Can this browser page test battery health?
No. A browser cannot reliably access designed capacity, full-charge capacity or cycle count.
Why is battery status unavailable?
Many browsers restrict the Battery Status API for privacy. It does not mean that the physical battery has failed.
Does the desktop app work on every battery?
It reports only information exposed by Windows and the battery hardware. Unsupported fields stay unavailable.
