NCR18650b - MH12210B - Spec?

I have 4 NCR18560b’s here, Marked up MH12210b.

They are usual lime green, unprotected, and carry the code
E (bv)
5604

Internet says they are 3400mAH.

Sadly they are too short to fit in my EC4S.

Anyone know if they are likely to be genuine, and if so, how much current can i safely pull from them ?

Thanks in advance, and happy new year !!!

You should find all your info here

As for being genuine...most likely.

The latter is Panasonic’s UL file number

A simple google search reveals the original datasheet.
