Is this a genuine oem battery?

Hi,
My 15'' macbook pro's battery is not working well, so I would like to get a replacement battery.
After searching through a couple of sellers on ebay and Taobao(Yes, I'm in china), I found that most of them are fake ones.
This is a battery from one of the seller who claims that his battery are genuine.

Below, This is a picture of my battery from my macbook pro, A1668, of course a genuine one.

I can see the sellers' battery printing is different from the one inside my mac, does anyone know if the seller is selling genuine or fake ones?

There are no genuine original Apple spare batteries because Apple isn't selling spare parts to anyone.
The only place to get a genuine original Apple battery is getting your battery replaced at an Apple store. Everything else is going to be 3rd party regardless of claims and promises.

As above, same goes for replacement iPhone screens etc. The only place to get the real deal is from Apple themselves or an authorised repair centre.
