Superfire 18650 with protection circuit . 

Claimed capacity 2600mAh ...

Wow , ok I dont know what to say , I ran it through twice since the results were So Bad ! 

759mAh @ 1A discharge 

855mAh @ 0.5A discharge 

Ok , was I testing a 18650 ? 

 

2nd Cell = 946mAh @ 0.5A discharge

The resulting sound may , or may not be worth listening too ….

Testing the other cell now ..

these go 1.49oz  VS 1.67oz for a ultrafire , so weight wise ?  not really suspicious ...

As soon as the second one has discharged , so I can confirm ...

There deff on the cheap side !

But I just spent $130 on a text book , and one would expect more such surprises as the days go bye ..

Geez these folks should have had a book list available last year , so I could source the books from the cheapest vendor rather than get ripped .

Bying books after schools starts ... Yeah doing a IT course this year , as my back is worn out from being a human forklift .

Geez these folk did not have there act together at all , this last minute stuff is realy pissing me off .

Just wondering how much more expensive today is going to get ?

Sent to me by Forum member Noodles , one white Trustfire 16340 ..

Picture hosted by : http://wwww.imageshack.us 

I charged the cell to 4.2v , and then discharged it for all of 53mAh , thats right , 53mAh capacity ! @ 0.5A discharge 

I think I can understand why Noodles was not impressed .  Im charging the cell ATM to see how much goes in , since it took so long to discharge . 

Wow , @ 0.5A charge rate which never held , it started @ 0.4A and very quickly went to 0.1A but before I could even finish this post its done , charged all of 52mAh ..

Im going to toss this one , it could be dangerous , this is a very bad cell ..

Thank you Noodles !  for bringing this to our attention ! 

 

Just to check , I ran a AW through , and got 578mAh [ 2 years old and maybe some ] 

And that Trustfire seems to be getting worse every time I charge / discharge it ...

Thanks old,  that package got to you pretty quickly!

these cells only had a few reviews on DX ( sku11670), but I went ahead and ordered some anyway.  They all perform about the same as the test cell, so they will get tossed. 

I need to get a hobby charger to start profiling all the cells I have.

I got my maha c9000 today, tested some brand new maxuss aaa, claimed mah 1250.  Didnt know what I was doing and only set one battery on refresh analyse. Other 3 charged.

Im charging/ discharging now at 500 mah. 

results

1. 632 MAH

2. 632 MAH

3. 582 MAH

4. 618 MAH

Disappointing as claimed capacity 1250. Another dx scam.

Could be they're not rechargeables? "Warning: Battery may explode or leak if recharged"

 (but the battery cover says "do not ... charge improperly", so probably just tmart's fault)

 

And thanks for all the hard work! A really good project.

great news got my accucell 6 in the mail, and tested it on a 12V lead acid battery i thought was dead.

it was charging on its own charger in less than an hour, and was dead in 20 mins (35watt HID was the draw)

after using the accucell 6 to drain it completely (at 1 amp) and recharge it completely, i was able to milk about 2.5 Ah out of the OLD 4.5AH battery it was

good enough for HID use now!

saved me 20 bux for the time being!

 

now, i shall due some serious testing with batteries, after looking at the list, i see we dont have the Old Sanyo Ni-mh, energizer ni-mh, nor powergenix Ni-zn.

so those will be my first submissions (will do on wednesday, its my day off lol)

also have the trustfire 18650 flames, 14500  and rcr123's.

 

can someone suggest a battery holder that may plug into the wiring provided for my charger?

It's a bit hard finding 18650 holders. I got these,

http://www.virtualvillage.co.uk/5-x-rechargeable-18650-3-7v-lithium-batt...

but they are a bit on the long side - I need to stick a 2mm thick magnet on the end of each 18650 to get reliable contact.

If you want to balance charge you need to make up a balancing harness as well - the simplest way is to buy a balancing lead extension and cut off the female end. I 5think i got my cables from eBay but HobbyKing probably have them.

 

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

Same company I think. Though I think mine were posted in the UK - they certainly arrived much faster than most HK stuff

Hi All,

First post here.

More capacity data on these Vapex AAA 950 mAh LSD. (Already tested by old4570). Sourced from ebay.

Out of packet (0.5A disch):

1) 128 mAh

2) 372 mAh

3) 0 mAh

4) 762 mAh

 

Charge/Discharge at .5A

1) 869 mAh (91.47%)

2) 910 mAh (95.79%)

3) 861 mAh (90.63%)

4) 868 mAh (91.37%)

Measurements from Maha c9000 (6mths old)

 

So broadly in line with old4570 results.

I wouldn't want to rely on these straight out of the packet!

I am interested to see if they have poor LSD or if the original prepacking charge is the cause of the wild differences in capacity out of the packet.

 

I enjoy the site.

Cheers,

Tim

I also tested the AA Maxuss 3000 mah batteries. About 1750 mah. But I had recharged them 2 times so they are not new. Don't buy them http://www.dealextreme.com/p/maxuss-1-2v-3000mah-ni-mh-aa-rechargeable-b...

I got an 8 pack of eneloops from an OZ seller. Came in a clear packet- no label or anything. They look legit as far as I can tell. Currently discharging straight out of the packet.

Maxuss AA  3000 mah from DX

http://www.dealextreme.com/p/maxuss-1-2v-3000mah-ni-mh-aa-rechargeable-b...

Tested 3 so far.  2 cycles

1. 1750

2. 1731

3. 1800

Maha c 9000

Button top

Length 50 mm

diameter approx 14mm. sorry dont have a digital caliper

Very poor performance against claimed capacity. I wonder if they are re badged 2400 or 2000 or are they  equally poor performers.

I have some ready to use Varta aa  2100 and 2500. I will not post results as they are not new and have been "cooked" a few times on the 15 minute charger. I noted that the 2100 has been charging for almost 3 hours and the capacity was 2400 mah and climbing. The battery felt overly hot so I stopped it charging. I'll buy a new pack and test soon.

Just got a pack of Trustfire grey 16340 protected. I'll try to find a way to asses their capacity to contribute to the list.

Soshine 1100mAh Ni-MH Rechargeable AAA Batteries with Case (4-Battery Pack) from http://www.dealextreme.com/p/26987 ($6 shipped), non LSD

La Crosse BC-900 charger. Brand new cells.

Charger Test mode results: 1022 1007 1035 1050 ma (charge 500 ma, discharge/measure capacity at 200 ma, recharge at 500 ma, cool down)

2nd cycle 500 ma Discharge mode results: 1050 1066 1078 1096

I think these are pretty good numbers for inexpensive AAA cells, and they are nicely consistent across the 4 cells.  They also get good reviews on DX.  They arrived almost 100% discharged.
