Just before I send my phone of for repair - Battery Question

[Villordsutch]

Is the official battery made in Korea or China. I have one from Korea which I am positive is the original and two spares in my wallet which are marked China.

Now I am 99% sure the one in the phone is the original as I marked Master and 1st on it but I want to be sure that the Korean Battery is the real one before I send the phone off for repair. Can anyone confirm this is the case please?

The batteries are usually made in China (I don't know of any Korean companies that make lithium cells). Samsung usually packages them in Korea, so they're marked Made in Korea. They're usually the same batteries.
