Hi I've just got the battery on ebay. It was sealed brand new. Looks fine. When i checked it against my previous battery box out from combo pack. The only difference i can see that you don't have a trademark next to "Mavic is a trademark of DJi" line. Also the switch button "click" feels different? i can also see the factory is different of both boxes. Another thing is that on the box  it says 2018/6. When i put SN number to encoder it gives you april 2017 but in the app it says 11/2017. I must admit that when ive put it to mavic it doesnt show any issues. I've tested this for couple of minutes-no problem. After first switch on it did the update as well? SN: 093XF5Q04502WB Could someone advice if its definitely Genuine Dji battery?

When flying, your drone depends on the battery. You are most unwise to mess about with such a critical component.

Well, I cannot see why this should not be genuine Mavic Pro battery. Then only thing i don't understand why decoder says manufactured date April 2017 but in the DJI app on the  phone it says 11 2017?

Hi, Kaiser64. Can you please provide a photo of the battery that you had received? For me to check the physical body of the said battery and for me to help you further. Thank you.

I am curious about if this is a genuine DJI battery or a really good knockoff.  I have seen a few horror stories and potential failures from the after market batteries.  The experts do say in the end to always go with genuine DJI products.  Kaiser64 , very observant in finding those little differences!!

Am i not right saying that DJI app and mavic itselft would indicate problem if battery is not genuine?
Like i said it went through updating ok after taking off the box. Just dont know why it shows different manufacture date in the app and using the encoder for this serial number
