Seems like I got a six-pack of counterfeit/fake Samsung ICR18650-30B cells :-/

Thanks for pointing out the date code stuff, RobertB.

Got some numbers for you, moderator007: 9L17D1823R9, 9L17D1822R9, 9L17D1821R8… These are underwrap longitudinal orientation codes, and even the last one’s characters had oddly shaped, stretched out characters. They don’t look like the eBay cells in this regard.

Cheers :partying_face:

This cell being discussed is a 30Q so I dont know if it applies to a 30B as far as date code.

Samsung date codes

Hi sixty545. I’m fighting a virus right now and my thinking is very fuzzy right now, I can’t seem to make sense of what you have reported. I’ll reread your post tomorrow when I hopefully feel better. Thanks for taking interest in this matter. It will be great to be able to determine date of manufacture for these types of cells. I see the code that you mentioned. It’s a bit faint, but can seem through the wrapper. One of my 30q cells has the following label near the positive end: JOF8 67FC1 A…

I searched but I don’t think any one has cracked the code on the can completely but dates should be the same between wrap and can I would think.
