You can keep a battery in the computer or in storage, depending on how you work. Keeping the battery in the computer whenever the computer is plugged into AC power charges the battery and also protects your work in case of a power outage. However, a battery in the computer slowly discharges when the computer is off and unplugged from external power.
WARNING! To reduce potential safety issues, use only the battery provided with the computer, a replacement battery provided by HP, or a compatible battery purchased from HP.
Computer battery life varies, depending on power management settings, programs running on the computer, display brightness, external devices connected to the computer, and other factors.

Most charge indicators report battery status as both a percentage and as the number of minutes of charge remaining:
●The percentage indicates the approximate amount of charge remaining in the battery.
●The time indicates the approximate running time remaining on the battery if the battery continues to provide power at the current level. For example, the time remaining will decrease when a DVD is playing and will increase when a DVD stops playing.
When a battery is charging, a lightning bolt icon may be superimposed over the battery icon on the Power Meter screen.
