I miss a step back, because what ultimately interests me is the life ... Delivery was fast, but the packaging was more than limit ... All batteries are not to arrive at the customer's status, but mine was untouched by luck! Compatibility smoothly on my Asus, and normal load without overheating. After 6 months it's disillusionment: my battery did not exceed more than a few weeks its 6 months warranty! It is already HS !!!
