Battery is fake, despite that seller says it is "100% original". Compared to my previous Asus battery the weight is 5.5g less. The connector on the battery is visibly lower quality construction than the original. The connector is slightly skewed which makes it very difficult to connect. The printing on the battery is slightly blotchy. The battery cannot be calibrated by Accubattery app (my old Asus battery could be calibrated no problem). It is certainly not 3000mAh - more like 1500 because it holds a charge only for a few hours. Well, it does work, and it is cheap, and we all know that sellers make false claims about batteries so I will not ask for a refund.
The product corresponds exactly to the description. Unlike other replacement batteries, the actual battery capacity is shown here. The seller is fast in shipment. I recommend this seller.
