Batteries, given their chemical nature, are prone to wear, corrosion, leakage and outright failure due to events like short circuits and lightning strikes. Given their propensity to fail and to have decreased performance over time, it is important to be able to identify and monitor their performance. With BatteryMon, monitoring the state of your laptop battery or UPS has never been easier. BatteryMon has the following features:

Typical users include portable computer repair centers, system integrators, server administrators who must manage UPSes and, home users wanting to test their battery or UPS.


Any laptop battery or UPS that complies with the Windows, Advanced Configuration and Power Interface (ACPI) specification should be able to report information to BatteryMon. Older PCs may also have a problem if their BIOS does not support ACPI. Some features may not be supported by some battery types, typically they will report only partial information in this case. It has been also been noted that several UPS manufacturers are not providing compliant device drivers.

Status Information

The following information is provided for each installed battery (when available, as not all batteries will support all of these features).


We are offering a free upgrade to BatteryMon 2.1 to our existing BatteryMon customers. However, as of release V2.1 build 1008 no license key is required to use the software. So existing customers can just download and use, without restriction, the current release.
