Battery Maintenance Guidance
Before you use your Notebook on the road, you will have to charge the battery pack. The battery pack begins
to charge as soon as the Notebook is connected to external power using the power adapter. Fully charge the
battery pack before using it for the first time. A new battery pack must completely charge before the Notebook is
disconnected from external power. It takes a few hours to fully charge the battery when the Notebook is turned
OFF. Please note the battery stops charging if the temperature is too high or the battery voltage is too high.
NOTE: Do not leave the battery pack discharged. The battery pack will discharge over time. If not
using a battery pack, it must continued to be charged every three month to extend recovery capacity
or else it may fail to charge in the future. rechargeable Li-Ion batteries require routine maintenance
and care in their use and handling. Read through below instruction and your Notebook will achieve
the maximum battery life span.
Battery Maintenance :
● Do not leave batteries unused for extended periods of time, either in the Notebook or in storage. When a
battery has been unused for 3months, check the charge status and charge or dispose of the battery as
appropriate.
● The typical estimated life of a Rechargeable Li-Ion batteries is about two to three years or300 to 500
charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully
discharged, and fully recharged again. Use a two to three year life expectancy for batteries that do not run
through complete charge cycles.
● Rechargeable Li-Ion batteries have a limited life and will gradually lose their capacity to hold a charge.
This loss of capacity is irreversible. As the battery loses capacity, the length of time it will power the
Notebook decreases.
● The run time of your battery will vary depending on the product's configuration and the applications that
you run. Routinely check the battery's charge status.
● Battery terminals must avoid contact with any metallic substance. For preventing shortage, avoid silver
coins, tinsels and any other metallic substances to contact the + and - terminals of the battery. For
example, It might happen by inserting the batteries to a coat pocket or a leather handbag with some
metallic substances mounted on it (metal buttons or zippers). There is high possibility of causing short
circuits and connection damage of the battery.
● Consider replacing the battery with a new one if you note either of the following conditions:
(1) The battery run time drops below about 80% of the original run time.
(2) The battery charge time increases significantly.
(3) If a battery is stored or otherwise unused for an extended period, be sure to follow the storage
instructions. If you do not follow the instructions, and the battery has no charge remaining when you
check it, consider it to be damaged. Do not attempt to recharge it or to use it. Replace it with a new
battery.
Charging :
The rechargeable Li-Ion batteries is recharged internally using the AC adapter. To recharge the battery,
make sure the battery is installed and the Notebook is connected to the AC adapter. The charge times will be
significantly longer if your Notebook is in use while the battery is charging. If you want to charge the battery
more quickly, put your computer into Suspend mode or turn it off while the adapter is charging the battery.
Please always follow the charging instructions provided with your Notebook.
* If you happen to leave your battery pack to go through an extended period of self-discharge, say more
than three months, the battery voltage level will become too low and needs to be Pre-Charged (to bring the
battery voltage level high enough) before it automatically resumes its normal Fast Charge. Pre-Charge may
take 30 minutes. Fast Charge usually takes 2~3 hours.
