IMPORTANT SAFETY INSTRUCTIONS

IMPORTANT SAFETY INSTRUCTIONS 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 wate 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.
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.

ABOUT INF-C4A

2. Built-in intelligent microprocessor makes charging faster, easier and safer.
3. This charger has safety features, including spark proof, protection for reverse polarity, short circuit, overheat and overcharge.
4. When starting, the battery voltage type is 12V by default. The user can select battery voltage type by pressing 6V/12V button in standby.
5. When the charger is powered on, it enters the standby mode by default . The user can select functions including STD, AGM, CAL, LiFePO4, REPAIR by pressing FUNCTION button.
6. When charging starts, the battery current can be selected through the “CHARGE RATE” button, onces the battery is 100% fully charged, a maintenance status will activate to maintain batteries during prolonged periods of storage.

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 clamp first to the positive battery terminal, then connect the BLACK NEGATIVE clamp to the negative battery terminal or vehicle chassis.
5. For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIVE clamp first to the negative battery terminal, then connect the RED POSITIVE clamp to the positive battery terminal or vehicle chassis.
6. When disconnecting, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).
7. A marine (boat) battery must be removed and charged on shore. To charge it on board requires equipment specially designed for marine use.

CHARGING MODES

INF-C4A has 9 modes: Standby, 12V STD , 12V AGM, 12V CAL, 12V LITHIUM (LIFEPO4), 6V STD, 6V AGM, 6VCAL,12V REPAIR. Do not operate the charger until you confirm the appropriate charge mode for your battery.

CAUTION:
If you choose 12V Mode(s) for 6V battery, the 6V battery will be damaged.

NOTICE

automatically enter the low temperature charging mode;
| If the ambient temperature is higher than 30 ºC, the charger will automatically enter the high temperature charging mode. If the charging temperature is too high, the charger will also automatically enter the high temperature charging mode;
| The charger will enter the repair mode automatically or manually;
| The charger enters the 8 step of the 8 step charging mode to keep the battery charged (MAINTENANCE)

USING 12V LITHIUM

This mode is designed for 12V lithium-ion (LiFePO4) batteries only. Some lithium ion batteries may be unstable and unsuitable for charging. Consult the lithium battery manufacturer before charging and ask for recommended charging voltage and current.

USING REPAIR (12V ONLY)

This mode is for LEAD ACID batteries only. It is an advanced battery recovery mode for repairing old, idle, stratified or sulfated batteries. NOT all batteries can be recovered. For optimal results, take the battery through a full charge cycle, bringing the battery to full charge, before using this mode. One REPAIR cycle can take up to EIGHT (8) HOURS to complete the recovery process and will enter to standby when completed. This mode uses a high charging voltage and may cause some water loss in WET cell batteries. Plus, some batteries and electronics may be sensitive to high charging voltages. To minimize risks, disconnect the battery from the vehicle before using this mode.

CHARGING STEP

• 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 sulph ate, up to 10 minutes).
• 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).
• STEP 8: MAINTENANCE (Continuously monitor the battery, and charging current will intelligently adapt to the variable battery voltage).
