2-2 User’s Manual
Do not expose battery packs to temperatures below 0ºC (32ºF)
or above 60ºC (140ºF). This may adversely affect the battery
pack.
If the notebook is to be stored for more than two weeks, we
suggest that you remove the battery pack. In suspend mode or
power-off condition, the battery power (from a fully-charged
battery pack) depletes in one month.
Battery Pack Characteristics
The battery pack has the following characteristics:
• Battery pack self-discharge Battery packs self-discharge slowly, which
may result in a low battery power condition after being stored for
weeks.
• Memory effect This is a phenomenon wherein charging finishes in
one-third the normal charge time. This leaves the battery pack not
fully charged. This situation can usually be improved by conditioning
the battery pack twice a month. Please refer to section 2.3.2 for details
on how to condition the battery pack.
