3-4 Chapter 3: Getting Started
For safety reasons, DO NOT throw the battery in
fire, DO NOT short circuit the contacts, and DO NOT
disassemble the battery. If there is any abnormal
operation or damage to the battery pack caused
by impact, turn OFF the Eee PC and contact an
authorized service center.
Battery Care
The Eee PC’s battery pack, like all rechargeable batteries, has a limit
on the number times it can be recharged. The battery pack’s useful
life will depend on your environment temperature, humidity, and
how your Eee PC is used. It is ideal that the battery be used in a
temperature range between 5˚C and 35˚C (41˚F and 95˚F). You
must also take into account that the Eee PC’s internal temperature
is higher than the outside temperature. Any temperatures above or
below this range will shorten the life of the battery. But in any case,
the battery pack’s usage time will eventually decrease and a new
battery pack must be purchased from an authorized dealer for this
Eee PC. Because batteries also have a shelf life, it is not recommended
to buy extras for storing.
