Battery Alarm

Battery Alarm is a very simple Windows application designed to notify when whenever their laptops are running low on battery.

It comes packed with a basic set of options that can be easily configured by all types of users, even those inexperienced with computer software.

The installer runs quickly and without any issues. Once started, Battery Alarm creates an icon in the system tray area, and pops up a balloon the moment the battery drops below 8%.

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. There are no other notable configuration settings available.

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. No error dialogs were shown in our testing, and the tool did not hang, crash or pop up error dialogs.

To sum it up, Battery Alarm offers a very simple solution to receiving audio and video alerts whenever the laptop battery is running low, featuring support for powerful, yet intuitive configuration options.
