USER’S MANUAL
MAIN FEATURES: Smart Charge plus Maintenance and Rejuvenation
• Easy to operate and requires no technical experience
• Fully microprocessor controlled
• Battery condition check
• Enhanced battery rejuvenation (patented technology)
• Battery voltage retention analysis
• Peak pulses for long-term maintenance
• Ultra lower power consumption (ECO Mode)
• Multi Stage:
- Qualification - Battery condition check
- Battery rejuvenation
- Soft Start charging
- Bulk charging
- Absorption charging
- Voltage analysis
- Float Mode
- Long-term maintenance pulse charge
• Automatic diagnosis and charge:
On power up, the charger will automatically diagnose the battery condition,
and then determine if the rejuvenation stage or charge cycle is required.
• Patented battery rejuvenation technology:
The charger has a unique and patented rejuvenation feature which uses high
voltage equalizing and peak pulse reconditioning to repair the sulphated batteries. This feature is fully automatic and depends
on the internal impedance of the battery.
• Automatic Maintenance:
The battery charger can be left unattended; when the battery is fully charged, the charger is
programmed to automatically switch modes to maintain the battery. It will monitor the battery voltage and maintain it at peak
performance with a special pulse charge during long-term maintenance.
• Short-circuit or reverse-polarity protection:
In the event of a short circuit or reverse polarity, the charger will automatically
turn off to prevent damage.
• Will never overcharge your battery.
• Heavy-duty cables: Double insulating AC and DC cables are provided.
• Corrosion-resistant output connectors
• Output clips and ring terminals provided:
The charger comes with a quick connect fly lead and 2 different kinds of connectors,
crocodile clips, and ring terminals. The ring terminals are perfect for permanent connection to your battery. They are secured
to the battery clamps. You can take off the ring terminal from the clips, and then secure the ring terminal to the battery poles.
TEMPERATURE & SAFETY PROTECTION
The charger contains the following safety protections:
• INTERNAL OVERHEAT PROTECTION:
The battery charger has a built-in overheat and overload electronic circuit.
If overheated, the charger will decrease the charging current. If temperature is decreased, the charger will resume normal
charging. If the battery charger temperature exceeds 55 °C, it will stop charging.
• TIMER PROTECTION:
The charger provides the maximum charge time for each charging stage. The stage may time out
if you attempt to charge any severely discharged or heavily sulphated battery. Once the stage times out, the charger will stop
charging to protect your battery and the RED LED will FLASH quickly. If this situation occurs, please check the condition
of your battery.
• REVERSE POLARITY AND SHORT CIRCUIT PROTECTION:
The charger has reverse battery and short circuit protection.
If a reverse battery or short circuit occurs (red LED ON, while output leads are connected backwards or shorted), simply unplug
the charger from AC power and make the correct connections as described in this manual. The charger has firm hardware
and a smart program to automatically detect the output connections. If the charger detects a short circuit or reverse polarity,
it will not deliver any output current.
ECO MODE FOR ENERGY SAVING
This battery charger has a built-in ultra-low power consumption circuit and operates with high energy efficiency.
The charger will automatically go into ECO mode when disconnected from a battery. During ECO mode, the power drawn is less
than 1.0W, equal to energy consumption of 0.01kWh per day. Once the battery is fully charged and during long term maintenance,
the total energy consumption is around 0.1kWh per day.
