The BLF Battery Data Base

Adding to my hobbyking "Turnigy" LSD AA 2200mA

Another discharge at 1A to 1.0V gave 2184mA, this cell is also 2nd or 3rd cycle I think.

*Sorry, Could you add this data to my previous entry, New Data should be as below.

And a bad low light photo for you, except I drew numbers all over the battery...


Im curious too. The price is amazing if they are in fact real Sanyo's. I did some research and couldnt find anyone who's bought and tested these yet.

I got mine from Ebay - [ are they the same ? lot ]

In case anyone was interested, just finished up recording a rundown test on a 11.1V li-ion protected pack made out of the Sanyo 2700 mAH cells (UR18650ZT).

The test was using a 10W halogen bulb as a load, so almost a pure resistive load. Average current draw was around .8 amps. Results were very near the ideal 2700 mAH capacity (at room temp). More importantly, the percentage increase in run time over the 2200 pack (roughly 23%) was right on the money. Cells came from SoShine. According to the manufacturer's specs, you do pay a hefty penalty with discharge currents above 1C (2.7 amps).

You can see the voltage vs. time plot over on my site:

D-10.1mm

No MH-C9000 Button Top

These cells aren't entirely new -- I bought them together with the C9000 a couple of weeks ago -- but they've only had a break-in and/or refresh/analyze cycle and a couple of very partial cycles in a flashlight for a couple of the cells. I ran two cycles of 500mA charge/500mA discharge and am reporting the second (which was 10-15mAh higher), so call it the fourth cycle overall for the cells.

I don't have calipers (so I eyeballed size...)
Edit: Measured one at 44.30mm x 10.17mm with digital calipers.

4x Ansmann maxE+ AA (LSD)

2500mAh (2400 min) 2nd cycle: 2172/2161/2188/2197 mAh @ 1.0A No MH-C9000 Button Top

The other package of NiMH cells I bought together with the C9000. These have been discharged (didn't write down the numbers, but around 1700-1800 mAh out of the package) and then given a forming charge. They then sat a couple of weeks until I started them cycling for this test. They're actually still in the charger on a third cycle, but the numbers are quite close between the first two cycles, with two cells showing higher capacity in the second and two cells lower (differences of 11, -25, -17, and 10 mAh).

[Edit: the numbers for the third cycle were virtually identical (differences +1, 0, -2, and +4 mAh), so I'll let the 2nd-cycle numbers above stand.]

The reported capacities during the break-in cycle were also around 2200 mAh, so it's not simply voltage sag at 1 amp causing the low numbers.

Edit2: Digital calipers say two of the cells are 50.32mm x 14.08mm and 50.30mm x 14.07mm, respectively.

Aloha and welcome to BLF ralf and pethelman!

Hmmm..

From all of the testing done on 18650 batteries, one could make the assement that any 18650 with a claimed capacity greater than 2400mAh is in reality only capable of around 2400/2500mAh.

So is there any real reason unless it's a good deal to buy a a set of 18650 greater than 2400mAh?

I mean the difference of +/- 100mAh is no big deal, but why buy a cell that claims lets say 2800mAh.

i dont have any cells above 2600mAh claimed to test, but from the test numbers there is no real reason to. The gains if any diminish greatly the higher claimed capacity.

Pretty good at price/preformance.

I got five of these from Hobby King. Here are the results for 4 of them. This is about the third cycle on these. I used a Maha Powerex C9000, charged at 600mA, discharged at 500mA. The key with the C9000 is to leave the battery in the charger for an hour after they say they are done charging because it applies a topping off charge.

Results were 842, 850, 861, and 854 mAh. Average is 852. Dimensions were 10.2-10.3 diameter and 44.2mm long.

Just bought AAA eneloops, and used a 350mAh discharge, (max on my Voltcraft ICP 1L ala Lacrosse BC700)
batteries are made in May 2011..pretty new though..

cell1: 765mAh = 102%

cell2: 730mAh = 97%

cell3: 733mAh = 97%

cell4: 744mAh = 99%

After a night on my Voltcraft it had been a few times discharged and recharged, and the following day the numbers are

cell1: 860mAh = 114%

cell2: 836mAh = 111%

cell3: 854mAh = 113%

cell4: 857mAh = 114%

Top Craft "Ready to use" AAA batteries, rated at 850mAh (the Red ones, bought in Holland 4 months ago.)

they had been in my SolarForce L2i for about 4 months, and used a couple times.

I wanted to see how much juice was still in them

cell1: 758mAh

cell2: 735mAh

cell3: 740mAh

Was still surprised they were in that range after 4 months and a little use...

did a Refresh on all

cell1: 896mAh

cell2: 908mAh

cell3: 896mAh

People ask about these from time to time , and my brother got suckered by these [ yeah - he should have asked ]

Anyhow , I ran one through my Imax B6 @ 500mA discharge rate

Drum role plz ............... 970mAh capacity when discharged to 3v [ Wow thats one heck of a 16340 !!! oh wait , itsa 18650 ? ]

There you have it , CRAP in a wrapper !

Dare I speculate ? Perhaps these cells came from a dumpster outside a chinese battery manufacturer , Id hate to think one of the manufacturers would sell reject cells to anyone to put in a wrapper and sell to the public ..

But thats what these are in my opinion , crap in a wrapper .

To claim 3000mAh capacity and deliver 970mAh , Dare I say it would be nice if some of the online Retailers / re-sellers simply would not stock rubbish like this , it would be nice if they attempted to maintain some sort of standard ! [ It would be nice ]

Dare I say , these batteries are for the punters , want a sure thing , buy something tested and proven .

Ultracell 11000ma D battery. Ordered on Ebay these are way under claimed capacity. Of 4 D cells 1.2v checked at 3900ma average, discharged at 2.0A to .9volts.
