Interpreting a Battery Health Report: Full Charge Capacity Exceeds Design Capacity

[RCallas]

Before purchasing a replacement battery for my PC, I ran a Battery Health Report because the battery on my laptop will no longer power it for more than a few minutes.



My question about the report relates to the "Battery Capacity History" section. For my PC the Full Charge Capacity greatly exceeded the Design Capacity and values for both varied greatly over the reporting period. At the first date listed the Full Charge Capacity equaled 2,741 mWh and Design Capacity equaled 4,400 mWh. On the last date reported (about 3 years later) the Full Charge Capacity equaled 675,235 mWh and Design Capacity equaled 48,840 mWh.



I would be grateful for anyone's help in interpreting what this report indicates relative to the health of my PC's battery and how the Design Capacity change can over time and sometimes greatly be exceeded by the Full Charge Capacity.



Thanks
