Please help identifying these salvaged cells

I opened two recycled Dell laptop battery packs and got 18 pcs of these:

It seems to be a LG cell and based on the pack information it should be 2600mAh. Can anyone help with further details? (can’t remember seeing this color before)

First nine were 4.25V and second nine 4.18V each.

1st cell gave only ~1100mAh with 1A discharge, but I have to check the capacity again after recharging..

Looks like you got them out pretty good. I did that and had some messed up ones. Maybe better luck next time, lol.

Is the insulator on the top white? If so I think it may be a ICR18650C1, which is actually a 2800 mah cell. 

They are the special ones that charge up to 4.35 volts, however charging them to 4.2 will lead to less capacity. They are rated for a 2c discharge so 5.4 amps. If you need any other info tell me. Big Smile

Yes, the insulator is white. That would explain the 4.25V reading as well. Sounds good!

Thanks for the help!

Yeah, I have taken apart dozens of battery packs and I just have a document with datasheets for each one in it.
