New Imedion 2400mah LSD AA Batteries

[Foxx510]

I have bought stuff from that guy before- look forward to giving them a go...

Jeff runs a very reputable business from my experience and what I've heard from others. I'll be keen to see what the testing reveals.

I hate to be the one who tells you this, but the new eneloops ive got (1500x rechargeable series) also read these kind of numbers on their first couple of charges (2100-2140 range) so on that part there's not yet very much improvement...... Please do post back here if these numbers improve after a couple of cycles!

For some reason I am really skeptical about this for the simple fact that eneloops can't break the 2000mAh limit. Definitely be interesting to see how these cells will perform in the long run.

Can anyone reconcile these differing statements?

I think the second one was referring to the commonly known results of the first run of eneloops. Also I think he meant cant break the 2000mah barrier in a rough sense, many peoples eneloops have been doing 2050-2100mah already. It's just that 2400mah in a lsd cell is a big jump and has been advertised before by a few companies without any substance to the claims..

Lets just wait and see the results.

If this is true, This might give the eneloops competition.

Initial test results on the 2400 Imedions seem kind of mixed. The set I ran the break-in cycle on seem to be stuck at around 2200mAh. Another set that I started right off with "refresh/analyze" cycles is averaging around 2350mAh after several cycles.

Here's the first 4 cycles from the good set (which I did not run the break-in cycle on):

cycles-> #1 #2 #3 #4
bat #1 2228 2329 2332 2337
bat #2 2269 2369 2370 2374
bat #3 2244 2341 2345 2350
bat #4 2286 2381 2383 2388


Capacity seems to be pretty stable from cycle #2 onward, but still appears to be increasing slightly with each cycle. Still trying to figure out if I somehow overcharged & damaged the other set with the break-in cycle. I've got a 3rd set testing now as well just to make sure the above numbers aren't a fluke.

capacity looks promising, it will take months to determine if there are self discharge differences between other LSD cells.

Anybody get any of these yet?

Excellent numbers for a non-breakin. I'd like to see the numbers produced after a break-in when you get a chance.

These looks sweet! gtwace, thanks for the head's up on these puppies!

I've got a couple MH-C9000's running their "break-in" cycle on some of the new Imedions right now. FWIW, the old-style 2100mAh Imedions we tested seemed to average closer to 2200mAh, so I've got high hopes for these new ones.

Photon, I have to agree with you there. For those wondering about the Imedions, I purchased 8 x AA 2100mAh Imedion's early last year when I picked up my Maha charger and they are fantastic. I rotate my batteries and run break-in cycles every now and again and they are still showing as 2100+mAh to just over 2200mAh capacity after 1+ yr. :thumbsup: Also, since I rotate my batteries 2 x 4 AA at a time, 2 x 4 AA's tend to sit on the shelf for about 1 month at a time - not a definitive test for LSD but so far, so good.

Fyi, I also have 8 x AA Duracell white tops (rebranded eneloops) which I purchased in the spring... haven't put that many cycles through those just yet but they, too are showing 2100mAh capacity. It will be interesting to see when the capacity drops on both of the batteries.

I have to say that I'm impressed with the Imedions so far. I may have to pick up some of the 2400mAh Imedions if I can get my hands on them for fairly cheap. I'd also like to hear more feedback on the 2400mAh as well.

I also have it on good authority that PowerEx will be working their new Imedion magic into the rest of their battery sizes. Not just AAA, but apparently C, D & 9V Imedions are in the works too. Anyway, we'll update the info on our Imedion 2400mAh page as soon as we've got some numbers from the capacity testing.

I would definitely be interested in the C size Imedions...

Just a brief update on my testing -- It appears the huge difference in tested capacities between the two sets of batteries may have been due to one of the chargers not measuring accurately rather than anything to do with the batteries themselves. To speed up the testing I've been using two MH-C9000 chargers, but it appears the second charger has been consistently stopping about 100mah short of a full charge. Out of curiosity I tried swapping the batteries between chargers and immediately the first set of batteries that seemed to only be testing to 2200mAh mysteriously gained a bunch of capacity and the other set that had been testing very well on the first charger suddenly lost a solid 100mah of capacity when tested by charger #2.

Ditto I am having exactly the same experience with 2 C9000 chargers. One of my chargers is a very early (Like first shipped) and the other is new as of three days ago. The newer one is reading about 100mah lower 2180-2260 the older one is reading 2240-2330. As I have 16 cells I am charging on 2 Lacrosse BC-900s. I am only 3 cycles in so far and I have been going hot off the charger right to discharge. I currently have 8 cells on discharge which have been off charge for 24 hours and tomorrow I will run the second set of 8 48 hours off charge. So far I am not overly impressed. More in a day or two.

After an initial charge of 200ma I am now charging/discharging at 500 ma.

Downunder update: Protog (used to be Servaas) has these on the website now for 17-21 AUD per 4pack. And cheap postage. I am interested but look forward to some current sourcing data, as well as longterm LSD testing. Anyone seen this data yet? If I weren't so lazy I'd start with 4 and test them. I wish I wasn't getting so old....

I see Thomas Distributing is carrying these batteries for the best price I've seen yet.

Hi All,

FYI, my wife just got a killer deal apparently. Snoop.com box of 6 x 2 Duracell Active Charge for like $18 (sale over now). Was ready to tell her to ship them back as I hadn't heard of them, and assumed they were standard NiMH and I've found my Eneloops to be the shiznit.

Not 2400ma like the Imedion, but you may want to keep an eye out for other deals like this, or on fatwallet or slickdeals. I would assume this is competition/Capitalism in action.

Hello everyone! :wave:

8 of these little gems just showed up in the mailbox from Thomas Distributing! :huh: Needed sometihng to power the TK45 thats also on the way

Out of the package OCV is...

1.315
1.311
1.316
1.313
1.315
1.311
1.309
1.310
​

The first 4 are undergoing a 500mAh discharge in the C-9000.
Initial capacity and break-in results to follow.

The 2400mAh Imedions were just released last month so not likely to see any long-term LSD tests for some time yet.

 

[snakebite]

anyone find a datecode?it probably takes several months from the day of mfr.to "getting in the pipeline".
where were these made?
some good pics might help pin down the oem.

[adam83]

Capacity of my 8 new Imedions after a C-9000 refresh&analyze
2232mAh
2237mAh
2228mAh
2194mAh
2214mAh
2227mAh
2216mAh
2187mAh
I have not done a break-in cycle yet, hope to accomplish that in a few days.

I can not find a date code anywhere on these cells. They are made in Taiwan. Here is a shot and some comparisons to a Duraloop and a ROV Platinum

More testing to come!
