To ensure that the battery maintains its maximum capacity,
operate the computer on battery power at least once a month. The

let the battery fully discharge each time. However, for better
accuracy of the battery meter, it is helpful to fully discharge the
battery periodically. Please see

on AC power, either through an AC adaptor or a port replicator (if
applicable to your system), for an extended period (more than a
month), the battery may fail to retain a charge. This may shorten the
life of the battery, and may cause the battery meter to be inaccurate.

The computer also has an internal real-time-clock (RTC) battery.
The RTC battery powers the RTC memory that stores your system
configuration settings and the current time and date information. It
maintains this information for up to a month while the computer is
turned off.
