I wouldn't know if they were genuine or not from an ebay link tbh.. the seller could have used a stock photo and then sent you something entirely different.
If you can take a photo of your battery and put it up on here, then someone might be able to give you an informed opinion (not me though.. I'm no expert when it comes to fake vs knock off batteries, I tend to buy my batts from reputable vaping vendors and trust that they wouldn't stock fakes).
I'm not trying to scaremonger you here btw, the battery may well be fine to use but it pays to be a bit overcautious when it comes to lithium batteries because they store quite a lot of energy and can go with it bit of a bang if things go wrong.
