Overview

The main window is divided into several sections:

• Battery Information: Displays battery identification, technical specifications, capacity values, voltage, and power status.
• Battery Health: Shows the calculated battery health percentage and relative capacity loss.
• Battery Capacity Indicator: Displays the current charge level relative to the reported full charge capacity.
• Power Source: Indicates the reported power source status.
• Current Capacity: Shows the remaining battery energy in milliwatt-hours (mWh).
• Charging/Discharging Rate: Displays the reported battery power rate in milliwatts (mW).
• Capacity Bar: Provides a visual representation of the current battery capacity.
• Anomaly Status: Displays the result of the software's available anomaly checks.
• Show R.A.W. Value: Opens a separate window containing low-level device information and raw response data.

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

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.

Relative Capacity Lost

Relative Capacity Lost represents the percentage of the original design capacity that is no longer available according to the reported full-charge capacity.

Formula:

Capacity Lost (%) = 100% − Battery Health (%)

Example:

100% − 91.32% = 8.68%

The software therefore displays:

- Battery Health: 91.32%
- Relative Capacity Lost: 8.68%

This calculation describes capacity reduction relative to the design specification. It does not necessarily indicate an immediate battery fault.
