I\u2019ll also include built-in methods so you can decide whether to install something new or use what\u2019s already there.\n\n---\n\n## \ud83d\udd27 Built-in Options in Windows 11\n\nYou don\u2019t always need third-party software\u2014Windows 11 includes native settings for low battery alerts and thresholds.\n\n- Go to **Control Panel \u2192 Hardware and Sound \u2192 Power Options \u2192 Change plan settings \u2192 Change advanced power settings**.  \n  There, you can expand **Battery \u2192 Low Battery Level** to pick a percentage and enable **Low Battery Notification** (\u201cOn Battery\u201d and \u201cPlugged In\u201d). ([howtogeek.com](https://www.howtogeek.com/set-custom-low-battery-alerts-windows-11/?utm_source=openai))  \n- If you want more visible alerts (toast notifications), you can use Task Scheduler + PowerShell scripts to trigger custom notifications when battery falls below a threshold. ([howtogeek.com](https://www.howtogeek.com/set-custom-low-battery-alerts-windows-11/?utm_source=openai))\n\n---\n\n## \ud83e\uddf0 Freeware / Open Source Tools\n\nThese tools let you get more flexibility\u2014custom thresholds, sounds, better UI, background monitoring, etc.\n\n| Tool | Key Features | Pros & Considerations |\n|---|---|---|\n| **BatteryNotifier** *(by Sandip124)* | Tray app with custom full/low battery thresholds; custom alerts; battery health dashboard; dark/light themes. Runs on Windows, macOS, Linux. Fully open-source (MIT), no telemetry. ([batterynotifier.com](https://www.batterynotifier.com/?utm_source=openai)) | Very feature-rich; has visual polish. Good if you want advanced alerts & health tracking. |\n| **BatteryInfoView** *(NirSoft)* | Portable utility (no install); detailed battery data (charge %, health, voltage, discharge/charge rate); logs data. ([batteryinfoview.com](https://batteryinfoview.com/?utm_source=openai)) | Doesn\u2019t always include *notification popups* by itself\u2014but great for diagnostics & monitoring. |\n| **BatteryMaster** | Real-time metrics: wear level, charging/discharging power, voltage; logs usage history. Optionally display in tray. ([batterymaster.weero.net](https://batterymaster.weero.net/?utm_source=openai)) | More comprehensive battery info; might be overkill if all you want is a low battery alert. |\n| **BATExpert** | Shows estimated time until battery reaches low level; basic info like current usage, temperature. Freeware. ([techspot.com](https://www.techspot.com/downloads/6392-batexpert.html?utm_source=openai)) | Useful snapshot view; fewer customizable alerts. |\n| **StarTray Battery** | Displays battery percentage/icon in system tray; configurable themes, portable. ([github.com](https://github.com/justinnas/StarTray-Battery?utm_source=openai)) | Mostly visual; doesn\u2019t automatically alert beyond showing status. |\n\n---\n\n## \ud83c\udfaf What I Recommend\n\nIf you want a \ud83c\udfaf simple but powerful solution for **low battery warnings**, I\u2019d suggest using **BatteryNotifier**. It gives you:\n\n- Custom % thresholds for low and full battery alerts  \n- Audible/visual notifications  \n- Health stats etc.  \n\nIf even that feels like overkill and you just want something small and free, use a PowerShell script + Task Scheduler (from the built-in method above) to show a toast notification when battery falls under, say, 20%.\n\n---\n\n## \ud83d\udee0\ufe0f Setup Tips & Extra Tricks\n\n- If using **BatteryNotifier**, explore its settings: sound types, thresholds, startup behavior, etc.  \n- For **BatteryInfoView**, use its export or log feature to track battery degradation over time.  \n- If doing the Task Scheduler route: set it to run every few minutes or on battery state change, depending on how responsive you need it.\n\n---\n\nIf you like, I can send you download links & step-by-step setup instructions for one of these tools (e.g. BatteryNotifier) to get you up and running fast. Want that?"
