Lithium-ion battery: 7.4V, 2400mAh
Characteristics of BATTERY PACK
While the BATTERY PACK is charged or supplies power to Mobile Terminal EX, the
BATTERY PACK may be heated.
This is due to chemical reaction for generating electric energy in the BATTERY PACK
but does not indicate the BATTERY PACK is defected. If the BATTERY PACK is heated
excessively, contact your nearest maintenance representation office.
The available time of the BATTERY PACK varies depending on the usage environment
temperature.
In particular, the time of driving the BATTERY PACK is shorter at a lower temperature.
Notes on use of BATTERY PACK
The life of the BATTERY PACK is determined by the usage count and period.
It is recommended to replace the BATTERY PACK about one year after its use is
started. In successive use, the capacity begins to decrease after about 400 uses. Using
a BATTERY PACK of deteriorated characteristics due to its life continuously may cause
valuable data to be lost and/or the battery heated excessively.
Keep the BATTERY PACK in a dark cold place if it is stored for a long period. Before
using the BATTERY PACK after its storage, first charge it.
If the BATTERY PACK is not used for a period longer than a month, remove the
BATTERY PACK from Mobile Terminal EX or the charger with the remaining battery
quantity of 30% - 50%. To use the BATTERY PACK again, first charge it.
The remaining battery quantity of the BATTERY PACK decreases due to spontaneous
discharge during storage. During storage, charge the remaining battery quantity to 30% -
50% once per two or three months.
* The remaining battery 30% - 50% correspond to the status in which two of three battery
remaining character LEDs are ON.
The temperature range of battery usage is as follows:
Using the BATTERY PACK in other than the temperature range may reduce the
performance or shorten its life. Keep the available temperature range.
Available temperature range of BATTERY PACK: 5ºC - 35ºC
Before using the BATTERY PACK, read this guide carefully.
Contact your nearest maintenance representation office if you have any questions.
