• Current capacity: The battery capacity of the device in use currently.

You compare two parameters: Design capacity and Full charge capacity to know if the laptop battery has been bottled 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 bottle.

To know the exact% battery of your computer, use the following formula:

Battery capacity = ((Design capacity - Full charge capacity) / Design capacity) * 100%

Example: Design capacity = 2515 and Full charge capacity = 2098 | => The battery bottle = ((2515 - 2089) / 2515) * 100% = 16.9% Thus, the battery has been worn out nearly 17%.

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

• Capacity: The total capacity of the designed battery when shipped.
• Capacity Drop: The amount of battery is lost since you click the Start button .
• Discharge rate: Battery discharge rate.
