Heat damage to your Lithium ion battery
• Extended exposure to heat will have a negative impact on your battery.
Do not expose your notebook to exces sive heat such as leaving it in
the car on a hot summer day. If you are near an outlet and playing
a graphics-intensive game, it is recommended that you remove the
battery from the unit to avoid exposing it to excessive heat.
Discharging your battery
• Full battery discharges (to unit shutdown or 0%) should be avoided. It
is recommended that batteries only be partially discharged to levels of
20-30% before recharging.
Prolonged storage
• If your notebook isn't going to be used for a while, you should remove
its Lithium ion battery. To store a battery for long periods of time, its
charge capacity should be around 40% and store it in a cool dry place.
Purchasing a replacement battery
• Only purchase a replacement battery from Fujitsu. Ensure that you
purchase a battery that is specifically designed for your model
computer. It is recommended that you purchase a replacement battery
only when the current battery has noticeably degraded; unused
batteries will still suffer degradation when stored.
