The BLF Battery Data Base

i feel sick when i receive the such table. and some need to fill in the blanks, hahaha

Batteries came from www.szwholesale.com , thank you .

Ok I just completed discharging 2 of the 2200mAh 18700 , well , late last night actually ..

Battery 1 returned 2151mAh @ 500mAh discharge rate

Battery 2 returned 2161mAh @ 500mAh discharge rate

These results are excellent for a 2200mAh rated battery .. Discharge was to 3v termination and started with the battery at 4.2v

PS/ There will be a complete review posted , so this is only the discharge portion .

Batteries came from www.szwholesale.com , thank you .

Ok , discharged the 2400mAh Xtar cells @ 500mAh from 4.2v down to 3v ..

Cell 1 did some 2468mAh

Cell 2 did some 2485mAh

Now this is quite a first for me , cells actually exceeding stated capacity .. [ Well done Xtar ] , Its late , and I will discharge the 2600's tomorrow .

Looks like Xtar batteries will be next on my list.

Thank you old4570 for all your hard work and all the $$ you spend to share with us all of these battery reviews.

The first Xtar 2600 built on a Sanyo 2600 has been discharged .. And much like the Sanyo I tested a little while ago Here , the capacity tested was very close ..

2433mAh for the Unprotected Sanyo , and some 2448mAh for the Xtar [ Sanyo 2600 based ] , Im currently waiting to put in the second cell , and I want to time it so it will finish a little after I get back from the Flashlight Meet tonight .

Ok , back from the meet , and the second one went 2438mAh .

Next will be some discharge [ for current ] tests ... , So hopefully will be able to post a review shortly .

Intresting, so far at 500ma the 2400mah cell actually has slightly more capacity than the 2600mah cell.

I guess the 2600mah will kick ass at higher currents though.

That reminds me, did anyone buy any of the "Sanyo 3.7V 2600mAh 18650 Rechargeable Battery" from KD?

I just wonder if they are genuine at that bargain price.

Duracell Pre-Charged LSD (Rebranded Eneloop, "Duraloop") AAA NiMH

800 mAh, Non-protected, LaCrosse BC-900 Charger in capacity test mode

Charge 500 mAh, Discharge 250 mAh (I can't do 500/500 on this charger)

44.5 m x 10.1 mm

Third cycle battery capacity results for 4 cells:

822, 854, 830, 871 (Avg = 844) These are decent numbers for a proven/reliable LSD battery (above spec).

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:

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.

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.

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.

Here is a post about these batteries: https://budgetlightforum.com/t/-/2598
