BATTERY CHARGING SYSTEM
The Hetronic UCH-2 is a new and improved battery
charging system. It includes upgraded features to better
charge and troubleshoot the battery.
Battery and charger contacts are gold-plated and self-
cleaning to ensure positive connection. The battery and
charger contacts are mechanically cleaned each time the
battery is removed from or inserted into the battery
compartment.
Features
•Normal charge or Fast charge of Hetronic standard
batteries
•Trickle charge - After charging process is complete,
battery can remain in charger without being damaged
by over-charge.
•Battery diagnostics - Charger determines if battery
is damaged.
•Gold plated contacts ensure clean, positive contact
between battery and charger.
•LED status lights indicate charging process as well
as battery diagnostics
The Battery Charger
One battery charger is designed for 115/230 VAC and plugs
into a typical wall outlet. Another charger is designed for
12/24 VDC and is wired into the constant crane/machine
power source.
When the battery is inserted into the charger, a flashing
“CHARGE” LED lights. The charge process is terminated
by detecting peak battery voltage or after 5 hours and the
“READY” light goes on. When the “READY” light is lit, the
charger continues to "trickle" charge the battery.
NOTE: If the battery is bad and has an open cell, no LEDs
will light up. If the battery has a shorted cell, the “CHARGE”
LED will blink continuously after ca. 10 minutes. In either
case, the battery must not be used. Properly dispose of the
bad battery.

Charging the Battery
1. Insert the battery with both guide pins in the
corresponding guide bars into the battery
compartment of the battery charger.
2. Press the battery on the marked spot until it latches
into its compartment. The LED labeled “CHARGE”
flashes for two seconds, then stays lit during the
charging process.
3. When the battery is fully charged, the “READY” LED
lights up and the “CHARGE” LED goes off. Charging
time could take up to 5 hours, depending on the
condition of the battery.
4. Leave the battery in the charger until it is needed. The
charger supplies a “trickle” charge but will not over-
charge the battery.
Fast Charge
1. Insert the battery into the charger as described
above. The LED labeled “CHARGE” flashes for two
seconds, then stays lit.
2. Press the “FAST CHARGE” button. The FAST
CHARGE LED lights also and stays lit during the
charge process.
3. When the battery is fully charged, the “READY” LED
lights up and the “CHARGE” and “FAST CHARGE”
LEDs turn off.
If you have questions or problems operating your battery
charger, please contact your dealer or Hetronic.
Hetronic Battery Information
Standard Hetronic rechargeable batteries are the nickel
metal hydride type. These batteries have no “memory
effect” when charging a battery that is not fully discharged.
Battery Technical Specifications
Changing the Battery
The battery voltage is monitored continuously by the
transmitter.
A buzzer in the transmitter sounds when the battery is
nearly discharged. When the transmitter signals, the
battery must be changed immediately.
1. Position the crane/machine into a safe place or safe
condition within 30 seconds after hearing the signal.
NOTE: If your transmitter is equipped with Advanced Low
Battery Indication, you have up to 10 minutes to place the
crane/machine in a safe position. The exact amount of time
is determined by customer specifications. Refer to the
technical drawings for each radio remote control system.
2. Press the E-stop pushbutton.
3. Switch the transmitter "OFF".
4. Push the discharged battery slightly forward and lift it
out of the battery compartment.
5. Insert a fully charged battery.
6. Follow "Start-up Procedure" to begin operation.
