CAUTION.

1. To reduce risk of injury, charge lead-acid wet cells, gel, or AGM automotive-type rechargeable batteries. Other types of batteries may burst causing personal injury and property damage.
2. Do not expose the charger to rain or snow.
3. Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock, or injury to persons.
4. To reduce the risk of damage to the electric plug and cord, pull by the plug rather than the cord when disconnecting the charger.
5. Make sure the cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.
6. An extension cord should not be used unless absolutely necessary. The use of improper extension cords could result in a risk of fire and electric shock. If an extension cord must be used, make sure: a. The pins on the plug of the extension cord are the same number, size, and shape as those of the plug on the charger; b. That extension cord is properly wired and in good electrical condition;
7. Do not operate the charger with a damaged cord or plug, replace the cord or plug immediately.
8. Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged in any way; take it to a qualified serviceman
9. Do not disassemble the charger; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or fire.
10. To reduce the risk of electric shock, unplug the charger form the outlet before attempting any maintenance or cleaning. Turning off controls will not reduce this risk.
11. WARNING – RISK OF EXPLOSIVE GASES
12.  WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE TO READ THIS MANUAL AND FOLLOW THE INSTRUCTIONS EXACTLY EACH TIME BEFORE USING CHARGER.
13. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in the vicinity of the battery. Review cautionary markings on these products and on the engine.
14. Prohibit 12V STD, 12V AGM/C, 12V M, 12V LFP, RECOND, SUPPLY, and other charging modes to charge 6V lead-acid batteries or any lithium batteries;
15. 12V LFP mode is only suitable for 12V lithium iron phosphate batteries, not for other lithium batteries, it is forbidden to charge other lithium batteries;
16. For lead-acid batteries with a battery voltage of less than 3V for a long time, it is recommended to replace the battery if the voltage cannot be increased using this charger;
17. For the battery that displays BAD on the screen, it is recommended to replace the battery;
18. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

PERSONAL SAFETY PRECAUTIONS

1. Someone should be within range of your voice or close enough to come to your aid when you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching your eyes while working near the battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters the eye, immediately flood the eye with running cold water for at least 10 minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might spark or short circuit battery or other electrical part that may cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. 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.
8. Use the charger for charging Lead-acid, Gel, Calcium, AGM, and EFB batteries. It is not intended to supply power to a low-voltage electrical system other than in a starter motor application. Do not use a battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and property damage.
9. NEVER charge a frozen battery

OPERATING INSTRUCTIONS

INTENDED USE

The product is designed to charge and maintain 6V/12V lead-acid batteries with a capacity of 4 – 200 Ah. (4A:4-120Ah; 6A:4-150A; 10A:4-200Ah) The charger has been optimized to maintain the battery of your motorcycle or car when it is not being used over longer periods of time, for example over the winter. The charger is designed to charge Lithium, Gel, AGM, and standard lead-acid batteries. Any use other than that described above will damage this product and involves the risk of short circuits, fire, electric shock, etc.

PREPARING TO CHARGE

1. If necessary to remove the battery from the vehicle to charge, always remove the grounded terminal from the battery first. Make sure all accessories in the vehicle are off,so as not to cause an arc.
2. Be sure the area around battery is well-ventilated while the battery is being charged.
3. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
4. Add distilled water in each cell until battery acid reaches the level specified by the battery manufacturer not overfill. For a battery without removable cell caps, such as valve-regulated lead acid batteries, carefully follow the manufacturer’s recharging instructions.
5. Study all battery manufacturers’ specific precautions while charging and recommended rates of charge.
6. Determine voltage of the battery by referring to the vehicle’s manual and make sure the output volt-age mode is correct.

CONNECTION

To avoid sparks that could cause an explosion, the mains supply should always be disconnected before making or breaking battery connections. Connect the battery clips or ring terminals to the battery in the following order:

1. Connect the positive charging lead (RED) to the positive post of the battery (marked + / +ve or P).
2. For vehicles with the battery still installed: Connect the negative charging lead (BLACK) to the vehicle chassis (marked – / -ve or N), well away from the battery, fuel line, and hot or moving parts. For batteries removed from the vehicle: Connect the negative charging lead (BLACK) to the negative post of the battery (marked – / -ve or N). After connecting the clips, rotate them slightly so as to remove any dirt or oxidization, thus ensuring good contact.

CHARGING

1. First, make sure your battery is a 6V or 12V battery. Do not charge batteries with different operating voltages!
2. Connect the battery charger to the power supply.
3. Select the appropriate charging mode for your batteries with the “Mode” button. Refer to 2-1 Product Overview for a description of the individual operating modes.
4. Then connect the battery charger to the battery with the correct polarity. If connected with reverse polarity or short-circuit at the clamps “Err” will be lit.
5. This battery charger is equipped with an automatic memory function, i.e. whenever the AC supply is connected, it starts in the last selected mode.
6. After the charging process, disconnect the battery charger from the main supply. First, remove the clamp from the negative terminal and then from the positive terminal.

SAFETY FEATURES

This battery charger is fitted with the following safety features：

• Short circuit Protection
• Overload Protection
• Reverse Polarity Protection
• Overcharging Protection
• Over-temperature Protection

There is no reverse polarity protection in the supply mode

CHARGING TIME

A partially charged battery will take less time to charge than a fully discharged battery. The approximate charging time for a battery can be calculated using the following equation:

ADAPTER FOR SUPPLY FUNCTION USE (ONLY 10A)

1. Long press the Key for about 3-5S to Select the charger into supply mode
2. Use the below adapter to connect the charger and the appliances that need to power up.
3. Then the Appliance can be opened for use.
