Temperature plays an
important role in recharging
your battery. To gain maximum
capacity, allow both the battery
and your Notebook to cool to
20° C (68°F), which is room
temperature, before recharging
the battery.
You may store your battery
within the following
temperature range:
0° C to 45° C (32° F to 113° F).
To extend its operating life,
store the battery in a cool dry
place.
“Government Approvals”
section of the Safety and
Comfort Guide for more
information on recycling.
Refer to the following storage requirements.
NiMH Battery – If your Notebook uses a NiMH (nickel-metal-
hydride) battery and you will not be using your Notebook for a
long period of time (more than two weeks):
• Use your Notebook until the battery is drained completely.
• Remove the battery from your Notebook and store
it separately.
Li-Ion Battery – If your Notebook uses a Li-Ion (lithium-ion)
battery and you will not be using your Notebook for a long
period of time (more than two weeks):
• Use your Notebook until the battery is drained to 50 percent.
• Remove the battery and store it separately.
Recycling the Battery
In North America, dispose of
nickel-metal-hydride or lithium-ion
batteries by taking advantage of
the Compaq battery recycling
program. You will be provided
with a postage-paid battery pack
envelope pre-addressed to a
reclamation facility where the
metals are recycled.
Do not dispose of batteries with general household waste.
Dispose of or recycle them by using a public collection system
or returning them to Compaq, your authorised Compaq partners,
or their agents.
