Description hard to understand

Many inconsistencies in the characteristics described on the seller's page product already ordered! The one I received is black, as in the photo is silver as the original brand, then they say 1000 mah without voltage while on mine enrolled 5.6V 1500 mah for. So what to believe?
After testing over time and compared with a real brand, I can say that the battery is better than those purchased from different vendors but not as good as real. View the price is correct and recommended purchase.
