Battery Information
Initial Use
New batteries are shipped uncharged from the factory. Charge a new battery for 12 hours
before initial use. The maximum battery capacity and performance is achieved after three
full charge/discharge cycles. If you notice the battery power runs low, please recharge the
battery.
Applicable Battery Packs
To reduce the risk of injury, charge only the battery specified by the manufacturer. Other
batteries may burst, causing bodily injury and damage.
5
Caution:
1. To avoid risk of personal injury, do not dispose of batteries in a fire!
2. Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as
household waste.
3. Never attempt to disassemble the battery.
4. All batteries can cause property damage and/or bodily injury such as burns if
conductive materials such as jewelry, keys, or beaded chains touch exposed
terminals. The conductive material may complete an electrical circuit (short circuit)
and become quite hot. Exercise care in handling any charged battery, particularly
when placing it inside a pocket, purse, or other container with metal objects.
Battery Tips
1. When charging your battery, keep it at a temperature among 5℃ - 40℃. Temperature
out of the limit may cause battery leakage or damage.
2. When charging a battery attached to a radio, turn the radio off to ensure a full charge.
3. Do not return fully charged batteries to the charger for an “extra boost”. This action
will significantly reduce battery life.
4. Never charge a battery that is wet. Please dry it with soft cloth prior to charge.
5. The battery will eventually wear out. When the operating time (talk-time and standby
time) is noticeably shorter than normal, it is time to buy a new battery.
To Prolong Battery Life
1. Battery performance will be greatly decreased at a temperature below 0 . A spare ℃
battery is necessary in cold weather. The cold battery unable to work in this situation
may work under room temperature, so keep it for later use.
2. The dust on the battery contact may cause the battery cannot work or charge. Please
use clean dry cloth to wipe it before attaching the battery to the radio.
Battery Storage
1. Fully charge a battery before you store it for a long time, to avoid battery damage due
to over-discharge.
6
2. Recharge a battery after several months’ storage (Ni-MH batteries: 3 months), to
avoid reducing battery capacity due to over-discharge.
3. When storing your battery, keep it in a cool, dry place under room temperature.
Charging the Battery
Use only the charger specified by the manufacturer. The charger’s LED indicates the
charging progress. Description for LED indicators of the two chargers (rapid-rate charger
and slow–rate charger) is shown below:

6. Charged for about 8 to 10 hours, the radio with the battery attached or the battery
alone can be removed from the charger.（available to slow-rate charger only）
Troubleshooting (MCU rapid-rate charger):
When troubleshooting, always observe the color of the LED.
No LED Indication?
1. Make sure that the power cord is plugged into an appropriate AC outlet.
Red LED flashes rapidly (0.2s on/0.2s off)?
1. Remove the battery from the charger, and:
a) Make sure that it is a HYT authorized battery. Other batteries may not charge.
b) Remove power from the battery charger, and clean the gold metal, charging
contacts of the battery and charger, using a clean dry cloth.
2. The battery temperature may be above 45℃.
3. Defective battery. Please replace it with a new one.
4. Power up the charger and place the battery back into the charger pocket. If the LED
indicator continues to flash red, replace the battery.
Note:
When the battery charger detects the proper battery conditions, rapid charging begins
automatically (steady red LED).
If the battery temperature is above 45℃, the charger will report the fault by flashing
red LED rapidly (0.2s on/0.2s off), and will not charge until the battery temperature is
below 45℃, with red LED solidly glows (Ni-MH battery only).
