Important Notes on Using a Battery Pack
Recharging and Discharging
•
Recharging will not start if the battery’s temperature is below 0
°
C (32
°
F) or
above 45
°
C (113
°
F) for NiMH batteries and 40
°
C (104
°
F) for Li-ion
batteries. Also, during recharging, the recharging will stop if the battery’s
temperature gets above 60
°
C (140
°
F). To avoid problems caused by
temperatures, make sure the battery is not too hot before you begin to
recharge or discharge the battery. Follow these general guidelines:
−
When the battery is fully discharged, allow a 30-minute interval before
you connect the AC adapter to recharge the battery.
−
When the battery is being recharged, keep the notebook power o ff and
wait until it is fully recharged.
−
When the battery is fully charged, disconnect the AC adapter and
allow a 30-minute interval before you begin to use the battery power.
•
During recharging, do not disconnect the AC adapter before the battery has
been fully charged; otherwise you will get a prematurely charged battery.
•
After the notebook has been fully recharged, do not immediately disconnect
and reconnect the AC adapter to charge it again. Doing so may damage the
battery.
•
Do not leave the battery completely discharged for too long as this may
affect the battery’s performance.
Problem Solving
•
If the difference between the actual operating time of a battery and the
expected operating time is too large, you can fully discharge and recharge
the battery several times to solve the problem.
