It is important to note that both charge (voltage) and capacity are factors contributing to the
battery status indicator’s display. For example, the battery status indicator displays two green
bars when a new battery has 100% capacity and has been charged to 50%. However, an
older battery that is 100% charged and only has 50% capacity also displays two green bars.
The following demonstrates this example.
This battery may either be low in capacity or low in charge as follows:
• For a new battery with 100% capacity, this symbol indicates 50% charged (low in
charge).
• For an older battery with 50% capacity, this symbol indicates 100% charged (low
in capacity).
