Do you have a datasheet for them? The only information I could find online says they're rated for 2500mAh but typical performance is 2600mAh - meaning they usually test better than spec.

I have some of these but they have the blue rings. The blue matches the UR18650F in the database but they are labeled UR18650FM. Just thought I'd let you folks know. Great job with the db by the way.

I also have a bunch of the UR18650FM that also have the teal/blue-ish top and they are testing around 2500mah+.

Can you confirm you can see "FM" on the wrapper? Not just "UR18650F"? If you can confirm, I will create this as a separate variant of the FM cell.

Looks like SANYO cells have random color rings, or at least a couple of different colors per model nr. Maybe adding an "i.e. "white/purple" text in the ring color would be better, as opposed to over-populating the database with duplicate -as seems- entries?

I can confirm having light blue isolator with "Sanyo L" and "UR18650FM" on them wrapper. Dont know if its the production code, but there is R1122 right beside and P15C below.
