Read two battery capacity figures

Copy only the two capacity figures from your Windows battery report. Use the same unit for both. No report upload is needed.

The 60,000 / 45,000 numbers are an invented worked example. Capacity percentage is not current charge percentage, remaining hours, or a replacement verdict. Values above design capacity are displayed as reported, without clamping. Blank or unavailable values are not zero. This page sends no inputs and stores none.
