Battery Care
Here is a quick list of Do's and Don'ts for the care of your Li-On batteries.
Do's
• When you receive a new NoteBook or Tablet PC, leave the battery to
fully charge overnight.
• Condition a new battery by using it until it is fully discharged, and
then re-charge it fully. Doing this once a month will help to accurately
calibrate your battery.
• Always ensure the battery is recharged as soon as possible after it
becomes fully discharged. A battery will be permanently damaged if
left for an extended length of time in a fully discharged state.
• Remember that a Lithium-Ion battery will slowly deteriorate; a new
battery will always perform better than one that is 6-months old.
• Remember that the battery half-life is rated for a certain total
number of charge/discharge cycles (see your User Manual or Quick
Start Guide for the rating). For example, a battery that is rated for 3
hours and 500 charge/discharge cycles, will still be considered
as within specification, even if it only lasts for 1 hour 45 minutes
after 500 charge/discharge cycles.
• Heat is the worst enemy of a battery. Allow plenty of air to circulate
around the Notebook/Tablet PC, so that the battery is kept as cool
as possible when charging and also when in use. If provided, use the
integrated 'legs' under the Notebook to raise the notebook and
improve air circulation.
• Remove the battery if stored for several months (the battery should
be at approximately 50% charge or higher).
• If you use a NoteBus or if charging your Notebooks or Tablet PCs in
a confined space, allow for adequate ventilation in order to keep the
batteries as cool as possible.
