Received with delay after asking to restart the command (on that side very good communication and responsiveness of the vendor). Functional battery, much bigger than the original, must transfer the support of the original battery and after it takes place very well, autonomy is well above put in charge last night and a morning of Use j ' tjs have 3 bars so it must hold a day of intensive use even more. By cons once it gets to a bar the battery low alarm message takes forever (several hours), so do not be afraid to continue using it. Big thank you for tracking.
