The Lithium ion batteries are recharged inter-
nally using the AC adapter or auto/airline
adapter. To recharge a battery:
Make sure the battery to be charged is
installed in your notebook,the Det ach a bl e
Bay or the Mobile LAN Dock and
connect the AC or auto/airline adapter.
Make sure that the Battery Charging indica-
tor to the left of the Battery Level indicator
of the battery to be charged is visible on the
Status Indicator panel.
Make sure the percentage charge is shown
inside the Battery Level icon. (Figure 3-1
on page 26.)
U s i n g Y o u r L i f e B o o k L S e r i e s
When two Lithium ion batteries are installed,
the charge/discharge rate of the primary and
optional second Lithium ion batteries are the
same,as they are connected in parallel and are
both charging and/or discharging at the same
time. Since the rates are the same, one may
finish charging or discharging before the other
if they were not at the same charge level when
they were installed and/or the AC or auto/
airline adapter was connected.
There is no memory effect on the Lithium ion
batteries, which means that you do not ne ed to
discharge them completely before recharging.
A single fully discharged Lithium ion battery
will charge in approximately 4 hours when
your notebook is Off or in Suspend mode.
The charging time from fully discharged for
two Lithium ion batteries together, is approxi-
mately six (6) hours when your not ebook is Off
or in Suspend mode. Of course partially
charged batteries will not take as long to charge.
The charge times will be significantly longer if
your notebook is in use while the batteries are
charging (from approximately nine (9) hours
L i f e B o o k L S e r i e s f r o m F u j i t s u
for one battery to approximately 15 hours for
two batteries with normal operating levels).
C A U T I O N
Using heavy current devices such as LAN
cards or frequent CD-ROM/DVD access-
es may prevent charging completely.
P O I N T
You may use your Mobile LAN Dock as
a battery charging station for the optional
Second Lithium ion Battery when the
notebook is not docked in the Mobile LAN
Dock (The Mobile LAN Dock must be con-
nected to an AC or Auto/Airline Adapter).
Consult the Recharging the Batteries sec-
tion above for more information. You can-
not use the Detachable Bay as a battery
c h a rging station since it does not have a
seperate power sourc e .
