Just what I needed

Anders on 23/06/2020 (This review has been automatically translated. Original language: swedish.)

It is not as powerful as the original battery, but keeps the charge above expectations after charging it properly and consuming it properly by the computer a couple of times. To keep in mind is to let the computer consume the battery completely (until it shuts off) and then recharge fully + a couple of hours in addition to full charge, the first two times. Do not know at the moment how long it will keep charging so well, but am really satisfied and hope the product will remain in the future. Recommended.
