How To Enable Full Battery Notifications in Windows 10

📅
🕑 4 minuten lezen

When your Windows 10 laptop or tablet’s battery hits a low level, you get a notification popping up to warn you. That’s pretty standard. But, strangely, Windows doesn’t alert you when the battery reaches a full 100% charge. Kind of weird, but that’s how it is. If you’ve ever left your device plugged in for hours after it’s full, you probably wonder why there’s no alert, especially since most OEMs include a power management tool that’s supposed to handle overcharging. Yet, sometimes those just don’t do enough or don’t alert at the exact right moment. So, if you want to be in the know when your battery’s maxed out, here are a couple of ways to set that up — some more reliable than others.

Most solutions involve playing around with apps or scripts because, out of the box, Windows really doesn’t care about your battery’s full charge state. If you want a solid notification, you gotta tweak things a bit. Here’s what worked out in practice — not foolproof, but better than nothing.

How to Fix or Get a Full Battery Alert in Windows 10

Method 1: Get Notified with Battery Alarm Free

This app is kinda simple but does the job. It lets you set a custom percentage — say, 95% or even 99% if your device can’t handle the last 1% — and then alerts you. Why it helps: it fills in that gap Windows hides, especially if your OEM doesn’t give a good notification when fully charged. When it applies: if you’re sick of guessing when your battery hits the max, this app will give you a heads up. Expect a popup and possibly a sound. Usually, it’s pretty reliable, just sometimes needs a bit of fine-tuning in the settings.

Download Battery Alarm Free from its official site or GitHub (a lot of these free tools are on GitHub now, just search for Battery Alarm Free).Install, fire it up, and set your preferred charge level. On one setup it worked perfectly, on another it took a couple of tries, mainly because of permissions or app conflicts. Still, better than no notification at all.

Method 2: Use a Visual Basic Script to Detect Full Battery

This one is more of a DIY workaround and not 100% perfect, especially if you’ve got a multi-battery setup (like some Lenovo or ThinkPads with dual batteries).Basically, there’s a small VBS script written by John Howard that can monitor your battery percentage and pop a notification. The reason it helps: it’s a free, programmable way to get alerts when Windows’ native tools fall short. When to use: if you’re comfortable with scripts and want a low-tech solution without extra software. What to expect: a simple notification with sound when your battery hits a certain level (say, 99%).Sometimes, it takes a few tries to get the script working smoothly, and on some laptops, it might only trigger when the second battery hits full — kinda weird but what can you do.

Here’s a quick rundown on making this work:

  • Download the FullBattery.zip from a trusted source or the official blog linked here: John Howard’s blog.
  • Extract the ZIP file to your desktop — right-click > Extract All, choose a folder.
  • Use a tool like 7-Zip or the Windows built-in extractor if needed.
  • Once extracted, double-click the FullBattery.vbs to run it. No pop-up — it just sits there waiting. Make sure not to run it multiple times, or you’ll get spammed with multiple notifications.

To keep this working after a reboot (because, of course, Windows has to make it harder than necessary), you need to add it to your startup folder:

  1. Right-click on FullBattery.vbs and select Create shortcut.
  2. Press Windows + R to open the Run box, type shell:startup, then press Enter. This opens your Startup folder.
  3. Copy and paste that shortcut into the Startup folder. Done. Now, it’ll automatically run whenever Windows starts, giving you a notification when your battery hits full.

Again, not perfect for all setups but works on most simple single-battery laptops. Just remember: this is a bit of a hack, so expect some quirks, especially with multiple batteries or unusual hardware. Also, you need to launch that script manually or set it to run at startup for it to be effective. On some machines, it took a reboot or two before it started working consistently.

Hopefully, this gets one update moving and helps you stay on top of your battery health without relying entirely on OEM features or luck. The script is lightweight and pretty unobtrusive, so might be worth a shot.
