PRODUCT FEATURES:

This appliance has been designed for charging a variety of SLA batteries (sealed lead acid batteries), as mainly used in cars, motorbikes and several other vehicles. They may be of types e.g. WET (with liquid electrolyte), GEL (with mit gel-type electrolyte) or AGM (absorbed glass mat) batteries. A special design of the appliance (also named “eight-phase-charging strategy“) enables the recharging of the battery to almost 100 % of its original capacity. Connecting the battery for a long period to the battery charger is also a good way of ensuring that your battery is kept in optimum condition. The “eight-phase-charging strategy” as follows:

Step 1: Check
Checks the battery voltage to make sure battery connections are good and the battery is in a stable condition before beginning the charge process.

Step 2: Recovery
Initializes the Recovery process, if needed, for deeply discharged or sulfated (desulfation) batteries by pulsing small amounts of current.

Step 3: Soft Start
Slow charge and protect for deeply discharged or sulfated (desulfation) batteries by multi -phase of current.

Step 4-5: Bulk
The Bulk charging process continues using both a High Rate and Medium Rate charge and returns 80% of battery capacity, Indicated by the 20%, 40%, 60%, 80% and 100% LCD.

Step 5: Absorption
Brings the charge level to 80%, The battery charger will deliver small amounts of current to provide a safe, efficient charge and limit battery gassing.

Step 6: Maintenance 1
Battery is fully charged and ready to use, indicated by the 100% CHARGE LCD and the fact that the battery icon stops flashing. In this step, the battery charger will only deliver enough current to keep the battery full. If the battery tells the charger that more current is needed, the battery charger will switch to Maintenance.

Step 7: Maintenance 2
Continuously monitors the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 6.4V (6V) and 12.8V (12V), the charger will start the Maintenance cycle until voltage reaches 6.8V (6V) and 13.6V (12V) and then discontinues the charge cycle. The cycle between Trickle and Maintenance is repeated indefinitely to keep the battery at full charge, without overcharging. The battery charger can be left connected indefinitely.

OPERATION:

WARNING!
Before you carry out any work on the battery charger always pull the mains plug out of the mains socket.

WARNING!
DANGER OF ELECTRIC SHOCK! DANGER OF DAMAGE
TO PROPERTY! DANGER OF INJURY!
Ensure that you do not strike electrical cables, gas or water pipes when you are drilling into the wall. If necessary, check the wall using a suitable detector before you drill.

CONNECTION:

• Before starting the charging or discharging procedure on a permanently installed battery in a vehicle, first disconnect the minus pole connecting cable (black) of the vehicle from the minus pole of the battery. The minus pole of the battery is usually connected to the car body.
• Then disconnect the plus pole connecting cable (red) of the vehicle from the plus pole of the battery.
• First attach the “+“ quick-release clamp (red) of the battery charger to the “+“ terminal of the battery.
• Attach the “–“ quick-release clamp (black) of the battery charger to the “–“ terminal of the battery.
• Connect the mains lead of the battery charger to an electrical power outlet socket.

DISCONNECTING:

• Disconnect the appliance from the power supply.
• Detach the “–“ quick-release clamp (black) from the “–“ terminal of the battery.
• Detach the “+“ quick-release clamp (red) from the “+“ terminal of the battery.
• Reconnect the plus pole connecting cable of the vehicle to the plus pole of the battery.
• Reconnect the minus pole connecting cable of the vehicle to the minus pole of the battery.

SELECT CHARGING MODE:

You can select different charging modes for charging different batteries at different ambient temperatures. In comparison with conventional battery charging stations, this appliance has a special function for reusing an empty battery or rechargeable battery. You can recharge an empty battery / rechargeable battery. Safe charging is ensured by means of a protection function against incorrect connection and short circuiting. Due to the installed electronics, the charging station does not begin operation directly after connecting the battery, but only starts after a charging mode has been selected.

This avoids sparking, which often occurs when connecting. The battery charger is controlled by an internal MCU (Micro-Computer Unit).

MEMORY FUNCTION / RESET:

After connection to mains, the charger automatically returns to the last charge mode used. If the charger stays on “STANDBY” press the mode key.

SWITCHING BETWEEN MODES:

Press the MODE selection button the appropriate number of times. The device switches between charging modes in the following order for 12V battery:

NOTE:

AUTOMATIC DETECTION OF BATTERY:

As soon as the battery charger has been connected to the mains, the charger recognizes the battery based on the following criteria: If the battery voltage is lower than 2.0 V or higher than 14 V, the battery is not suitable or defective.

The error message appears and flashing on the display.

NOTE:
Depending on the charging condition of the battery, the charger adapts the charging currents to ensure optimum charging of the battery. Only during the main charging phase, the battery is charged with the maximum charging current. Shortly before the maximum charging capacity has been reached the charging current is reduced. This ensures a gentle and best possible charging up to the battery’s maximum capacity.

6 V Battery:
If the battery voltage is between 2.0 and 7.0 V, the battery is identified as a 6 V battery. By pressing the MODE key the 6 V charging program is started.

12 V battery:
If a battery voltage of between 7.0 V and 10.5 V is measured, this indicates a critical range as at the lower voltage end. It is not clear whether it is a fully charged 6 V battery (which could have a voltage of 7.0 V) or a deepdischarged 12 V battery, the Step 2 Recovery will start by pulsing small amounts of current. If the battery voltage does not rise to 10.5 V within 2 hours, the error message appears and flashing on the display and returning to the standby mode.

SPECIAL FUNCTIONS:

0V battery charging.
This feature is used for zero volt batteries; it uses a very small pulse current to sense the connection of the battery. This function is used in lithium batteries, as lithium battery pack has Protection Circuit Modules (PCM),the battery pack output is 0V when the PCM have actioned.

Overheating protection
If the appliance becomes too hot during charging, the power output is automatically reduced. This protects the appliance from damage.

Trickle charging
Once the battery has been fully charged, the charger automatically changes to trickle charging. Depending on the measured voltage, the charging is interrupted or the battery is maintained in a fully charged condition with low voltage currents (0.9A or 0.4A / 0.05A).

NOTE: a battery can remain permanently connected to the charger without damage or adverse effect on its performance. The trickle charge can be used to maintain a battery.
