The specs have this to say about the battery Battery 68‑watt‑hour battery Up to 11 hours battery https://kde.slimbook.es/specs/ https://kde.slimbook.es/specs/ About the build quality, can't say about this model but I do have KDE Slimbook I from 2017, if I remember correctly, and it was decent. Well certainly good enough to last these 7/8 years
