BatteryMon is an easy to use Windows based application
that allows users to monitor the performance of laptop batteries and uninterruptible
power supplies (UPS).
- Graphically see the charge / discharge rate
- Diagnose problem battery cells with detailed statistics
- Compare and measure your batteries performance with expected discharge
- See the critical discharge point for your batteries
- Uniquely identify battery packs for tracking purposes or system
- Log the performance of a battery for later reference
- See the status of each indivdual battery pack, when multiple batteries
are in use
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 have a problem
if their BIOS does not support ACPI. Also, some features may not be supported
by some battery types.

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
- The battery charge level is graphed in real time, along with an extrapolated
trend line and comparison trend line.
- A log file is maintained of the battery charge level and other statistics
for later analysis.
- Configurable sample period.
- A comprehensive help file.
- Detailed system and status information about each battery installed
- An interface to BurnInTest in order to evalute
battery performance, while under load.
- Mini window mode that shows multiple batteries charging/discharging
status as well as life percentage, estimated running time and more (with
adjustable transparency for Windows 2000 and later)
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.
The following information is provided for each installed battery (when
available, as not all batteries will support all of these features).
- Status: Indicates the current status of this particular battery.
e.g., "Charging", "Discharging", "Not in use".
- Manufacturer: The name of the company that manufactures the
- Device Name: This is usually the model number of the battery
pack, as defined by the manufacturer.
- Serial number: The serial number of the device as defined by
- Unique ID: An identification string, which is unique across
all battery packs.
- Time remaining: A rough estimate of how much time remains before
the battery is fully discharged.
- Battery Temperature: The temperature inside the battery pack.
- Date of manufacture: The date when the battery was manufactured.
- Type of use: Indicates if the batteries normal use is to provide
power for normal operations or if the battery is a fail safe / backup
device. (Laptop battery or UPS)
- Rechargeable: Indicates if the battery is rechargeable or not.
- Chemistry: The type of battery. Typical values are: Lead Acid,
Lithium Ion, Nickel Cadmium, Nickel Metal Hydride, Nickel Zinc, Rechargeable
- Design capacity: The theoretical capacity of the battery when
new. Measured in milliwatts hours (mWh) for most batteries.
- Full charge capacity: The battery's current fully charged capacity.
In some batteries it is possible to compare this value to the designed
capacity to estimate the battery's wear.
- Alert levels: The manufacturer's suggestion of when a "Low"
and "Warning" battery alert should occur.
- Bias: Some batteries reserve a small charge that is biased
out of the battery's Full Charge Capacity and Current Capacity values
to show "0" as the critical battery level. Critical bias is
analogous to setting a fuel gauge to show "empty" when there
are several liters of fuel left.
- Charge cycles: The count of the number of charge/discharge
cycles the battery has experienced. This provides a means to determine
the battery's wear.
- Voltage: The current battery voltage in Volts across the battery
- Charge Rate: The current rate of battery charge or discharge.
For most batteries this value will be in mWh.
