How to check laptop battery with BatteryMon

* Note: If you do not have BatteryMon software, please download the latest version of BatteryMon 2.1 using the download link below.

Step 1: Access the BatteryMon 2.1 build 1010 download link here.
Step 2: Install the software on the Laptop. Immediately BatteryMon will automatically open. At the main interface, click on  the battery icon  in the upper left of the window to open the detailed battery information panel. Here, you are interested in the following 3 items:

- Design capacity: Original designed battery capacity announced by the manufacturer.
- Full charge capacity: Actual battery capacity after full charge.
- Current capacity: Current battery capacity of the device in use.

Step 3: You compare the two parameters  Design capacity and Full charge capacity to know whether the laptop battery is worn out or not. As shown below, the battery capacity is still 2515 mAh, so it can be said that the computer battery in the example has not been depleted.

- In addition, to know the exact % of your computer's battery capacity, use the following formula:  Battery capacity = ((Design capacity - Full charge capacity) / Design capacity) * 100%

+ For example: Design capacity = 2515 and Full charge capacity = 2098|
=> Battery wear = ((2515 - 2089)/2515)*100% = 16.9% (Thus, the battery has been worn out by nearly 17%). If the battery level is less than 20%, your laptop battery is still good. In case the battery level is greater than 20%, you should think about replacing a new battery for your laptop.

- Besides the feature of checking battery health and providing necessary information about the battery, BatteryMon also allows you to monitor the charge/discharge level of your laptop's battery in real time through the battery status graph by clicking Click the Start button in the lower left corner of the program's main interface or select Run > Start to start the monitoring tool.

- A graph of the battery status in real time will then appear. Based on the discharge level when the computer is not plugged in, BatteryMon will calculate the remaining time of the battery before it is completely depleted. Here you can see the battery status, % battery remaining, how much time has passed since tracking started, and more.

- The black discharge level indicator helps you determine whether the battery is good or not. A good performance battery will have a very smooth discharge path, the time for each discharge is probably the same. If the discharge line drops suddenly, there is no doubt that your battery has a problem.

- In addition to the information obtained from the chart, you will also get information from the following 3 parameters above the chart:

+ Capacity: Total designed battery capacity when shipped.
+ Capacity Drop: The amount of battery lost since you pressed the Start button.
+ Discharge rate: Battery discharge rate.
