It comes packed with a basic set of options that can be easily configured and sits in the system tray unnoticed.
Once started, BatteryAlarm creates an icon in the system tray area, and pops up a balloon the moment the battery drops below 10%.
Until then it shows the current power level and remaining power life. The configuration panel can be accessed from the right-click menu.
The graphical notification is backed by sound, and Battery Alarm uses a preset file. It lets users swap it with any other audio track, as long as it has the WAV format.
It is possible to change the percentage level for triggering the low-level battery alarm, make the tool repeat the notification at a regular time interval (in minutes), as well as disable the message when the battery is fully charged.
Battery Alarm has a good refresh rate, shows accurate data on the battery life, and uses a minimal amount of CPU and RAM, so it does not affect the PC's overall performance.
