Is my battery original?

I bought a new battery for inspiron 14R (N4010) from local store and the battery being delivered today. But after I checked the battery, I think it is not an original one.

1. The font size used is different

2. The original one has : battery cell made in korea assembled in China. The one that I just received: battery cell made in Japan assembled in China. The position of the writing is also different

3. The size of logos on the battery is also different. And the position of two logos is switched.

4. One logo has different color

5. The side shape of the battery is slightly different

6. The original one writes 4.14 Ah. The other one 4.2 Ah

7. The original one writes: To purchase Dell batteries: www. dell.com. The other one:  To purchase Dellbatteries: www. dell.com (no space between dell and batteries)

From the start, I told that I want to buy an original one but this is the one that being sent by the store. Did I just buy a fake one?
