DANGER

READ AND UNDERSTAND ALL SAFETY INFORMATION BEFORE USING THIS PRODUCT F allure to follow these safety Instructions may result In ELECTRICAL SHOCK, EXPLOSION, FIRE, which may result in a SERIOUS INJURY, DEATH, Gr PROPERTY DAMAGE.

Update Version

1. When the charger is in Trickle mode, it will monitor the voltage of battery even though the screen is showing OFF,once the voltage drop under 12 5 Volts, the charger will automatically turn back on and charge it to full and maintain the voltage as normal
2. Force 12V mode:
   If the charger accidentally recognizes the 12V battery as a 6V battery (for example, the power of 12V battery is less than 6 Volts), you can press and hold the Mode button for 5 seconds, and the charger will be forced to switch to the  12V charging mode

IMPORTANT SAFElY WARNINGS

1. Lithium batteries are prohibited to charge, for lead-acid batteries charging only like 6V and 12V agm batteries
   Do not attempt to use the product with any other types of battery Charging other battery chemistries may result in injuries, death or property damage

2. CAN NOT charge totally dead batteries (0V or bad cells contained)
   Do not charge a battery if you are unsure of the battery’s specific chemistry or voltage
   Test the battery and understand the battery health status before charging

3. This battery charger is made by waterproof materials but can not sustain in water or rainy environments

4. Contact us for replacement if you found the charger is abnormal or the plug and power clips are damaged or cracked

5. Stop charging if the battery is damaged or liquid overflow around your battery
   Stop the charging immediately if you found the battery is overheated

6. Charging the batteries in the vehicle is not allowed if you are going to use the repairing mode, which may result in damages of car electronics

HOW TO USE

1. Connect the positive (red) battery clamp to the positive (+) battery terminal

2. Connect the negative (black) battery clamp to the negative (-) battery terminal

3. After the positive and negative clips are connected, the LCD screen will light up, battery charger starts to auto-detect the voltage, current and remaining capacity (Note: After the charging ended, the battery needs to be put for an  hour and the remaining capacity of the battery will be shown in the below picture)
   

4. ­If Positive and negative terminals are Connected incorrectly Or abnormally, the screen reverse connection” icon flashes, displaying Er”

5. Select the suitable charging mode accordingly

6. After charging is ended, the screen battery power bar will display FUL, we recommended that you keep charging for about one to two hours until the screen displays OFF for better battery performance

7. When disconnecting, first disconnect the charger power, and then remove the positive and negative clips, charging is complete

CHARGING TIME REFFRENCE

Low current(1 75 Amp) charging helps to protect batteries during long-time charging process, the larger battery needs longer time to get fully charged

CHARGING MODE SELECTIONS

NEXPEAK NC175 battery charger has 3 modes: STD, REPAIR and TRICKLE
The STD mode is quick charge type that can output 1 75-amp(Max) current to fully charge the battery and restore the performance The TgCKLE mode is more suitable for long time charging and maintaining the battery which changes to lower output to protect the battery REPAIR mode helps recover the battery’s health

suitable for all 6V and 12V lead-acid batteries, auto shut-off once fully charged
suitable for long time charging and maintaining, won’ t shut off and keep charging the batteries
suitable for battery maintenance, increase or recover the battery health and activate it

TRICKLE CHARGING MODE

On the basis of standard mode charging, when the voltage of 6V battery is lower than 6 25¥ and 12V battery is lower than 12.5V, it will automatically enter into intelligent charging mode

7- STAGE CHARGING

The battery charger has seven-stage charging during the entire process: desulfurization, trickle charging, constant current charging, constant voltage charging, battery current detection, compensation charging and floating charging The  charging process is as below 

1. Desulfurization
2. Tickle charging
3. Constant current charging
4. Constant voltage charging
5. Battery current detection
6. Compensation charging
7. Floating charging

REPAIR FUNCTION

1. After long-term use of the battery, we suggest you to use the repair mode once every 1 to 6 months to keep the battery health status or activate the battery
2. Connect the battery and plug in the power, press the MODE” button three times to enter the repair mode, the screen shows putt”, (repair icon) flashing
3. Toy car battery is recommended to repair for about 2 hours, motorcycle battery is recommended to repair for about 4 hours. (f the battery does not heat up, you can extend the repair time)

SCREEN DEFINITION

TROUBLE SHOOTING

1. The screen does not display when the charger is connected to the battery
   Reason The positive and negative chips are connected incorrectly or the battery is dead
   Solution: Check whether the clips are connected reversed, use a battery tester to see whether the battery is dead or not

2. Screen will display the voltage but don’t charge the battery Reason: There is no input voltage
   Solution: Connect to a 110-220V AC socket

3. The battery can’t be charged and is low current, but the screen display
   (FUL) indicates fully charged
   Reason This is caused by the battery’s vulcanization and inside lack of water, low voltage or leave it unused for a long time The internal resistance of the battery and capacity will reduce greatly, Then it will reach full voltage quickly  while charging
   Solution: Choose repair mode to reactivate the battery!

4. Can’t fully charged after a long time
   Reason: battery vulcanization or lack of water, or battery is out of the charger’s capacity
   Solution Stop charging. Check whether the battery liquid was leaked if it’sawet battery
