Getting Started
Getting the best out of your battery pack
Use the approved Battery Pack N14 for a FOMA terminal.
If you use a FOMA terminal overseas, take the FOMA AC Adapter for Global Use 01 with you. Before using the
FOMA AC Adapter for Global Use 01, check the voltage available in a country or area you will stay.

Battery life
a
Batteries have a limited service life. Like all rechargeable batteries, the amount of usable time decreases every
time the battery is recharged.
a
When a fully charged battery pack only lasts half as long as when it was new, it is time to replace it with a new one.
a
In general, the service life of a battery pack is about one year. It may be shortened depending on the frequency of use.
■
Charging
a
For details, refer to the manuals for FOMA AC Adapter 01 (optional) and FOMA DC Adapter 01 (optional).
a
Attach the battery pack to a FOMA terminal to charge the battery.
a
You can receive calls while charging if a FOMA terminal is turned on. However, the battery level
will fall during calls and the time required for charging will increase. Charging time will also
increase if “Charging” in “Backlight” is set to “All time ON”.
a
When plugging in or out the connector, do it slowly and securely not to apply excessive force.
a
When you make a call or perform packet communication in a high-temperature environment, the
FOMA terminal’s temperature may rise and the charging may be stopped. In this case, stop a
running function and wait for the temperature to fall before you retry charging.
■
Do not charge the battery pack for a long period of time (several days) with a FOMA terminal turned
on
a
If you charge the battery pack for a long period of time with a FOMA terminal turned on, power to
the FOMA terminal will be supplied from the battery pack once charging ends. As a result, you will
only be able to use the FOMA terminal for a short period of time and the low voltage alarm may
sound immediately. In this case, recharge the battery pack correctly. Disconnect a FOMA terminal
from the AC adapter (or desktop holder) or DC adapter and then attach it again for recharging.
■
Battery duration (The battery duration varies depending on the charging time or deterioration of the battery)
a
Continuous talk time is an estimate of the talk time at maximum power when radio reception is
normal.
a
Continuous standby time is an estimate of the standby time when the FOMA terminal is folded
and remains within an area where radio reception is normal. In certain circumstances, talk (or
communications) and standby times may drop to as low as half the times shown due to the
battery charge, function settings, temperature, or radio reception in the area (weak or no
reception). Talk (or communications) and standby times will be less when you use i-mode.
These times will also be less when you compose an i-mode message, run downloaded i-
α
ppli,
launch the i-
α
ppli display or play music even without making calls or using i-mode.
a
Continuous standby time for stationary is an average estimate of the standby time when the
FOMA terminal is folded and remains within an area where radio reception is normal.
a
Continuous standby time in transit is an average estimate of the standby time in “stationary”, “in
transit” and “out of range” states when the FOMA terminal is folded and remains within an area
where radio reception is normal.
a
Talk (or communications) and standby times will also be less when you insert a microSD
memory card, run data communication or multi access, or use the camera or light.
To protect the environment, take used battery packs to NTT DoCoMo, the
agency, the recycle shop, etc.
Continuous talk time Continuous standby time
Voice communications: Approx. 190 min.
Videophone: Approx. 100 min.
Stationary: Approx. 680 hours
In transit: Approx. 500 hours
NOTE
e
If the battery runs out or the battery pack is removed, you cannot save images or movies.
