Batteries, given their chemical nature, are prone to wear corrosion, leakage and outright failure due to events like short circuits and lightning strikes. Thus it is important to be able to identify and monitor their performance. With BatteryMon, monitoring the state of your battery has never been easier. BatteryMon is an easy to use Windows program that allows the monitoring of laptop computer batteries and uninterruptible power supplies (UPS). Graphically see the battery charge / discharge rate, diagnose problem battery cells, compare your batteries performance with expected discharge rates and see the status of each individual battery pack (when multiple batteries are in use).

Batteries and BIOS must comply with the Windows, Advanced Configuration and Power Interface (ACPI) specification in order for BatteryMon to work correctly. More than 20 statistics are provided including voltage levels, battery chemistry, serial number, design capacity, charge cycles and charge rates.
