Received charged at 57%, I put in charge a few minutes and its level has reached 62%. After a day of normal use, I still have 32% !!! while the original battery is 100% charged discharged after one day (portable bought it 18 months ago)! Very happy with this purchase! Previous reviews have served me to guide my choice of purchase product (vs other batteries sold at half the price but much less effective apparently ...). In short, go for it!
