    Default Sanyo Eneloop MQHO3 Charger - Observed

    TheµMQHO3µ(NC-MQHO3-U) Super Quick charger appears to be a new offering from Sanyo which was first reported by RGB_LED.

    Outside of Asia, it's only been found bundled with a version of the Eneloop Family Pack offered exclusively by Costco Canada.

    It excludes the Eneloopy tester depicted in these images from thaicharger.com:



    The chargers shown in the fourth image are, respectively, the MQHO3, the MQRO2, and the MQRO3.

    The pack currently wholesales at Costco for *44.99 CAD, although it's occasionally subjected to an instant 10.00 manufacturer's discount.

    The pack originally bore Sanyo part number ECH422, and consisted of these components:

    1 - MQHO3 Charger
    2 - AA to C Adapters
    2 - AA to D Adapters
    4 - Eneloop AA Cells
    2 - Eneloop AAA Cells
    1 - Folding Travel Case

    The part number was subsequently revised to ECH4400, and the contents amended to these components:

    1 - MQHO3 Charger
    4 - Eneloop AA Cells
    4 - Eneloop AAA Cells
    1 - 12 volt DC Auto Adapter

    I believe the addition of the 12 volt DC auto adapter and two more AAA cells more than compensates for the loss of the two C and two D adapters. Especially considering the C and D adapters are commonly available elsewhere, whereas the auto adapter is not.

    After spending a few days with this charger, it's my opinion that it (and the trusty MQN05) should replace every other four place charger bundled with the Eneloop in North America.

    Here's why:

    Four fully independent AA and/or AAA charging channels.

    110-220 volt worldwide AC input (internal).

    Fold out two blade (North American) plug.

    12 volt DC input (including adapter).

    Pure white finish (very high gloss).

    Pale gray logo and lettering (matches the Eneloop).

    Very light, compact and sturdy (should travel well with plug adapters).

    A handy auxillary cell holder (presumed with some assurance).

    Recent build code LLM (which equates to 13 Dec 2007).

    The specifications:




    You will note from both its appearance and specifications, this charger could be purpose built for the Eneloop.

    Its output when charging AA cells is either 1000mA or 2000mA, which is exactly equivalent to .5C and 1C for the Eneloop AA cell. As well, its output when charging AAA cells is either 400mA or 800mA, which is again exactly equivalent to .5C and 1C for the Eneloop AAA cell.

    Based on my somewhat casual tests and observations, it appears capable of automatically recognizing and independently charging any combination of one to four Eneloop AA and/or AAA cells. It can charge one or two Eneloop AA and/or AAA cells at their respective 1C rates, and from one to four Eneloop AA and/or AAA cells at their respective .5C rates.

    If both inner positions are vacant, the outer positions will automatically charge one or two Eneloop AA and/or AAA cells at their respective 1C rates. If at least one inner position is occupied, all positions will automatically charge from one to four Eneloop AA and/or AAA cells at their respective .5C rates.

    The single green charge indicator located below the battery compartment will light when the charger is powered on, and remain lit until the charge properly terminates on all the cells in the charger.

    The charger also appears to apply what is probably a 'maintenance' charge following the primary charge cycle. As long as it remains powered on, it emits barely audible pulses that appear to correspond with the number and mix of cells in the charger.

    The instruction to place AA and/or AAA cells in the outer postions when charging only one or two appears to be just to emphasize the 'super quick' rate, and is not an operational restriction. You can instead choose to charge at .5C by simply placing at least one of the two cells in an inner position.

    However, the instructions to neither insert nor remove cells during the charging process should probably be complied with. It's just prudent to ensure the charger is properly re-set prior to commencing a charge, and thereafter not interfered with while charging.

    An image of the complete manual, in two parts, can be found here and here, and it is also hyperlinked to the upper and lower portions of the copy of the specifications.

    Finally, respecting its general performance, I found this charger terminates reliably, even when tricked with charged cells; charges to about the same capacity as the MQN05 and/or the MH-C9000 first edition, and seemed to leave my Eneloops comfortably below temperatures I would deem harmful.

    Overall, I consider this a solid offering from Sanyo, and even though I would really like to acquire one, the last thing I need is more of the Eneloops and adapters its bundled with. Accordingly, the one I'm using is borrowed, so if there's an observation or test you would still like me to take or to try, let me know as soon as possible.

    *Regrettably, some time after this post was authored, Costco Canada replaced the family pack containing the MQH03 charger with a significantly down-sized version containing the vastly inferior model MQH06 charger.

    They're somewhat lost in the first post, but here are the three things you will most probably want to know about operating the MQH03:

    If both inner positions are vacant, the outer positions will automatically charge one or two AA and/or AAA Eneloops at their respective 1C rates.

    If at least one inner position is occupied, all positions will automatically charge from one to four AA and/or AAA Eneloops at their respective .5C rates.

    The green LED will remain lit until the charge terminates on all the Eneloops inserted in the charger.

    I picked up this exact kit on June 17 and it was $31.99 + pst / gst = $36.15. Best deal that I could find as I didn't need the web deal that included 10AA's and 4AAA's and cost $59.99.
    Looking for: jhanko 'biohazard' V10R Ti clip, Luce de Notte (SS / Ti), SF Z2 (body, complete light, bored, unbored). Pls PM me with an offer.

    It appears that here has definitely been an increase Black Rose, but I still erred in my first post. I just verified that the price was actually 34.79 and not 34.99. That is sans taxes.

    Another indicator that the cost of the Eneloop is generally on the rise though.

    A heads up for anyone considering the Costco ECH422 pack, which is the only one currently known to contain the MQH03 charger.

    As noted in this post by gunga, the pack is also being sold with the Sanyo MQH01 (NC-MQH01U) charger. In fact, they have both been spotted in the same store, so you may even get to choose.

    My preference is for the MQH03, but as gunga and others have noted, the MQH01 also has its strengths.

    In furtherance of a side-by-side comparison, a two part image of the manual for the MQH03 can be found here and here, and the manual for the MQH01 can be downloaded here.

    I haven't been able to find a copy of the manual for the MQH03 in the .pdf format, so if anyone else has, please post its URL in this thread.

    On a related note, bob_ninja advised in this post that although his pack contained the MQH03 charger, it contained the manual for the MQH01, so it might be prudent to verify that your pack has the correct manual for whichever charger you choose before leaving the store.

    Thanks for the manual pics
    I am guessing that wrong manual is a systemic error and not just a one off.
    I wonder if anyone else bought it and found the wrong manual.
    In any case between 01 and 03 they are so similar that the old manual is still useful for those who are getting it for the 1st time.

    Interesting that the manul instructions are to insert batteries (step 2) BEFORE inserting into AC outlet (step 3).
    I always power a charger before inserting batteries.

    Regarding the heat comment, I certainly can feel some heat near end of a charge. I used non-Eneloops for a 1st trial run, around 2Ah I think.

    Where was the one you borrowed purchased at?

    The prices definitely have gone up, but not too much. Here in the Ottawa area, the 'Family Pack' with the NC-MQH03U now sells for $33.99 and the 6xAA/2xAAA packs have gone from $19.99 to $21.79.

    I have enough batteries and quality chargers, but may get one of these just for the quick charger and the adapters.

    I passed by the shelf again at Innes Costco in Ottawa. Be warned that there are 2 Family Packs, mixed!!!! One has the older xxx01 and another has newer xxxx03!!!! Make sure you get the new one.

    It was purchased in Calgary, and the price was definitely 34.79, which makes me wonder whether it's a simple pricing error or if Costco Canada engages in regional pricing.

    ...
    I have gotten into the opposite habit of inserting the cells before powering up my chargers.

    On my MH-C9000, it gives me time to make sure they are properly seated and then given a slight rotation to ensure the best possible contact.

    As well, in his informal review of the MQN05 charger, SilverFox encountered a delayed termination when he inserted an Eneloop while the charger was still powered up and charging other cells.

    Insofar as I am aware, this is the only termination problem ever reported for the MQN05, and the charger properly terminated its charge of the same cell when it was subsequently inserted before the charger was powered up.

    I'm going to presume your issue is differentiating between the two chargers reportedly bundled with the Sanyo ECH422 Family Pack, namely the MQH01 and the MQH03.

    The MQH01 is distinquished by an NiMH-NiCD switch on its face. It is also metallic silver in colour and has a single square LED below the battery compartment.

    Conversely, the MQH03 lacks any sort of switch. It is also pure white in colour with a single round LED below the battery compartment.

    Line drawings of both chargers are available in their respective manuals, which are hyperlinked in post 7.

    Here are some high quality images of the MQH03 compliments of Mr Happy and ThaiCharger:





    Please note that the 12volt DC adapter depicted in the third image is not included in the ECH422 pack,
    but its UL tag indicates it is a Kenic model no: KD-629B.

    The chargers depicted in the fourth image are, respectively, the MQH03, the MQR02, and the MQR03.

    Other than the ability to charge 4 AAAs, and the car cord capability, what is the advantage of this charger of the NC-MQH01U?

    I'm not aware of any significant differences other than those you've already noted gunga.

    However, the MQH03 does charge the Eneloop AA and AAA cell at their respective .5C and 1C rates exactly, whereas the MQH01 utilizes a slightly more aggressive rate.

    I don't believe the difference in charging rates is of any real consequence though, except as an indicator that the MQH03 appears to have been engineered with specific regard to the Eneloop.

    It also seems reasonable to presume that the MQH03 would incorporate updated technologies and, as importantly, take advantage of Sanyo's intimate knowledge of the Eneloop in developing both its charge and charge termination characteristics.

    I must also admit a bias towards the cleaner appearance of the MQH03, and the very fact that MQH01 has a NiCD-NiMH switch is fairly indicative that its engineering is getting dated.

    But then, if you happen to have some NiCD cells, that little switch gives the MQH01 a distinct advantage over the MQH03 ...

    I don't think the channels are fully independant. I think they are pairs chared parallel instead of series unlike most paired chargers. This is why you see the two different charge rates. This configuration allows single battery charging at the 2 amp rate or two batteries @ 1 amps.

    Not an uncommon configuration. Do not charge pairs with different discharge states. One will get over charged and the other undercharged.

    This was not the experience with the MQH03 that I own.

    According to Sanyo's instructions this charger does not charge at two different rates simultaneously unless AA and AAA are charged at the same time. AA cells would charge at 2 amps when only using outer bays and AAA would charge at 800ma while using the outer bays. If either or both of the other 2 inner bays are used then all cells will charge at their respective lower rates. (1amp and 800ma)

    When I first received my MQH03, it was tested with various battery configurations including mixing AA and AAA while using different bays to charge then discharged on the C9000 to test for capacity. During the charging none of the cells over heated and all cells tested in their average respective capacity ranges. It appeared to charge equally well when charging from one to four cells at a time with either the same or mixed size batteries.


    If the cells charged at different rates and terminated at the same time, it would show in the temperature of the cells and/or their capacity when discharged on the C9000

    If your MQH03 exhibits the characteristics you described then perhaps you have a faulty MQ03 and should contact Sanyo.

    The first post has been updated to reflect the revised package now offered by Costco Canada.

    Regrettably, there is still no indication that either Sanyo or Costco will be offering this charger in the USA.

    I did find it at the OnlineShop in Singapore, which does ship to the USA, but they're asking 42 USD for just the charger and two Eneloop AA cells:

    http://www.onlineshop.com.sg/index ... products_id=5204

    For those seeking extra assurance that this charger really does have fully independent charging channels, and is not simply charging in pairs with a parallel circuit as has been postulated in a earlier post:

    His name is Eneloopy, and he makes his home at eneloopy.com.

    http://www.eneloopy.com ... index_e.html

    I don't recall ever seeing it for sale officially, but some time ago it was offered as a promotional item with proof-of-purchase of certain Eneloop products.

    It has also been seen for sale on eBay.com on occasion, but nothing comes up at the moment:

    Sanyo actually makes an array of award winning Eneloop products. Regrettably, most are not readily available in North America. I believe this is the case with their Solar charger.

    For a look at some of the other items in what Sanyo has dubbed the Eneloop Universe, you can dig around this site:

    http://www.sanyo.co.jp/eneloop/lineup/index3.html

    The sites in Japan, so here's a hyperlink to Google translator:

    Does anyone know of any good on-line sites in Japan for buying things, especially ones that might ship to the US or other places? I believe there might be one or two people here who live in Japan, who perhaps could make recommendations. I have pottered around Amazon.co.jp, but have not got as far as the checkout to see what the delivery options might be.
