Battery Information
Battery on First Use
Since batteries leave factory without a fully charging, please
charge the new battery before using. Under normal
circumstances, the battery on first use needs 5 hours of charging.
The first three times of fully charging and discharging provides
batteries the best capacity. When you find electricity shortage,
need to recharge or replace it.
Types of Compatible Battery
Please use the specific battery, it may cause
explosion using other batteries, resulting in bodily injury.
Safety Precautions
1. Do not throw the battery into the fire.
2. Do not dispose the batteries as household wastes, and it
must be collected and treated properly.
3. Do not rip off shell from the battery without permission.
Notes:
1. When charing, the temperature should be between 5ć~40ć,
otherwise it may cause the leakage or even damage the battery.
2. Please shut down the transceiver while charging is ongoing
will affect the normal battery charging.
3. Do not put back and charge the battery that is already full,
for it will significantly reduce battery life cycle.
4. Since continuous charging will shorten the life of the battery,
it is unwise to place the transceiver or battery on the charger,
or take the charger as a placement seat for the transceiver.
5. Do not charge the battery when it is wet. In order to avoid any
danger please dry it first.

User Security Information
KT220

6. If the battery’s usage time is very short even when it has been
charged in completely correct way, it means the battery reached
the end of life and should be replaced by a new one.
Extension of Battery life
1. The performance of the battery will be reduced when the
temperature drops below 0ć.In cold weather, it is advised to
spare another battery for emergency. Please do not dispose the
cold batteries that can not work at low temperature but may be
usable at room temperature.
2. It may affect the normal use or charge of the battery, if it is
covered with dust. Please clean the battery with dry cloth before
loading or charging it.
Knowledge about Battery Storage
1. Please do charge it fully before putting it aside so as to prevent
damages caused by overdischarge, since the battery will self-
discharge.
2. Please take out the battery after storage for some time to fill it,
in order to avoid the reduction of battery capacity resulting from
overdischarge. It is proposed for lithium-ion/lithium-polymer
batteries to be filled in every 6 months of storage.
3. Please pay attention to the humidity of the battery storage
environment. Batteries are supposed to be stored in the
environment of room temperature, cool and dry air, to reduce
the self-discharge.
