With repeated discharges and recharges, the battery's capacity will
gradually decrease. In view of this it will be noted that an often used,
older battery will not operate for as long as a new battery even when
both are fully charged.
Maximizing battery operating time
A battery's usefulness depends on how long it can supply power on a
single charge, while how long the charge lasts in a battery depends on:
Processor speed
Screen brightness
System Sleep Mode

Display power off period
Solid State Drive power off period
How often and for how long you use the Solid State Drive and external
disk(c) drives, for example, optical disc.
How much charge the battery contained to begin with.
How you use optional devices, such as a USB device, to which the
battery supplies power.
Whether you enable Sleep Mode, which can conserve battery power if
you are frequently turning the computer off and on.
Where you store your programs and data.
Whether you close the display panel when you are not using the
keyboard - closing the display saves power.
