Battery test/review summary

The Spark battery is based on a Sanyo 2600 mAh cell. I do have more than 16 batteries left to test and some of them might also be using Sanyo cells.

It´s a good Price 5,90 $

sorry - i have no more Information

They are not in my test queue and I am not going the buy new batteries to test, before the queue is significant smaller.

I have bought these batteries and just have got delivered. Exact name is Sanyo UR18650FM R01122.

Are better at least around classes than my present Trustfire TR2400 grey :-)

Added 7 more batteries to the charts. I might be necessary to press F5 to update the charts.

I do still have batteries for about two months testing left.

At the start of January:

Left is "to do", middle is "testing" and right are "test done"

And today:

The to do pile is larger now!

Awesome.. already some Himax in there? :P

HKJ, are you only testing Li-Ion 18650's? I'd LOVE to see proper review of A123 LiFePO4 18650's, considering they are claimed to be capable of 30A load.

No, manufactures and dealers has been supplying the batteries, I have not bought any new batteries the last two months (At least not for test, but I bought a pile for general use).

No, I did test the AW IMR18650 with up to 20A load. My current test rig can test with up to 30A and if I combine my testing stations, rewire and modify my script I can do 60A, but that will not happen while I have a lot of batteries to test.

At the current time I try to reduce my to do pile, i.e. the only new batteries that are added are the ones send from manufactures and dealers, I do not buy any.

Somebody had a good idea on how to compare batteries and I implemented it in my full comparison.

Now it is possible to compare any tested battery at any current to any other tested battery in my 18650 test. The result looks like this:

The comparator can be found here.

And again, thanks for all your hard work.

This tool just made your tests even better.

The UltraFire 4000mAh and all the 18xx0 Keeppower batteries are now included, both in the above bar charts and in the full comparison on my website.

It might be necessary to press F5 to update the charts.

Added 3 Keeppower batteries: 2600, 2800 and 3000. It might be necessary to press F5 to reload the charts.

Note: for 2800 and 3000 only the 4.3 volt charging is present, to see the 4.2 volt curves use the comparator.

Since my last note about added batteries I have added:

LG 3000mAh
AW 26000mAh
3 Orbtronic batteries: 3100, 2900, 2250 (High current)
LG 2800
PALight 3000mAh (A cheap battery)
I have also published test of TrustFire 3000mAh, the test includes batteries from 3 different manufacturers, but I have not added the result to the charts (For comparison use the comparator)

You have your work cut out for you.

More batteries have been added:
RediLast 2600mAh (Black)
NCR18650A protected (Green)
TrustFire TF26650 5000mAh (Flame) from one more dealer (Not included in the charts).
Fenix 18650 ARB-L2 2600mAh (Black)


My stock of batteries to test is nearly exhaust (Slightly over 1 month testing remains) and I am open to suggestions about other batteries to test.

Edit:
All the batteries:
Front: Working on
Middle: In queue
Back: Done

The Panasonic NCR18650B 3400mAh 4.35V cells (I already suggested them to you on CPF, but I guess suggesting them once more here won’t hurt) :Р

They're available for sale on cnqualitygoods.

I did see that and are already looking at cnq, but I need to find some more stuff from cnq to offset the $30 custom fee I will have to pay. Maybe one of the 26650 batteries and a 18350 battery?

And that cell is 3 weeks test time, if I do run it at all 3 voltages (4.2, 4.3 and 4.35).

I will test the NCR18650B, but it will be some time before I receive them.

Looks like cnq was wrong, the cells are 4.2 volt, i.e. they will "only" take a week to test.
