Checking the Battery Level
The battery level cannot be measured physically. Any reading on a battery
meter or gauge is only an estimation. This, however, could be less than
accurate due to factors such as temperature and a long period of storage. If
the difference between the displayed battery level and the actual operating
time is too large, initialize the battery pack as described earlier in this
chapter to correct the problem.
By Operating System
Some operating systems, such as Windows, display a battery meter that
indicates the battery level.
By Gas Gauge
A “gas gauge” on the battery pack itself also indicates estimated battery
charge. If the battery pack is not installed and you want to check the
level of the battery, you can do so by noting the number of lighted green
segments. These indicate the relative percentage of the battery charge.
The battery pack is fully discharged when a lighted green segment no
longer appears.
