 PERSONAL PRECAUTIONS  The appliance is not intended for use by young children or infirm persons without supervision; young

children should be supervised to ensure that they do not play with the appliance.

 When the battery charger is charging for automobile batteries, the following steps should be done:  The battery terminal is not connected to the chassis has to be connected first. The other connection is to

be made to the chassis, remote from the battery and fuel line. The battery charger is then to be connected to the supply mains.

 After charging, disconnect the battery charger from supply mains, and then remove the chassis connection

and the battery connection, in this order.

 For appliance with type Y attachment:  If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or similarly

qualified person in order to avoid a hazard.

 Someone should be within range of your voice or close enough to come to your aid when you work near a

lead-acid battery. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes. Wear complete eye and clothing protection. Avoid touching eyes while working near battery.

 If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,

immediately flush eye with running cold water for at least 10 minutes and get medical attention immediately.

 NEVER smoke or allow a spark or flame in vicinity of battery or engine.

 Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery

or other electrical part that may cause explosion.

 When working with a lead-acid battery, remove personal metal items such as rings, bracelets, necklaces,

watches, etc. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.

 It is not intended to supply power to a low voltage electrical system other than in a power supply

application. Do not use battery charger for recharging dry-cell or non-rechargeable batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property. While charge the impropriety type of battery will cause battery serious damage.

 NEVER charge a frozen battery.  NEVER charge the impropriety type of battery.  NEVER charge the impropriety Voltage of battery.  NEVER block off the ventilation louver of the chrger.  PREPARING TO CHARGE  If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first.

Make sure all accessories in the vehicle are off, so as not to cause an arc. Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully blown away by using a piece of

cardboard or other non-metallic material as a fan.

 Clean battery terminals. Be careful to keep corrosion from coming into contact with eyes. Add distilled

water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge excessive gas from cells. Do not overfill. For a battery without caps, carefully follow manufacturer's recharging instructions.

 Study all battery manufacturers’ specific precautions such as removing or not removing cell caps while

charging and recommended rates of charge.

 Determine voltage of battery by contacting battery manufacturer and make sure it matches output rating of

battery charger.

 CHARGER LOCATION  Locate charger as far away from battery as dc cables permit.  Never place charger directly above battery being charged; gases from battery will corrode and damage

charger.

 Never allow battery acid to drip on charger when reading gravity or filling battery.  Do not operate charger in a closed-in area or restrict ventilation in any way.  Do not set a battery on top of charger.  DC CONNECTION PRECAUTIONS  Connect and disconnect DC output terminals only after removing charger from AC outlet.  Never allow DC output terminals to touch each other.  If problems arise connecting the output leads, solicit the aid of your Dealer from whom you purchased this

product or the charger manufacturer for finding a suitable connection device for your application.

 FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR BATTERY

MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:

 Position AC and DC cords to reduce risk of damage by hood, door or moving engine part.  Stay clear of fan blades, belts, pulleys, and any other parts that can cause injury to persons.  Check polarity of battery posts POSITIVE (POS., P, +) post usually has larger diameter than NEGATIVE -

(NEG., N, -).

 Determine which post of battery is grounded (connected) to chassis.  For negative-grounded vehicle, first connect POSITIVE (RED) clip from charger to POSITIVE (POS., P, +)

ungrounded post of battery. Then connect NEGATIVE (BLACK) terminal to vehicle chassis or engine block away from battery.

 For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from charger to NEGATIVE (NEG., N, -)

ungrounded post of battery. Connect POSITIVE (RED) clip to vehicle chassis or engine block away from battery keeping the battery terminal well removed there from.

 Do not connect any charger clips to carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy

gauge metal part of the frame or engine block.

 Connect charger AC supply cord to electric outlet.  When disconnecting charger, turn switches (if supplied) to off, disconnect charger from AC power, remove

clip from vehicle chassis, and then remove clip from battery terminal. See operating instructions for length of charge information.

 FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY

MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:

 Check polarity of battery posts. POSITIVE (POS., P, +) battery post usually has a larger diameter than

NEGATIVE (NEG., N, -) post. Some batteries are equipped with 'Wing-Nut' terminals allowing for easy placement of the terminals to these posts.

 Attach at least a 24-inch long 18-gauge (AWG) insulated battery cable to NEGATIVE (NEG., N, -) battery

post.

 Connect POSITIVE (RED) charger terminal to POSITIVE (POS., P, +) post of battery.  Position yourself and free end of cable as far away from battery as possible - then connect NEGATIVE

(BLACK) terminal to free end of cable.

 Do not face battery when making final connection.  Connect charger AC supply cord to electrical outlet  When disconnecting charger, always do so in reverse sequence of connecting procedure and break first

connection while as far away from battery as practical

 A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment

specially designed for marine use.

STEP 2 - Connecting the Battery charger to your Battery

 If the Battery is out of the vehicle:

o Connect the Red lead from the charger to the positive (+) battery terminal. o Connect the Black lead from the charger to the negative (-) battery terminal.

 If Battery is still in the vehicle, determine if the vehicle is positively or negatively

earthed.

o If Negatively Earthed (Most Common) – FIRST Connect the Red (+) battery

charger lead to the positive (+) Battery post and then connect the Black (-) battery charger lead to the vehicle’s chassis and away from the fuel line.

o If Positively Earthed – FIRST Connect the Black (-) battery charger lead to the

Negative (-) battery post and then connect the Red (+) battery charger lead to the Vehicle’s chassis and far away from the fuel line.

STEP 3 - Connect the battery charger to Mains Power

 Connect the battery charger to the Mains Powered socket.  The Charger will automatically start when AC power is connected and switched on.

(Note: If the Fault Indicator LED illuminates Red, please check your connections as it’s

likely that the Positive and Negative Leads are reversed. Refer to Trouble Shooting Page for further information)

THE CHARGING PROCESS:

The charging stages and performance are as follows:

ECO Mode

If ac power is connected, and the battery is not connected, after 10 seconds, the charger will automatically go into ECO mode.

 The Green LED is fast flashing indicates the ECO mode.

Battery Initial Qualification

When the battery is connected and ac powers on, the program will automatically run qualification as the following processes:

- Detects the battery internal impedance and initial voltage.

- Determine the charging rate acceptance.

- Diagnoses the battery sulphated condition.

- Senses whether the battery is still connected into the vehicle electronic circuit. The program will determine the next stage subjected to above result of initial qualification.

 The Red LED is ON and Yellow LED is ON, (the initial voltage is at very low level).

Enhanced Battery Rejuvenation

If the initial qualification detected that the battery was in poor condition, our unique rejuvenation process (patented in USA and Europe) will begin automatically. During the rejuvenation

process, a high voltage equalizing and peak pulse reconditioning charge is used to repair the sulphated battery, this unique patented feature will break down and dissolve the lead-sulphate crystal built up on the battery plates, balance out the high concentrations of acid, which is to extend your battery life and performance.

If the battery voltage does not reach 9V within 24 hours, the Rejuvenation process will be timed out.

 The Blue LED is flashing indicates the Rejuvenation stage.

If the program detects the battery can be normally accepted charging current, it will directly go into Soft start stage; if the battery still can not accept the charging current after 24 hours rejuvenation, it expresses the Battery Rejuvenation fails and the battery is not healthy.

 The Red LED will be ON to indicate the battery rejuvenation failure.

Smart Charging Mode

There are following stages:

o Soft start Charging Mode (C.C. Mode)

 Blue Charging LED is flashing.  Gently ramps up the battery voltage to 11V, if the battery voltage doesn’t

reach 11V within 6 hours, the charger will engage a safety timer protection and RED faulty LED will start flash.

o Bulk Charging Mode (C.C. Mode)

 Blue Charging LED is ON.  The battery can be charged about 80%.  The charger delivers an almost constant current of the maximum output until

the battery voltage reaches the preset voltage value within 24 hours, if the battery voltage doesn’t reach preset voltage value within 24 hours, the charger will engage a safety timer protection and RED faulty LED will start flash.

o Absorption Mode (C.V Mode)

 Green absorption charging LED is ON.  The battery can charge up to almost 100%.  The charging current tapers and the charging voltage are kept constant at the

preset value without overcharging.

o Equalization charging

 Blue Bulk LED and Green Equalization LED both flashing.  A well proven process that carefully equalize the battery to store it’s full

capacity, the Equalization stage for Calcium battery selection is automatic. The equalization stage for AGM & WET and GEL battery only occurs if the in Initial start voltage is below 11 Volts.

o Analysis Mode ( Battery retention test Mode)

 The charging is interrupted for a short period for battery voltage measured  If the battery voltage falls too quickly, the battery is probably faulty.

 The Yellow Charging LED is ON (if above situation occurred)

o Float Mode (Safe voltage level of 13.6V)

 Full Green LED is ON.  The Float Mode allows the charger to effectively be left connected to your

batteries; it works at a safe level of 13.6V, and ready for use.

o Maintenance mode (Special pulse for long term maintenance)

 Full Green LED is ON.  The program engages a special charging waveform and monitors the battery

voltage variety, if the battery voltage sinks, the special pulses will keep the battery in optimal state, if the battery voltage drops even lower, the battery charger will switch into Bulk charging stage. The maintenance mode allows the charger can be connected to the battery over the course of a season; if possible; check the electrolyte liquid level in the battery.

STEP 4 - Disconnecting the Battery charger from Battery

 If the Battery is out of the vehicle.

o Switch OFF and Remove the AC Power Plug from the outlet.

o Remove the Black lead and then the Red lead.

o Check electrolyte levels if possible.

(As they may need topping up with distilled water after charging)

 If the Battery is in the vehicle.

o Switch OFF and Remove the AC Power Plug from the outlet.

o Remove the lead from the vehicle chassis.

o Remove the lead from the battery.

o Check electrolyte levels if possible.

(As they may need topping up with distilled water after charging)
