    I bought those packs from the one in Alhambra. I didn't see the Kirkland ones, but I wasn't looking for those (only eneloops), so they might have been there and I didn't see them. The Alhambra store is selling the 10-pack AA and 12-pack AAA eneloops for $19.99, so same price as Burbank.

    The 2 position AA wall charger is also good, comes with batteries, and is pretty cheap. My C9000 is usually doing some cycling or analysis so the USB and AC 2-position eneloop chargers actually get a lot of service from me.

    I thought the USB one would work well with a 7W USB-out solar panel. It did "work", but hadn't stopped blinking after a whole 10am-5pm day in pretty bright sun. One day I'll get out the power supply and 'scope and see what it does from marginal USB power. Off the computer, though, it's great. Runs cool, reliably terminates, couldn't really ask for better to go with 1AA flashlights.

    Just an FYI: Was at Costco in N. NJ (Clifton) today and picked up some Eneloops. They had packs of 10 AA or 12 AAA for $19.99. No charget included but with the 10 AA's you got 2 4 cell cases. These are the 1500x charge regular Eneloops.

    No signs of Kirklands or any other brands. Just the usual Duracell and Kirkland Alkalines.

    I only have the usb eneloop charger.
    It's a great little charger.

    This is the review that sold me on this little charger: http://www.stefanv.com/electronics/s...b_charger.html

    Excerpt:
    "The charger never draws more than 500mA from the USB port. It uses a very efficient power conversion circuit to convert the 5V DC input to a lower voltage at a higher current, much like a transformer can do with AC power.Charge termination appears to be done by detecting the voltage peak (rise and fall) that is characteristic of NiMH and NiCd batteries when they reach full charge."
    The brighter the light, the darker the shadow.

    I tried the 2nd gen here in Michigan and they started falling as they got colder.
    The XX eneloop work great to well below 0 F (-5c). I used them in o-F and they performed flawlessly!

    I also have a 9000 and i needed more charging bays so i purchased a 401fs and it is GREAT! Plus at 39$ and a life time warranty you can't beat it.
    With 4 AA in it (fast mode) the temps get to 87 F (31c). I am going to start another thread on this little charger and share my findings. Very interesting.

    That is why i purchased both and i declare the 401fs gives a more complete charge (in my tests at least). I think there is something to this neg flex pulse charging the FS uses WITH a life time warranty as well!

    There are already alot of reviews on that c401fs charger. In fast mode it overheats the cells way to much. A better choice instead of the maha c401fs would be the accumanager10 http://www.amazon.com/Accupower-Accu.../dp/B0017PR6B8 that does just aa and aaa cells that it includes a 12v cord with it. I have both and use my accumanager 10 all the time on my duraloop lsd nimh aa and aaa cells.

    I stand corrected. There are no rebranded Eneloops at Costco, only the genuine Sanyo ones. In the haze of looking at all the products, my mind scrambled things.

    Oddly enough, when I was at the Burbank Costco on Monday, they were completely out of the AAA Eneloop 12 pack, but there were plenty of the AA 10 packs.

    The last time I was at the Alhambra Costco, they were also out of the AAA eneloop 12-packs, but still had the AA 10-packs.

    Same here - local store only had the variety pack with charger - no AA packs or AAA packs by themselves.

    I ordered an 8 pack of AAAs from Amazon yesterday and got them this evening for $18 shipped I think.

    Finished "Refresh/Analyze" and "Break-in" using the Maha MH-C9000 battery charger on 20 Costco eneloops (AA) that were purchased Jan. 2012 in Southern California. The results are:

    #1 - 1864/1970
    #2 - 1862/1955
    #3 - 1896/1973
    #4 - 1914/1972
    #5 - 1911/2003
    #6 - 1857/1969
    #7 - 1848/1953
    #8 - 1850/1953
    #9 - 1864/1997
    #10 - 1856/1968
    #11 - 1873/1974
    #12 - 1839/1952
    #13 - 1821/1949
    #14 - 1798/1950
    #15 - 1885/2000
    #16 - 1846/1985
    #17 - 1836/1972
    #18 - 1818/1981
    #19 - 1822/1987
    #20 - 1841/1958

    Avg. Break-in = 1971.05

    I was hoping to see more in the 2000 range, so are these numbers normal for 1500 eneloops? I haven't seen many other people post their results. Maybe I should start an official thread to post refresh/analyze and break-in numbers for eneloops on the Maha MH-C9000.

    Sigh Re: The New Sanyo Eneloop Batteries From Costco

    Seems to be about normal...

    Here are another set from Battery Junction I bought at the end of Jan:

    Eneloop AA #9 2000 1000 500 1988 99.40% Refresh/Analyze
    Eneloop AA #10 2000 1000 500 1966 98.30% Refresh/Analyze
    Eneloop AA #11 2000 1000 500 1990 99.50% Refresh/Analyze
    Eneloop AA #12 2000 1000 500 1987 99.35% Refresh/Analyze

    Eneloop AA #15 2000 1000 500 2001 100.05% Refresh/Analyze


    My older Eneloops test around 1700-1900 mAh as well.

    I have used the XX"s in very cold (Michigan) and they perform great. I also don"t know about the others.

    I don't think the 1st generation Eneloops have any problem with freezing temperatures, either. They may not be rated for winter, but they've performed fine for me. I use them in an outdoor weather station, and it works fine down to -30C (or -22F for Americans). That's about as cold as it gets here in winter, so I have no idea if they'd work colder than that.

    However, it's very low-drain usage, so perhaps they'd struggle with a high-drain device.

    I've also used 1st-generation Eneloops in 3-watt LED flashlights in the very cold (perhaps -25C). That would be draining at about 0.6C, and flashlights still work. Probably won't get a long usage out of the battery at that temperature, but it still works for awhile.

    I've also used them in digital cameras (that take AAs), and they work in the winter. Again, they probably won't last as long as using them in the summer, but they still work.

    Totally agree! Mine has been flawless for years and charges Eneloops fine.
