to each category.

    Assuming each category is equal - Eneloop will probably win.
    If you place more weight on "Capacity" and "Power Delivery" and less in other categories - a different battery may win.

    Eneloop just happens to be the most tested & readily available battery on this board - thus all the raving about it. Really, the only limitation of Eneloop is capacity.

    Many of us have tested both Eneloops and other cells. When it comes to long term testing, Eneloops always seem to rise to the top. Charts like the ones you linked to don't always tell the whole story.

    I don't know that Eneloops are the most readily available. Often they are hard to find in shops and have to be ordered on line, but I think finding them is worth it.

    GP ReCyko vs. Sanyo Eneloop comparison based on links&charts in this thread.

    1. Self-discharge =ReCyko
    2. Consistency =Eneloop (not enough Recyko data available)
    3. Quality control =Eneloop (not enough Recyko data available)
    4. Durability =Eneloop (not enough Recyko data available)
    5. Robustness =Eneloop (not enough Recyko data available)
    6. Power delivery =ReCyko
    7. Capacity =Recyko
    8. Availability =post&packing is like 2$ so who cares?
    9. Price =if I want the best, do I care?


    So the winner is Eneloop.
    Riiight.

    Correction to power delivery, under heavy load Eneloop wins, at 2A there is no big difference.



    I guess with Fenix LD20 there is no difference between Sanyo, GP and even with Medion LSD cells?
    Not to mention how important the charger is.

    Default Re: Is Sanyo Eneloop a Good AA?

    If you have a decent charger or a battery tester - Get ReCyko and independently verify the findings. I am doing the same for Eneloop vs Sanyo 2700 just be cause I am tired of hearing "Regular NiMH will discharge in few days". Hopefully several other people will do the same test to have a decent sample base.

    Egsise, I see you're new here, in that case, welcome to CPF!

    May I just remind you that there's no need for sarcasm or any impoliteness when debating topics. It adds nothing to the arguments presented. CPF is a family friendly forum, and has a policy against trollish behaviour.

    I have sanyo batteries from 1999 that are still in use today so when another brand has been out there for 10 years and still going than I might consider them, until then sany is still tops for me.

    Yes you may remind, but..

    Me? Trolling?! IMPOLITE?!

    Now now, I had links and charts, and I even corrected myself when I studied the charts and found that I was wrong.

    Some others just had a gut feeling and no any data to back their claims, now isn't that trolling?

    If people just believe "facts" blindly and don't question them, sun would still be revolving around the earth.

    Sorry for possible spamming/flooding/trolling and my bad english, this isn't my native language.

    There are only 2 maybe 3 factories that make LSD type cells. Sanyo in Japan and one or two factories in China.

    All Japanese LSD cells are made by Sanyo and relabled. In which case just by the cheapest or easiest to aquire. There is quite a bit of indication that the Japan versions are better than the Chinese versions after a bit of use. There are a couple hundred threads on eneloop vs XX do a search.

    As far as "the best" Nimh. That will always be an endless debate because different people put different emphasis on the 9 categories above. But yes Eneloops are very, very good batteries.

    How did you come to this conclusion?

    Perhaps if you do a search as suggested, you can find out the facts before slinging accusations toward established respected members. You never know, you might find out they actually know what they are talking about.

    Unforgiven:
    A new member can be treated like led lenser by older members?
    You noticed that I had linked charts etc. in my posts, right? Those charts were saying that Eneloops had not the best capacity, or lowest self discharge rate.(I did use search, did I)
    So why not tell us all the reason why eneloops are still better even if the figures may say otherwise?

    You know the answer, I know the answer(now,I guess), but does Mr.AdhdIwantanswerandIcantreadthesethreadsforweeks understand why Eneloops are the best LSD cells?

    And pls, this time no answers without explanation, that does not help anyone.

    Egsise: there is an accumulated history among the members of this forum in using various makes and types of NiMH cell. This history includes use in real applications over a period of time, with many charge cycles, different charging regimes, in different devices, at high and low temperatures, and spanning various other variables and circumstances.

    It is difficult to condense all this history down into a few posts or charts, and it is difficult for a limited number of laboratory tests to give the complete picture of how a given cell performs.

    So by all means look at the charts for information, as we all do. But also consider that others have bought these cells and really put them through their paces, and that experience might be worth noting.

    To give you one example, SilverFox took the time to put some Eneloops and other cells through over 100 charges on a 15 minute charger to see how they stood up to it. He discovered (as I recall) that the Eneloops were still at 100% capacity after 100 cycles (this thread). There is also an interesting note starting at post 129 of that thread, comparing Eneloop durability with Rayovac Hybrids.

    Since it appears that links to highly regarded members tests and word of mouth from members that actually use the cells is not sufficient, the only other recourse is for anyone having issues with that information is to purchase cells of the various brands that are of interest, perform tests on them, and find the ones that work best for their chosen usage.

    SilverFox is this sites resident battery guru and expects a lot from his cells.
    If his word is not good enough, no one elses will be.

    Hi, I'm new to the forum, but after reading here I decided to buy the Sanyo Eneloops. I also wanted a charger that would do it all and be able to travel. So I bought a Lacross BC-900 charger which seems like the one to buy and it can handle 110-240 as well.
    So far I couldn't be happier with the Eneloops and have them in a lot of my AA powered Wiimotes and flashlights as well as TV remotes etc...
    I will probably buy another dozen of them after Christmas. Lots of Great advice in this Forum!

    Wow, Eg. I take you to be Mr.Adhd...s, so I will try to be succinct.

    It seems to me no one flamed you. You are being too quick to counterpunch.

    Here's some knowledge:

    1) You can count on seasoned, accurate information from Silverfox or Mr. Happy. Both have strong technical backgrounds and skill. They have helped many, and won a lot of arguments (typically friendly on their part).

    2) They and others after long discussions have argued (in more reflective tones than here) regarding why the Eneloops deserve first consideration in all but a few scenarios. Such as the need for that last 26% of capacity that the current highest claimants are (hopefully) providing. If you have to have it, and don't mind giving up the proven reliability, charge latitude, and ability to provide a lot of current with relatively good drop in Voltage - then by all means get the latest Sanyo.

    3) Sanyo has been a leader in AA batteries of all types for a long time. Their products are private labeled by big name suppliers. Their 2,700 mAh high capacity is a good battery, and the 2,000 mAh Eneloops are widely acclaimed.

    4) I'd rather not debate, so if you want any further exchange with me on the matter, do not disparage.

    Welcome, Tiff.

    I got my first Eneloops about a year ago. Mine have all worked great, and I've given them to friends who used lots of batteries. The little 4 cell Sanyo chargers are pretty good units for the cost and convenient form factor. I have some similar applications, but mostly my Fenix 1xAA and 1xAAA lights, where they perform well.
