Warning when battery is fully charged

Question

I would like to get an alert (with sound) when my laptop battery is fully charged.

How can I do that?

Answer 1

Try Laptop Battery Monitor:

Laptop Battery Monitor, is an intelligent laptop battery monitoring software. It accurately displays an estimated time, until your battery will discharge, or fully charge. You no longer have to worry on how much battery power you have left, when you can have this information in hours, minutes and seconds. Features are display remaining time until the battery is fully discharged (when running on batteries), display remaining time until the battery is fully charged (when the battery is charging from the AC power supply), application runs in system tray, using minimum memory, and screen space, custom indicator colors, sound alerts when charging starts/stops, battery is full charged, or battery charge drops under a predefined percentage, automatically starts when you turn on your laptop. Works with any laptop and battery model, new or used.

Answer 2

The following script alerts you when the battery has charged to 96%, and when it falls to 5%. You can edit the line if bCharging and (iPercent > 95) Then msgbox “Battery is at ” & iPercent & “%”,vbInformation, “Battery monitor” and replace the value in (iPercent > 95) to whatever value suits you. Save the script below as Battery.vbs in your Startup folder to have it run automatically.

set oLocator = CreateObject("WbemScripting.SWbemLocator")
set oServices = oLocator.ConnectServer(".","root\wmi")
set oResults = oServices.ExecQuery("select * from batteryfullchargedcapacity")
for each oResult in oResults
iFull = oResult.FullChargedCapacity
next

while (1)
set oResults = oServices.ExecQuery("select * from batterystatus")
for each oResult in oResults
iRemaining = oResult.RemainingCapacity
bCharging = oResult.Charging
next
iPercent = ((iRemaining / iFull) * 100) mod 100
if bCharging and (iPercent > 95) Then msgbox "Battery is at " & iPercent & "%",vbInformation, "Battery monitor"
wscript.sleep 30000 ' 5 minutes
wend
