Excellent! Notebook working from 3 to 3,5 hours from battery!
I've ordered one of these batteries before (although I think from a different vendor last time). Either way, this is a GOOD quality laptop battery. The first one I ordered (January of 2016), lasted a solid 3 whole years! It was only in July (of this year 2019), that it finally started to show very visible signs of not holding a charge any longer and knew it was time to replace that first one. So I ordered another, got it, put it into the laptop, and by the next hour or so, it was fully charged and completely ready to go again!
