When the battery of your Windows 10 laptop or tablet reaches the low level, Windows alerts you by displaying a notification on the screen. However, Windows 10 doesn’t alert you when the battery is fully (100%) charged.

Many users believe that leaving your laptop or tablet plugged in and charging all the time reduces the lifespan of the battery. A quick web search reveals that leaving your laptop plugged is okay and might not reduce battery lifespan significantly. That said, experts suggest one should keep a watch on battery’s temperature when plugged in for a long time. If the battery is overheating, it’s a good idea to unplug your laptop.

Most of the OEMs include a power manager these days to avoid overcharging batteries. A power manager software usually displays a notification when the battery reaches 100% level and stops the battery from overcharging.

Method 1 of 2

Get full battery alert using Battery Alarm Free

Battery Alarm Free is an app designed to help you get notified when the laptop or tablet battery reaches the maximum level. You can configure the app to show a notification when the battery reaches a specific limit as well. For instance, you can configure it to show the full battery notification when the battery is 95%. Besides that, the app shows some vital information about the battery.

Method 2 of 2

Get full battery alert in Windows 10 using Visual Basic Script

If there is no dedicated power manager software on your Windows 10 laptop or tablet and you want to get a notification when the battery is fully (100%) charged, you can use small workaround offered by John Howard to get full battery notification on Windows 10.

Before you begin reading the workaround, let us tell you that the below script might not work accurately if you have multiple batteries. For instance, on my ThinkPad T450s, which has two batteries, the script displays full battery notification only when the second battery reaches 100% level.

Complete the given below directions without any deviations to get full battery notification in Windows 10.

Step 1: Download the FullBattery.zip file from here. Extract the zip file (right-click, click Extract all, select a location, and then click Extract) content to desktop to get FullBattery.vbs file. The credit for the script file goes to John Howard. We have only changed the script to get a notification when the battery level reaches 99% instead of the default 95%. If you’re wondering why 99% instead of 100%, for some reason the script doesn’t show the percentage when the battery level reaches.

NOTE: You may edit the script to get notification for battery level anything between zero and hundred. To edit, right-click on the script, click Open with, click Notepad, change the 100% value to a number between zero and hundred. Don’t forget to save the changes!

Step 2: To enable full battery notification, simply double-click on FullBattery.vbs file once. Note that you will not see any notification or any window upon running the VBS script. Also, make sure you don’t launch the script multiple times as multiple instances of the script mean multiple notifications!

You need to manually launch the FullBattery.vbs file each time you restart your PC. If you want to avoid that, you need to make the script run at startup (see how to start programs/apps/scripts at startup) by adding a shortcut of the script to the Startup folder. To automatically load the script with Windows 10, follow directions in next three steps.

Step 3: Create a shortcut of the script by right-clicking on FullBattery.vbs file and then clicking Create shortcut option.

Step 4: Open the Run command box using Windows logo + R hotkey. In the command field, type Shell:startup, and then press Enter to open the Startup folder.

Step 5: Finally, copy and paste the FullBattery shortcut that you created in Step 3 into the Startup folder. That all! From now onwards, the FullBattery.vbs script will load with Windows 10 and displays a notification with sound when the battery level reaches 100%.

Hope this helps!
