4) Special reminders:
Because of the intrinsic properties of lithium-ion batteries, please note the following:
a. When disposing of a defective or old battery, please apply adhesive tape to the terminals and
dispose of the battery according to local regulations.
b. In order to prolong the service life of the battery, please do not charge the battery frequently in
an intermittent way. The number of charging cycles has significant influence on the service life
of the battery.
c. Charging will cause slight heating, which is considered normal.
d. If the temperature in the charging environment is too high, the battery will not become fully
charged. Please do not charge the battery at an excessively high ambient temperature. It is
preferred to charge the battery at an ambient temperature of 10-30°C.
e. In normal storage, the capacity of the lithium-ion battery will decrease naturally over time. As a
result, the playing time will be shortened.
f. The capacity of the lithium-ion battery will decrease gradually as the number of charging cycles
increases. As a result, the playing time will be shortened.
g. The capacity of the lithium-ion battery will decrease gradually along with a drop in ambient
temperature. As a result, the playing time will be shortened.
The aforementioned consumptions are normal consumptions of the lithium-ion battery. It is
recommended that the user charge the battery when it is nearly discharged in order to extend the
service life of the lithium-ion battery.
