#Battery Health
The **Battery Health** indicator estimates the battery's remaining full-charge capacity relative to its design capacity.
The software calculates battery health using the following formula:
Battery Health (%) = (Full Charge Capacity / Design Capacity) × 100
Using the example shown in the screenshot:
- Design Capacity: 32,560 mWh
- Full Charge Capacity: 29,733 mWh
Calculation:
29,733 / 32,560 × 100 = 91.32%
The displayed battery health is therefore approximately **91.32%**.
A higher value indicates that the reported full-charge capacity is closer to the original design capacity.
Battery health is an estimate based on reported capacity values. It is not a direct measurement of every battery cell's physical condition.
