Operating instructions.
CAUTION: Lead-Acid batteries can emit explosive gases when charged. Prevent sparks and
fire sources close to the battery. Provide good ventilation – appliance should be used only
in well ventilated areas.
Typical charge:
1. Connect the charger connectors to corresponding battery terminals. It is recommended to
connect the positive connector before connecting the negative. Preserve correct polarity (+/-).
If the battery is installed inside a vehicle disconnecting negative (chassis/ground) clamp from
the battery is advised.
2. Ensure that the charger connectors have been connected properly and securely. Connect
the charger to AC mains power source.
The charger will automatically detect the type / voltage of the connected battery. Charging
process will start automatically - the red status LED will light up.
3. Charging process is completed when the status LED turns green. The charger will maintain
full charge state for 12V batteries and in case of a voltage drop (below 13V for 12V battery) the
charging process will be automatically restarted.
4. When the charging process is finished disconnect the charger from AC mains power source,
next disconnect negative connector from the battery. Next, disconnect the positive connector.
Charge phases description:
1. Charging the battery.
The charger uses pulse-charging method. It uses a safe 1A maximum charging current.
2. End of charge, maintenance charge.
When the battery voltage reaches cut-off value of 14V for 12V battery or 7V for 6V battery the
charge process is terminated.
The voltage is continuously monitored. When the self-discharge occurs, the charge is
reapplied automatically to maintain full charge state.
Notice:
1. In case of a AC power source break / reconnection, the charger will automatically recover
and start recharging if necessary.
2. In case of a bad battery connection, faulty battery or other error / malfunction the charger
stops operating – the green status LED will light up.
3. Charger is microprocessor controlled and is equipped with an overcharge and overload
protection.
4. Regular supervision of charging process is advised.
Safety instructions:
1. Read the instructions before using this charger.
2. This charger is intended for use only with 6V/12V batteries - VRLA, AGM, VLA, SLA, WET,
GEL, LEAD ACID. Always check battery's manual for technical specification, charger
recommendation and safety precautions. Attempting to charge other types of batteries may
