Rechargeable Li-ion Battery
Characteristics
14
Understanding the properties of the
rechargeable Li-ion battery will allow you to
optimize its usage.
 Using or storing the rechargeable Li-ion
battery in a location exposed to high or low
temperatures may accelerate its
deterioration. In particular, using a
rechargeable Li-ion battery with a high
charge (charged 90% or more) in a
location exposed to high temperatures will
considerably accelerate battery
deterioration.
 Using the printer while the rechargeable
Li-ion battery is installed and being
charged may accelerate the battery’s
deterioration. When using the printer with
the rechargeable Li-ion battery installed,
disconnect the AC adapter.
 If the printer will not be used for a long
period of time, remove the rechargeable
Li-ion battery from the printer when its
charge is 50% or less, and then store the
battery in a cool place away from direct
sunlight.
 If the rechargeable Li-ion battery will not
be used for a long period of time, we
recommend charging it every 6 months.
 For other precautions, refer to the
instruction manual included with the
rechargeable Li-ion battery.
