IMPORTANT SAFETY INSTRUCTIONS

SAFETY PRECAUTIONS FOR WORKING IN THE PROXIMITY OF A BATTERY

1. Batteries generate explosive gases during normal operation. Use in a 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 Proximity 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.
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 AQ3500

1. The AQ3500 is designed for charging all types of 12V lead-acid,6V lead-acid and 12V lithium-ion batteries, including WET (Flooded), GEL, MF (Maintenance-Free), EFB (Enhanced Flooded Battery), AGM (Absorbed Glass Mat), and LIB (Lithium Ion) batteries.
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, overcurrent, overcharge and overheat.
4. It has auto-memory, which returns to last selected mode when restarted (except Standby Mode).
5. When battery level indicator turns to 100% solid Green LED, it will automatically switches from full charge to maintenance status to maintain batteries during prolonged periods of storage without overcharging or damaging the battery.
6. The AQ3500 has four external holes for mounting. Mount the charger in a desired location with equipped self-drill screws. It is important to keep in mind the distance to the battery.

CONNECTING TO THE BATTERY

1. Identify the 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 symbols (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 /ring connector first to the positive battery terminal, then connect the BLACK NEGATIV clamp/ring connector to the negative battery terminal or vehicle chassis.
5. For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIV clamp/ring connector first to the negative battery terminal, then connect the RED POSITIVE clamp/ring connector 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. Follow these steps when using 12V accessory plug: keep the vehicle hood open. Connect the end of the 12V accessory plug to the charger; insert the 12V accessory plug into the vehicle’s 12V outlet. If the vehicle’s ignition key has to be on in order for the 12V outlet to supply/receive power, turn the key, without starting the engine.
8. A marine (boat) battery must be removed and charged on shore. Charging it on board requires equipment specially designed for marine use.

CHARGING MODES

AQ3500 has eight modes: 12V NORM, 12V COLD/AGM, 12V SMALL NORM, 12V SMALL COLD/AGM, 6V NORM, 12V LITHIUM and 12V REPAIR. Some charge modes must be held for three (3) seconds or / and pressed to enter the mode. Do not operate the charger until you confirm the appropriate charge mode for your battery.

These “Hold or/and Press” modes are advanced charging modes that require your full attention before selecting.

Using 6V NORM (Hold)
This model is designed for 6V lead-acid batteries only. Consult the battery manufacturer before using this mode.

Using 12V LITHIUM (Hold & Press)
This model is designed for 12V lithium-ion batteries only, including LiFePO4. 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 12V REPAIR (Hold & Press)
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. When this mode is chosen, do remember to press the Mode button for choosing the appropriate 12V Mode(s). One REPAIR cycle can take up to eight (8) hours to complete the recovery process and will enter to charge (8 steps charging cycle) 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 STEPS

• STEP 1: DIAGNOSIS (Check if the battery has connected with the charger and also check the battery voltage)
• STEP 2: DESULPHATION (If battery voltage is too low, programs automatically generate a pulsing current to remove sulfate, for 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 a charge)
• STEP 8: MAINTENANCE (Continuously monitor the battery, and the charging current will intelligently adapt to the variable battery voltage).

BATTERY LEVEL INDICATOR

LED COMMUNICATION OF ABNORMAL RESULTS

NOTICE:
The following situation indicates that the battery needs to be replaced, although there is no abnormal result in LED communication.

After a full charging cycle and with 100% of the battery level indicator, use this battery to start matched vehicle’s engine. If the engine cannot be activated (excluding the problem of the vehicle itself), it indicates this battery has declined storage capacity and need to be replaced or try REPAIR Mode for recovery.
