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.

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.
