How do you know what you're getting? I bought these Sanyo NCR 18650GA from Orbtronic. Does this "B" mean they are "B" Grade cells? If so, who can I trust not to sell me junk cells without disclosing it first? If not, what does the "B" mean?

Probably came off line 'b' that day. If they are on spec for voltage and capacity then you are good. They meet a minimum spec to pass q/c.

For all we know, the "B" is used internally to indicate a cell that was sold to a third party vendor and not directly by Sanyo with their own wrapping.

About the wrapping... due to the warning it looks like they were destined for retail. Cells in pre-assembled packs (laptops/etc) don't usually have consumer friendly warnings.

Re: "A" "B" and "C" grade cells?

I just received my 6 18650GA cells and i see the letter B on them. Out of package voltage was 3.5v on all 6 cells.

On the invoice, it did states: Due to strict regulations, the cells are shipped almost fully discharged and must charge before use.
