It also shows you how much power is available in the battery when charged.

The load fraction refers to the continuous load capacity (calculated in watts) drawn by the electronic devices or the car audio system. For example, If the audio system has a 300-watt capacity, and the preserved load of the battery is 70, the result will be “10 x 70 divided by 300 = 2.33-hours.”
