Universal Fast Charger with USB charge function
Charges AAA, AA, C, D & 9V rechargeable NiMH and NiCD batteries
LED status display
LCD display shows charging and conditioning status of each rechargeable battery
Automatic full-charge detection and termination
Automatic discharging - regeneration

Charging currents

AA approx. 1000mA
AAA approx. 500mA
C/D approx. 1000mA
9V approx. 70mA

Charging times

Battery size Capacity(mAh) Charging time (h)
AAA 150-900 0.42-2.5
AA 600-2500 0.84-3.5
C/D 1000-4500 1.4-6.3
9V 100-200 2.0-4.0

Full-charge detection according to "Minus Delta U"
Delta is used in mathematics to designate differences. "Minus Delta U" denotes a negative voltage difference in this case.

If a battery is charged with a constant current,its voltage steadily rises. Once a battery is full, however, its voltage reaches a maximum and drops slightly with continued current flow. This slight voltage drop is detected by the charging electronics and charging is terminated.

    Is this a good option for aa & aaa eneloops? Is the charging slow enough?

    • King Tightarse on 05/07/2014 - 21:48

      Current with the AA's is the same as the default setting on the Maha C9000, so that is fine, but it really comes down to the method of charge termination IE how effectively does it detect the delta V dip. Does it have any back up termination methods such as a set ultimate voltage and/or some kind of heat detection shut off? Thats where the cooking happens.

          It comes down to how effectively the voltage dip is detected. Plenty of so-called smart chargers fail to detect the miniscule voltage drop and fly right past it, cooking the batteries nicely.
          Back up methods such as a set ultimate terminal voltage and heat detection are necessary.

        • mranderson978 on 07/07/2014 - 10:16

          @King Tightarse: Got a multimeter handy?

      • slowmo on 05/07/2014 - 23:24

        @KT: I have the C9000 as well, am actually charging my AAs @ 400m as per 0.2C calculation (based on C=2000mha) by the documentation. The default is 1000mha I believe. Wouldn't that be bad for the battery if you used default?

        • King Tightarse on 06/07/2014 - 00:16
          +2

          No I dont think so.
          If you are using Eneloops they are notoriousy rugged and forgiving but there are two things that will kill them. Overcharging and reversing polarity (usually when in series where one battery flattens first and is reverse charged by the other)
          The reason 1000mA is used by the Maha is because it induces a good solid delta V dip that can be reliably detected. Anything less than C.3 is more difficult so 700mA is as low as you would probably want to go.

        • davidl2 on 06/07/2014 - 21:06

          @King Tightarse:

          I usually use 1/3 of the battery capacity for Maha C9000
          so for a 2000mA eneloop, around 700mA or 800mA

        • slowmo on 07/07/2014 - 12:19

          @King Tightarse: ok thanks, will try. I still charging my 2007 eneloops with 400mA so it's hard to tell if there's any detrimental issues. It was used to power my speedlite and now my led torches.

    • g12345567 on 05/07/2014 - 23:16

      Had a similar one and it was also very slow. Ended up replacing it with this Activ Energy charger which I picked up on clearance at Aldi a while back for $5.50. Have no complaints with it at all.

    can get it a little cheaper from aliexpress I think you can ''make offer'' of about $21.98 if you decide to go aliexpress make sure you get version 2 very important

    • hollykryten on 05/07/2014 - 23:16

      What about the Watts Clever smart battery charger is it any good?. It's $28.49 delivered. It says charging alkaline batteries but it's also for NiMH batteries. I also saw it at Jaycar the other day for $50.

        • hollykryten on 05/07/2014 - 23:23

        • krisspy on 06/07/2014 - 12:29

          @hollykryten: the i2/4s are basically the best "budget" chargers until you step into lacrosse/Maha price range. Itll charge nimh and li-ions aswell

          @rokoz: Thanks. I was a bit concerned as some of the feedback said shipping from HK.

    • [Deactivated] on 06/07/2014 - 16:20

      I have the original i4 and it's rubbish, I can't imagine v2 is better. When they advertise v2 is made of fire resistant materials it makes me nervous that either version will 'charge til it burns'

      Does this aldi model have 4 separate charging channels or does it charge in pairs (not 'professional' quality)
      Also the 9v battery charging function wouldn't work on the true 9v rechargeables? Only on 7-8v ones (not 'professional' quality either)

      • davidl2 on 06/07/2014 - 21:02

        I was at Aldi & one of the packaging was opened, and the manual inside says it charge 1-6 batteries
        should be separate channel?

    • cheongk on 06/07/2014 - 20:53

      Guys,
      If you are using the i4, remember to charge a minimum of 2 cells at a time. According to the user manual, the current may be too high if charging a single cell.

      Nitecore strongly recommends that AAA, AAAA and 10440 Li-ion
      batteries are not charged alone in the i4 charger. When using only one
      charging slot, the i4's current automatically sets to 750mA, which
      exceeds the maximum current range of most AAA, AAAA and 10440
      Li-ion batteries. Failing to follow to this recommendation can result in
      excess heat, battery damage or even explosion,causing property damage
      and/or personal injury.

    • krisspy on 06/07/2014 - 12:29

      Crappy. They usually charge too fast for the battery.

    • frewer on 06/07/2014 - 13:48

      You can have my Energizer, just paid the delivery fees and i will send it over. Serious.

    • Russ on 06/07/2014 - 17:59

      In general, avoid buying battery chargers from people who want you to buy more batteries from them. There are a few exceptions, but the vast majority of such chargers will kill your batteries - but not so quickly that you throw the charger out immediately.

      Compare with companies like LaCrosse and Maha - their chargers are more expensive than generic chargers, so what could they offer you that you would want to buy one instead of a generic charger? In this case, it's quality.

      However, there is a place for generic chargers. If you only have a handful of rechargeable batteries, you don't really need to spend a lot of money on a charger. Use the money you saved on the charger to buy new rechargeable batteries every year or two.

      But if you depend on getting maximum capacity and life from your batteries, a good charger is essential.

      • afterabargain on 06/07/2014 - 23:06

        Had a look at the 2 chargers mentioned. Whats your opinion which one is a better charger and maybe future proofed somewhat.

        or

        http://www.lacrossetechnology.com/bc1000/index.php

        the last one you get a heap of batteries with it but price is also US$ so need to search around

        thanks to everyone for the valuable in input here

        • Russ on 09/07/2014 - 20:49

          Both have their strengths and weaknesses.

          MH-C9000
          - can charge at 2 amps on all four bays simultaneously, if you need a fast charge (this can shorten the life of your batteries, so not usually recommended)
          - default charge rate is 1000mA, perfect for AA batteries, but too high for AAA batteries (use 300mA).
          - charge current can be set between 100mA and 2A, in 100mA increments, and you can set different currents for each bay if you want to.
          - larger display is easier to read, but only shows info about one battery at a time, and steps through the batteries.
          - the one from Protog comes with an Australian power plug, and plugpack has the "tick" of Australian certification

          BC1000
          - when charging four batteries, maximum charge current is 1000mA.
          - the 200mA default charge rate is too low for -dV charge termination detection, and will give a slow (14+ hours) charge for most AA batteries.
          - on the plus side, has over-temperature detection - important if you are charging two batteries at 1800mA
          - will need a US-AU mains adaptor. Using these could void your home insurance if it causes a fire, as the plugpack isn't AU certified.
          - Cheaper than C9000
          - Smaller than C9000
          - Comes with batteries and adaptors, but batteries do not appear to be the preferred low-self-discharge types, and adaptors are cheap on ebay.
          - Comes with some accessories like a bag.

          I have an MH-C9000, bought from Protog, and I'm happy with it. I sometimes buy Eneloop batteries, but prefer Hobbyking's "Turnigy" LSD batteries because they are almost as good and a bit cheaper.

  • ozzie freddo on 06/07/2014 - 22:52

    I am a bit dubious as the last "intelligent" charger I got from them (Active Energy Model EA-403D) claimed switching to trickle charging after about 10 hours, as well as a highly sensitive detector stopping charging once the batteries are fully charged, as well as when the maximum voltage has been detected BUT days later it was still putting the full 200mA charging current into the (previously healthy) cells. I've had to resort to operating it via a timer. Maybe I have a faulty one…perhaps I should make a warranty claim.

  • cheongk on 07/07/2014 - 22:00

    Bought one just now.

    Seems to be able to charge eneloops, Dick Smith LSD batteries ordered a few weeks ago and just received today, Medion LSD and Hobby King AAA LSD. Here is a picture.

    What I like:
    - Separate channels for each cell.
    - Able to charge 6 cells (AA/AAA) at a time if you are in a hurry.
    - Able to charge different types of batteries (incl. C/D/9V).
    - Shows % of charge (which is helpful).
    - Seems to be quite a nice build quality.
    - USB port on front to charge smartphone (if you need to use it).
    - No transformer, plug goes straight into mains socket.
    - 1 year local warranty (as opposed to buying something from ebay).

    Cons:
    I put in a couple of really old batteries (NiCd and NiMh), and it complained and gave an error. These charged okay in my Maha.

    Conclusion:
    I think that it's okay as a backup charger or if you have cells of different sizes. No regrets in buying it (at this time :)). Hope that this is helpful.

        I thought that I would use it when I travel overseas as it's 100-240v plus at $17.99, no big deal if I were to loose it. Also I don't have a charger for C/D and 9v cells.

          If you already have proper rechargeable C and D cells, you can ignore the rest of this comment.

          If not, then beware the Aldi C and D rechargeables, they have the same capacity as their AA batteries. They appear to be just an AA battery made thicker with cardboard. Buy AA batteries and get some adaptors from ebay instead.
