1. SAFETY
SAFETY PRECAUTIONS FOR WORKING IN THE VICINITY OF A BATTERY
1) Batteries generate explosive gases during normal operation. Use in well-ventilated area.
2) Consider having someone close enough or within the range of your voice to come to your aid when you
work near a battery.
3) Do NOT smoke, strike a match, or cause a spark in vicinity of battery or engine. Avoid explosive gas,
flames and sparks.
4) Remove all personal jewelry, such as rings, bracelets, necklaces, and watches while working with a
vehicle battery. These items may produce a short-circuit that could cause severe burns.
5) Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark or short-circuit
a battery or other electrical hardware which may cause an explosion or fire.
6) Wear complete eye protection, hand and clothing protection. Avoid touching eyes while working near a
battery.
7) Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
8) Clean battery terminals before connected with the charger. Be careful to keep corrosion from coming in
contact with eyes.
9) When it is necessary to remove a battery from vehicle to charge, always remove grounded terminal from
battery first. Make sure all accessories in the vehicle are off in order to prevent an arc.
10) It is NOT intended to supply power to an extra-low-voltage electrical system or to charge dry-cell
batteries. Charging dry-cell batteries may burst and cause injury to persons and property.
11) NEVER charge a frozen, damaged, leaking or non-rechargeable battery.
12) If battery electrolyte contacts skin or clothing, wash immediately with soap and water. If electrolyte
enters eye, immediately flood eye with running clean cold water for at least 15 minutes and get medical
attention immediately.
SAFETY PRECAUTIONS FOR USING THE CHARGER
1) Do NOT place the charger in the engine compartment or near moving parts or near the battery; place as
far away from them as DC cable permits. NEVER place a charger directly above a battery being charged;
gases or fluids from battery will corrode and damage charger.
2) Do NOT cover the charger while charging.
3) Do NOT expose to rain or wet conditions.
4) Connect and disconnect DC output only after setting AC cord from electric outlet.
5) Use of an attachment not recommended or sold by the manufacturer may result in a risk of fire, electric
shock or injury to persons.
6) Do not overcharge batteries by selecting the wrong charge mode.

HYUNDAI 03
7) To reduce the risk of damage to electric plug and cord, pull by the plug rather than the cord when
disconnecting charger.
8) To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning.
9) Operate with caution if the charger has received direct hit of force or been dropped. Have it checked and
repaired if damaged.
10) Any repair must be carried out by the manufacturer or an authorized repair agent in order to avoid danger.
2. CONNECTING TO THE BATTERY
1) Identify polarity of battery posts. The positive battery terminal is typically marked by these letters or
symbol (POS,P,+). The negative battery terminal is typically marked by these letters or symbol (NEG,N,-).
2) Do not make any connections to the carburetor, fuel lines, or thin metal parts.
3) Identify if you have a negative or positive grounded vehicle. This can be done by identifying which
battery post (NEG or POS) is connected to the chassis.
4) For a negative grounded vehicle (most common): connect the RED POSITIVE battery clamp first to
the positive battery terminal, then connect the BLACK NEGATIVE battery clamp to the vehicle chassis or
negative battery terminal.
5) For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIVE battery clamp first to
the negative battery terminal, then connect the RED POSITIVE battery clamp to the vehicle chassis or
positive battery terminal.
6) When disconnecting, disconnect in the reverse sequence, removing the negative first (or positive first for
positive ground systems).
NOTICE: If battery clamps are reversely connected to battery terminals, the ERROR light will be on.
Exchange the battery clamps to solve this problem.

HYBC-2006
Using 12V BOOST
BOOST Mode is the advanced mode that require your full attention before selecting. To operate BOOST,
the charger must be connected to a 12V lead-acid battery with the battery clamps connected. For optimal
results, allow boost to complete its 5-minute charge. After 300-second boost, digital tube will show “000”,
and your are ready to start your vehicle (whether FULL LED is illuminated or not). After each boost, the
charger has mandatory 5-minute rest for safety reason (even you press the boost button again, the
charger will not work). If unsuccessful when starting your vehicle, let the battery rest for 15 minutes and try
boost again. Most vehicles will start with one (1) boost. Do not use boost more than two (2) times within
a 24-hour period. If two (2) boosts cannot successfully start your vehicle, have your battery replaced or
evaluated by a local battery store.

5. CHARGING STEPS
STEP 1: DIAGNOSIS (Check if battery has connected with the charger and also check battery voltage)
STEP 2: DESULPHATION (If battery voltage is too low, programs automatically generate pulsing current to
remove sulphate, up to 5 hours)
STEP 3: ANALYSE (Check if the battery voltage reaches to the threshold after desulphation, and charging
begins if the battery voltage is OK)
STEP 4: SOFT START (Charge with echelon constant current)
STEP 5: BULK (Charge with constant maximum current until battery voltage is reached to the threshold)
STEP 6: ABSORPTION (Provide gradually declining current charge for maximum battery voltage)
STEP 7: ANALYSE (Test if the battery can hold charge)
STEP 8: MAINTENANCE (Continuously monitor the battery, and charging current will intelligently adapt to
the variable battery voltage)
NOTICE: After full charging cycle, use this battery to start matched vehicle’s engine. If engine cannot be
activated (exclude the problem of vehicle itself), it indicates this batter has declined storage
capacity and need to be replaced.
