Battery Pack Operating Time
This section covers the following information concerning battery pack operating time:
Increasing battery pack operating time
Conditioning a battery pack
Disposing of a used battery pack
Increasing Battery Pack Operating Time
Battery pack operating time differs depending on several variables. To avoid unnecessary replacement, consider the
following variables when determining how long a charged battery pack should last:
Power management settings
Hardware configuration
Software applications
Installed options
Display brightness
Hard drive usage
Changes in operating temperature
Type and number of installed PC Cards
NOTE:
The power consumption requirements for PC Cards vary widely. Some cards drain the battery
pack very rapidly.
Battery pack operating time can be increased by as much as 50 percent by controlling the energy required by the
computer and the energy stored in the battery pack.
Minimizing the Energy Required
file:///C|/download/www.compaq.com/athome/support/msgs/1900XL/6battery.html (1 of 3)6/27/2004 11:45:55 AM
Battery Pack Operations
To minimize the energy required by the computer, follow these steps:
Set the power conservation levels in the Power Management utility to Maximum .
Customize the timeout value to work more efficiently with the applications. The amount of battery
life depends on the values selected.
Maximizing the Energy Stored
To maximize the energy stored in the battery pack, follow these guidelines:
Condition the battery pack at least every 30 days to improve overall battery performance.
Keep a battery pack in the computer when using it with AC power to supply the battery pack with a
constant trickle charge.
Store the battery pack in a cool, dry place when not in use.
Conditioning a Battery Pack
CAUTION: To avoid a loss of data, ensure that all data is saved before discharging a battery pack.
To condition a battery pack, complete the following steps:
1. Plug in the AC adapter and allow the battery to charge until the fast charge arrow on the display
disappears. Your battery gauge may read 100 percent for a period of time before the arrow
disappears. Do not unplug the AC adapter until the arrow disappears.
2. Unplug the AC adapter and allow the battery to drain until the computer reaches hibernation and
turns itself off.
CAUTION: Do not plug the AC adapter during this process or you will need to restart with step number
1. You may use the computer while the battery is draining.
3. Your battery is re-conditioned.
4. Plug in the AC adapter and begin using the computer.
The table below shows battery pack charge times by model.
Battery Charge Time
Computer On Line Off Line
Li ion Battery Pack 4.5 hours premature termination 2:50 hr
Disposing of a Used Battery Pack
file:///C|/download/www.compaq.com/athome/support/msgs/1900XL/6battery.html (2 of 3)6/27/2004 11:45:55 AM
Battery Pack Operations
In the interest of safeguarding our environment. Compaq Computer Corporation recommends that nickel metal
hydride (NiMH) and lithium ion (Li ion) battery packs be recycled. Battery packs should be handled in accordance with
country, state, province, or local regulations.
CAUTION: Never attempt to open or service a battery pack. Opening a battery pack not only damages
the pack and makes it unusable, but also expose potentially harmful battery components.
