The most important things to pay attention to are the numbers under the Active heading: these are estimates of how long your battery would accept lasted based on your laptop usage, formatted as hours, minutes, seconds.
Also, notation that in that location are two columns of Agile bombardment life estimates: At Total Charge and At Design Capacity. These are important because they estimate the difference between your laptop's battery capacity now and when it was brand-new.
