Contribute Data : Discharge information most welcome ...

If you own a charger that can discharge cells and give the mAh discharged , then please feel free to add data [ new cells please ] 

If you wish to cycle the cells , then please let us know which cycle you are sharing the results for ...  IE /   3rd Cycle 2200mAh 

Discharge rates : And charge rates 

AAA Cells = Please charge / discharge / cycle @ 0.5A [ 500mAh ] 

AA Cells = Please charge / discharge / cycle @ 1A [ 1000mAh ] 

RCR123A = Please discharge / cycle @ 0.5A [ 500mAh ]  Most chargers - WF-188 / 139 etc will charge at 500mAh or less , so not really an issue 

14500 = Please discharge / cycle @ 0.5A [ 500mAh ] 

18650 = Please discharge / cycle @ 1A [ 1000mAh ] or just let us know the dischargerate ! 

10440 = Please discharge / cycle @ 300mAh 

17670 = Please discharge / cycle @ 1A 

If you wrote a review - or tid bit on the cells , please let us know so we can link to your thoughts ..

Information = Charger used , cell dimensions [ use care not to short ] claimed capacity ... an example is bellow .

Just testing ...   But looks like this will work ... 

Ok , so hopefully something like this , so battery is tested / reviewed ...

Results for capacity go here + other details , + in the description [ battery ] , if there is a review [ I will review any batteries I test ] , I will link to the review , as I have done on the test form .   So I will keep this to play with [ learn ] 

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Ive set up a new Email for paypal , and will test , so hopefully will be able to accept donations shortly towards batteries . 

I'll just get my brother to try and donate $1 to see if it works ok ...

Just a thought.

Google Docs is quite useful for making this data accessible - I just copy and paste stuff for the output measurements from a master spreadsheet.

 

The numbers from my light tests are always to be found here.

Ok , supposedly new generation , 2100mAh capacity , and 85% capacity @ 12months , so I guess that makes them LSD ...  [ Low Self Discharge ]  

For those in Australia , Dick Smith has them for $10 @ 4 pack .. [ Feb 03-11 ] For how long ?   .

Anyhow , Im just waiting for the MH-C9000 to become free ...

I will discharge first to see capacity out of the packet , then charge / discharge and charge again ...  

 

Some results in :  Discharge from packet ..

Cell 1 / 1729mAh @ 1A discharge  [ Approximately 82.5% ]  

Cell 2 / 1757mAh @ 1A discharge [ Approximately 84% ] 

Cell 3 / 1745mAh @ 1A discharge [ Approximately 83% ] 

Cell 4 / 1713mAh @ 1A discharge [ Approximately 82% ] 

 

Ok , charged them at 1Amp , then discharged them at 1Amp 

Cell 1 / 1994mAh = 95% of claimed capacity

Cell 2 / 1965mAh = 94% of claimed capacity

Cell 3 / 1972mAh = 94.5% of claimed capacity

Cell 4 / 1987mAh = 95%  of claimed capacity 

Well , thats not too bad ...  especially as Im discharging at 1A .

???????/  Results are discharge out of the packet , I dont know if they push 100% charge into the batteries , or simply a charge that will hold as long as possible in storage , until there sold ?

Im currently charging them , so will see what the discharge is after a full charge ...  

But I think most people dont give out of the packet results ...   But I will  ...  Since some people might buy them and keep them in the package till needed , or simply use them straight out of the package ...

They aren't fully charged out of the packet. Should be 80%-90% full, IIRC.

I forgot about that! I expect them to hit 2000 + after a few cycles

Those numbers are not too bad at all.  Especially since you are discharging and charging at 1A.  I wonder how their charge would hold up over time.  I've been doing my own self-discharge test on some batteries since April of last year and so far my original eneloops (after 41 weeks) and my duraloops (after 40 weeks) are still at 100%.  My powerex 2700's are still at 80% (after 43 weeks) and only started dropping down to 80% after weeks 36 and 37.

No kidding? That's really good. Do you run them completely down to 0? What current level do you charge at? I have 4 Eneloops, and they don't seem to have deteriorated much after quite a few months of use.

I'm using my ZTS MBT-1 tester to check my batteries every week.  I always test a brand new set of 4 batteries and always after a break-in with my c9000.  I know it's a very simple and not a very battery scientific way of doing a self-discharge test but it gives me something that I love to do.:love:

Ok , just arrived from Tasmania ...  Vapex AAA  LSD [ 80% capacity after 6 months - 70% capacity after 12 months ] 

950mAh Typical , 900mAh Minimum capacity . 

Normal charge = 15hrs @ 95mA , rapid charge 1700mA . 

Cells were purchased off Ebay ...  

Currently discharging straight from the packet ...  @ 0.5A 

Results are in :

1/ 432mAh @ 0.5A [ straight from the packet ] or 45%

2/ 342mAh = 36%

3/ 187mAh = 20%

4/ 330mAh = 35% retained charge ... 

Well , thats all over the place , I might guess , A- old stock maybe , B-not so flash batts , C-counterfeit ?  possibly .  

Anyhow , early days .. Time to charge and discharge then charge again ... 

Ok discharged @ 0.5A from being fully charged @ 0.5A

1/ 887mAh = 93.4%

2/ 899mAh = 94.7%

3/ 905mAh = 95.3%

4/ 898mAh = 94.6% 

% is of the claimed 950mAh capacity ...

Ill see if i can get my HobbyKing LSD 2200mA cells tested. Ive had them for between 2-5 months and used them on my D10 torches, which pull about 2A on max, which I use about half the time. The cells range from having 2-10 discharge cycles on them.

I charge my cells on a Varta AA USB/12v charger which charges at 0.6-1A per cell in 1 or 2 pairs respectively. I will try to do a discharge and charge cycle at 1A on my icharger106+ and post my results.

So far unscientifically, the runtimes on these cells have been very impressive, especially when the cost of the cells are considered. I think it works out to be about $2 a cell shipped

 

PS... What voltages do we discharge to, im discharging my NiMh now, but where do i stop. 

 

Ok 1 cell Discharged - 

Cell was purchased December 2010, arrived Jan 2011. So far this is cycle number 2 on the cell ( I think)

Charged on Varta charger about 2 days prior.

Discharged at 1.0A on icharger, cutoff set to 0.7v

Capacity measured 2150mA , Time 2:07

Cell was barely warm (not a scientific measurement)

Floating voltage immediately after discharge termination back to 1.00v within 10 seconds, 1.20v within a couple minutes.

Subjective monitoring of the voltage showed a relatively flat discharge curve, holding 1.2 initially, dropping to 1.1v by 1000ma, holding 1.1v to about 2000ma, dropping to 1.0 by 2100ma, and rapidly falling below 0.9v by 2130ma and cease charge at 2150ma. This appears to be a very well maintained discharge curve, which in a practical application of my D10 torches means I barely get any warning of a flat battery.

 

Heres a link for the battery

If enough of us want to buy it, make a swarm, gets cheaper too.

Termination voltage ?   I think the Mh C9000  terminates @ 0.8v not sure , I havent seen it go lower than 0.9v ...

Convention says 0.9V - AFAIR that is what Maha set it at. My Angeleyes devices stop at 1.0V - I doubt the difference is significant.

 

The numbers from my light tests are always to be found here.

Well As you have both said, and according to the discharge plot of the NiMh, its not all that relevant as at 1.0v practically most of the capacity burned up anyway. I found the significant voltage drop to occur after 1.1 to 1.0v, so a cutoff at 0.9v should cover the capacity of the cell.

They look interesting , but shipping kills the deal ... Great for pick up ... 

Please include dimensions of the battery and I will include your results .  

Thank you

My brother got these , so Im borrowing them to test em . 

850mAh Capacity and 85% after 12 months ..  Just discharging them out of the pack ATM @ 0.5A 

Discharged @ 0.5A straight from the packet 

1/ 664mAh - 78% of claimed capacity

2/ 673mAh - 79%

3/ 677mAh - 79.5%

4/ 681mAh - 80%

 

Ok , 0.5A charge followed by a 0.5A discharge 

1/ 774mAh = 91%

2/ 793mAh = 93%

3/ 790mAh = 93%

4/ 804mAh = 94.5% of claimed capacity

Can you recharge them and test again please? I have the same ones in my mouse and I am really interested in their full capacity. I also got 5 pack of AAA Turnigy from hobbycity, which where half the price of GP recyko+, but I suspect they are pretty much the same in capacity and self discharge...

Standard AA or AAA procedure will be to test capacity straight from the packet with a ? discharge , then charge @ ? , rest , and discharge again @ ? to test charged capacity .

Since this is a flashlight forum , I dont want to discharge them at a lower rate as most lights on high will draw much higher current .

A pair of those cheap AAA Chinese [ VIA HK ] batteries showed up today .. 

Hmmmm , so how bad are they .....   Cry

1/ 358mAh discharged @ 0.5A after being charged ..

2/ 314mAh discharged @ 0.5A after being charged .. 

Thats less than half the capacity of most brand name cells ...  

I will pop them in a remote and see if they have any longevity at all , I cant see anyone wanting to use these in a flashlight ...

You mean they meant One 350mAh  and they put on 1350mAh ...

LOL!  and the 1 is spaced out further from the other numbers too!!!

 

 

Regarding the Turnigy AA NiMH I was testing, Im now away on a rural clincal placement and I dont have the tools to provide measurements for another 2 weeks. If I find the time, ill organise more battery tests on the few cells I took with me.

So far, Im very impressed with the cells, and the shipping isnt too bad for me.. but for cells alone, and maybe compared to other budget places, maybe not so cheap, however I do feel safe ordering from Hobbyking, which is where all my model plane stuff come from. Got the icharger from there too! There is a discount if you open the page for an item, and leave it open for at least 5 mins without closing it, for the first time for that IP address I think?
