Battery life is determined by the number of recharging cycles the battery can support. Since this is a refurbished model, we recommend you contact Best Buy directly to see if the battery was replaced during the refurbishment. If not, how old is the computer?

That will depend on the programs you will be using with this computer. We recommend you check with the specific software publisher's web sites, of the programs you will be using, for their compatibility with Windows 10 S-Mode 64-bit operating system (Windows 10 S-Mode provides added security by only allowing APPs available ( and therefore certified by Microsoft) at the Microsoft Store. If you don't need the added security or you need to install APPs not available at the Microsoft Store, you can switch to standard Windows 10 Home 64-bit Operating System, at no additional cost.) and the minimum/recommended hardware requirements (Is a Graphics card required, the processor speed and the minimum required system RAM and the minimum available hard drive space) to run their program, then compare those requirements to this system's configuration.

It is good for Microsoft Office and light internet browsing. This model ships with Windows 10 S-Mode Operating System.
