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. In either case,
the battery must not be used. Properly dispose of the
bad battery.
