LGDxME11865 datasheet reference: https://baterie18650.pl/wp-content/uploa..._LGC-1.pdf

10A maximum discharge current, 2A maximum charge current, 2AH nominal capacity, 4.2V charging voltage. I believe the current information on this page (which seems to come from Voltaplex listing) is wrong. Correlated the same data with another alibaba listing for this cell.

I have been looking at the best options for solar panels for a small back yard and this thread definitely helped me decide like in this article https://websolarguide.com/am-solar-power...ng-lights/.

ICR18650NQ 2.6AH cell. Couldn't find any info from quick Google and Alibaba search. Came from a Cameron Sino CS-TOP100XL battery pack (replacement for BT-62Q, BT-65Q, or BT-66Q battery):

SG18650-22A - 2200mAH nominal. Didn't find anything with Google/Alibaba search, pretty old cell. Date code might be 11/2003.

You got the date code backwards, it's March of 2011. It's funny, I just took apart 3 packs of these. One pack was "recycled" and had dremel marks on the caps. One pack was all 0V, and 1 pack had cells between 1V and 2V. I believe these are re-wraps of used cells, but I don't have proof.

Yeah sounds like yours were reused. The caps look clean on my cells but the capacity was all over the place on the ones I recovered, highest was 1659mAH, lowest was 88mAH.. guess that cell is just considered dead. They do have the same look to them all though, so it's not like a mix of brands. I can do a voltage curve measurement to see if they line up chemically.

I have a bunch of non-translucent green SGs that perform well and have the same positive cap and sticker under the wrap as these translucent blues, so I'm thinking the translucent blues are rejected greens and not re-wraps of major brand cells.

Sanyo UR18650A with Purple top



I have edited the picture of the Sanyo UR18650A with a white insulator. I have the UR18650A with the Purple insulator.

I guess I have a new one here.
This one is dead. It was taken off from a Parkside power tool pack that for some odd reason it stopped charging.
I called the Manufacturer and they say they only guaranty the power packs for 6 months Angry
This pack was barely used and because it was just over 2 years old, it wasn't covered by any warranty.
So I opened up the pack and measured the voltage of every individual cell and found this one was dead and all the others were between 2.7v and 3.0v ish. 
I charged them back up individually while they were in the pack using my Liitokala charger and crocodile clips to 3.85v without any issues. 
I will keep the remaining 4 cells in case I need them for my other power tool batteries.

I also found some info online regarding a similar cell:
