As a general thing, most electronic consumables sold on ebay are not just potentially fraudulent in some way, they are almost certainly fraudulent.
Ebay fully condones this and lets listings run despite numerous
bad reviews. I think the theory is that only a relatively small
percentage of customers will complain and demand a refund, so ebay
overall makes a good profit from it.
I have at times bought (and often returned) Lithium cells, Phone
batteries, Cordless tool batteries, CF drives, and solar panels
Batteries, individually, for laptops, phones, and tools are notoriously listed at far higher capacity than actual. That, and the brand is often faked as well.
Another big fraud is compact flash, where brand is very likely faked, and/or the parts are repairs or fakes in some way, such as replacing the micro controller to report different manufacturer and/or capacity.
To be fair, supermarket CF have problems, such as overrated speed
performance or CF labeled one brand on the shell, but reporting
some other brand electronically. Inevitably these drives do not
last in applications for computer drives. My standard for CF now
is to buy genuine SanDisk or Samsung drives from an authorised
distributor
