    In Europe, Varta markets the same cells as the Rayovac Hybrids.

    I first thought this was batteries because that is what the text says...
    Unfortunately it is adapters! Sorry! My fault! Come on Sanyo!

    I have 4 Eneloop 2000 mAh AA cells and 4 Ray-O-Vac Hybrid 2100 mAh cells that I exercised and capacity tested with the Maha C-9000. I'm going to let them sit a month and discharge test them. I'll then post the results. I'm sure Silverfox has a test going too, but I'm curious to find out how the Eneloops compare to the slightly higher capacity Hybrids in the self-discharge department.

    FWIW, the Eneloops measured around 1960 mAh, while the Hybrids measured around 2050 mAh in the initial testing.

    My question is-Is this the next best thing in nimh batteries? Are these going to replace the rechargeables I have now? Will standard nimh batteries be obsolete or do they and will they still have their place? I just bought four Eneloops at Fry's a couple of weeks ago and have relegated them to specific duties. Now I see this list and think they are not specialized batteries,but the next big thing for AA nimh users. I have a crapload of nimh AA's ranging from 1650 mah to 2500 mah and thought I was doing good until now! Do I need to replace them all or is low self discharge a compromise? Dang advances in technology!

    LSD vs NiMH(std.)/Alkaline

    AA and AAA cost about the same on most markets.
    A good price should be around €8-10/$10-12 for a 4-pack.

    I will not buy any more batteries of the classic NiMH type. From now and on it's LSD. Thanks to a higher voltage an Eneloop AA with 2000mAh should equal to ~2500 mAh and then you get the low self discharge on top of that.
    See www.eneloop.ca/eneloop_en_why.html#higher

    Example: Take a Powerex 2700 mAh and compare with Eneloop 2000 mAh. P2700 is one of the best high capacity cells but it has a self discharge of ~3%/day (80mAh) Eneloop has due to higher voltage a performance equal to a ~2500 mAh (manufac. data) and just a few mAh/day in self discharge.

    Given stated data and specs are fairly right we need to use our P2700 cell within the first ~4 days to get a higher output than E2000.
    In other words you have to plan your battery consumption in order to get more capacity with you in the pocket with for example a P2700. Remember that most classic NiMH cells has much less capacity than P2700!

    There are ~10 brands of LSD on the market today but unclear how many producers. Rayovac Hybrid and Varta Ready2Use are for example the same battery. Unfortunately there are no extensive tests comparing the LSD cells yet.


    My choice is Eneloop at the moment because they have great technical data and can be charged <1000 times. Sanyo is the biggest producer of rechargeable cells in the world and intend to replace all alkaline/std.NiMH with Eneloop. There are probably many "copy cats" (read stressed competitors) often Chinese that have to answer to Sanyo’s move. No one of the brands that claim 2100 mAh in capacity states which standard/norm they used when measuring the capacity. Some producers states only 500 cycles. Some of them states 2000 mAh as a shadow number which makes me believe that 2100 mAh is an extreme value that no or a few cells might reach in the best case. I believe they are a little behind in technology but that I can't prove!

    LRE, I agree with you, because I do not want a full time job charging batteries. However, I am going with the Rayovac Hybrids, because I can get them for $3.87 from Wal-mart with my $5.00 off coupons. I can not wait until someone does some independent testing, because manufacturers tend to use a little sales hype to get us to buy their brand.

    WHOA!! Thanks for the link! I was just going to post asking if and when Eneloop Cs and Ds were coming out.

    So now the questions are:
    1. Has anyone bought any yet?
    2. If so, what do you think of them?
    3. Where can I get some?

    The link (above in the original list - first post) for Panasonic 'R2 Technology', has expired. (No longer valid). "Site Not Found".

    Not so surprising, really. Panasonic makes the *worst* 'D'-cell adaptors I've ever seen. Thoroughly worthless junk. Rarely makes electrical contact with the AA cell within. Rarely meshes with outside contacts in various gear.

    I hope Sanyo follows through (on their eneloop website) with their promise of making their own brand of 'C' and 'D' cell adaptors available 'soon', because a gentleman in here - from Japan - mentioned that he *has* some genuine Eneloop adaptors, and they are of top notch quality.

    And THEN ........ (geeze)..... I just wish C and D eneloops (or any other LSD folks) would just start manufacturing low self discharge C and D cells *outright*, so that we could forget about the damned adaptors altogether!

    With regular C and D size NiMH cells available all over the place, there's just *no excuse* for the delay of these sizes in low-discharge format!

    --------------------
    *EDIT* - Wow! I really ought to pay closer attention to what is being written in here! (Immediate posts above). [blushing red]

    Am going to be hounding the web for more info on these D size eneloops!
    Gosh! It's enough to make one "EneLoopy", eh?

    The comparison is appreciated, wasBlinded. These two high-profile brands, in particular, seem to be causing the most interest - which of those two brands holds their charge the longest?

    On present info, I think eneloop (currently) wins.

    RayoVac Hybrid - after 6 months = 80% capacity; 70% after 1 year.
    Sanyo Eneloop - after 6 months = 90%+ capacity; 80% after 1 year.

    Of course, those numbers will be bounced around like a rubber ball in the upcoming year, as the LSD Wars begin! (about time too).

    (I think regular NiMH technology is in trouble) ;-)

    Amondo claims 80% retention after one year for the Titaniums, according to this page:
    http://www.amondotech.com/index.asp?...OD&ProdID=1131
    If true, this beats Rayovac and matches Eneloop but with a higher capacity (2100 vs. 2000). However, I'm skeptical since the Titanium cells have the same capacity as the Rayovac, have similar appearance (esp. at the terminals), and thus seem to be made by the same manufacturer. Anyone have more information about this?

    >>> I have a short answer and long answer.

    The short answer is "no". The long answer will take a while to put my thought together to post. Will do this when I have time.

    The market ratio between AA and all C and cells combine is like
    99.99:0.01

    Yes, it is that dramatic!

    Any chance of 9V Enduros? I would think there would be a decent market here since 9V primaries are expensive and lots of things such as smoke alarms and multimeters still use 9V batteries.

    I figured market demand would be the reason... after all, the C & D cell NiMHs that are generally available from Energizer are essentially repackaged AAs.
    I had to ask though

    I'm another who would jump right into NiMH LSD Cs and Ds. I use a lot of C and D NiCads now and I could go on using them for quite a while but they have been marked for oblivion by the Green Nazis in spite of the fact that there is no alternative available that does what NiCad Cs and Ds can do. They still work better than NiMH cells in radios and other non-light electronic applications and they have increased efficacy in portable lighting now that the Crees and Seouls are on the scene.

    I've already switched over to Eneloop AAs and AAAs and have bought my last NiCad in those sizes. I truly wish someone would market LSD NiMH cells in C and D sizes to fill my needs but I'll bet I'll be buying another bunch of NiCad Cs and Ds from Amondo. Oh well, they'll last forever.
