I received my Asus N55SF battery replacement and the first thing that I noticed were the black marks that suspiciously covered the battery. I immediately thought I had gotten a non-genuine battery. However, it looked genuine and it aside from the marks it looks exactly the same as the battery that originally comes with my laptop. I inserted it into my N55SF laptop and it works with zero issues.
Curious, I actually emailed them about why the Asus brand name and why even the word « Korea » had been crossed out on my Asus N55SF laptop battery and they said that it is due to their shipping company not allowing it, and customs. They suggested using alcohol to remove the black markings and it worked for me. I had bought a laptop battery on eBay which only lasted for one year and I compared it with my original Asus one and the eBay one. The Storebattery.sg battery is definitely original.
Aside from the production date sticker, pay attention to the *exact* placement of the printing on your battery ; a fake one usually has the printing slightly off-centered, or it might just seem a little too sharp. Impossible to tell from pictures alone though.

I like that Storebattery.sg shows you a video of the laptop battery. Interestingly, the video directs you to another sister website www.laptop-parts-shop.com which confused me for a while. I ordered from Storebattery.sg because it is closer and cheaper for my country.
EDITED. I recently posted an answer to a question about whether the staff at Storebattery.sg speaks English. I said that I emailed them and they « appeared to be not English speakers ». My bad. That was another email totally unrelated to this. I don't know how to delete/edit my answer !
