Battery Health
Shows what your battery has become, not just how full it is right now.
What the battery has become, on the desktop: how full it is, and how big it still is.

About Battery Health
Every battery gets worse. It holds less than it did the day you bought the laptop, and nothing in Windows tells you how much less.
Battery Health puts that number on your desktop.
Wear, not charge
A charge reading tells you how full the battery is. It says nothing about how big the battery still is. This widget shows both, side by side: what the battery holds right now, and what it can hold at all compared to the day it left the factory.
That second figure is the one that decides whether your laptop still lasts an afternoon.
Read from the battery
The designed capacity, the full-charge capacity and the cycle count come from the battery hardware itself, the same source the built-in Windows battery report uses. Nothing is estimated and nothing is guessed.
Condition at a glance
Good, Fair, Poor or Replace, with the gauge changing color to match, so you do not have to remember what counts as a healthy percentage.
More than one battery
Some laptops and tablets carry two packs. Everything is totalled across all of them, and you can list each one separately with the capacity that tells them apart.
Light, dark, or frosted so the desktop shows through. Any size. Sits on the wallpaper or above your windows.
No account needed. No sign-in needed. Nothing leaves your PC unless you send feedback or turn on backup. No ads.
Built for Windows 11, and at home on Windows 10.
