USER'S MANUAL
The Universal Battery Charger (UBC-
24) is designed to charge lead-acid
and lithium batteries for the LR-24,
LR-20 Series (and earlier Smith-Root
24V models) Electrofisher Systems.
The UBC-24 is a charger tailored for
maintenance-free batteries as well as other
types of lead-acid batteries.
The UBC-24 has a fully automatic, three stage
charge sequence with an electronically timed
routine and a desulfation mode.
Stage 1
- Constant Current Mode.
The charger starts with maximum current until the
battery reaches a preset voltage (red LED light).
Stage 2
- Timed Constant Voltage Mode.
The charge is electronically controlled with a
fixed voltage ceiling which prevents excess battery gas emission and over-charging (orange
LED light).
Stage 3
- Final Mode.
Battery is fully charged (green LED light).
Full electronic protection is provided against short circuit and reverse battery connection.
CHARGING
READ THESE INSTRUCTIONS BEFORE USING THE CHARGER
The battery charger is only designed for indoor use and should not come into contact
with water or dust. In order to avoid overheating, the charger should not be covered
when it is in use.
Chargers filled with molding material are splash-proof, but must not be immersed in water.
The socket should be easily accessible. If an operational error occurs, the plug should
be immediately removed from the socket. The charger contains dangerous voltages and
the cover should not be removed. All service or maintenance work should be carried out
by qualified personnel who can get assistance by contacting the manufacturer’s agent.
A fuse protects the product against short-circuiting and overloading. The charger is
designed for charging lead batteries. For safety reasons, individual battery types should
have a minimum capacity. Recommended battery capacity: 6V 4-12Ah, 12V 3-12Ah, 24V
1.5-12Ah. Contact the battery manufacturer for the specific battery. Do not attempt to
charge batteries that are not rechargeable.
SECTION 6: BATTERY CARE AND MAINTENANCE
CAUTION:
Old, sulphated batteries usually have a reduced capacity and are
difficult to charge. The charge current will fall quickly as if the battery had
received a full charge. Even though a battery in this condition should be
replaced, it will retain a small charge.
