Charging Mode Explanation

NEXPEAK NC202 battery charger has four(4) modes: CAR, AGM/LiFePO4, MOTO and REPAIR. Pressed the “ ” button to switch the charging mode.
These modes are advanced charging modes that require your full attention before selecting. It is important to understand the differences and purposes of each mode. Always check with the battery manufacturer to confirm the right charging mode for your specific battery. Do not operate the charger until you confirm the appropriate mode for your battery. Below is a brief introduction:

Screen Definition

Trickle Charging Function

• Trickle/float charge function is specially designed to keep charging and maintain batteries for a long time, perfect for idle car or boat batteries, etc.
• NC202 battery charger will auto-enter trickle charging mode after fully charged also auto-detect the battery voltage, and re-start the charging process if the voltage drops below 12.5 volts.

Maintain/Repair

NOTE: Not all batteries can be repaired to 100%, you can purchase a battery tester to know it’s health status.

1. Connect the battery with AC plug and switch to repair mode, the screen displays “PUL”.
2. Usually car batteries requires about 4 hours under repair mode, and 2 hours for the motorcycle batteries and wet batteries. (You could keep the battery in repair mode if the battery is not overheated until the proper Status of Health index is reached).
3. It has current input into the battery during the repair mode and will charge the battery after a long time repair process.
4. If you need to stop the repair process in advance, just remove the charger’s clips and disconnect the power.

CAUTION: STOP repair mode immediately If the battery has serious heating or burning smell! (The main reason is due to the battery internal was vulcanized and lack of water, please replace battery asap）

TEMP Compensation

1. Winter ( ): 0-10℃
   Summer ( ): >28℃
   Normal Temperature: 10-27℃ (no icon displayed)

2. During the charging process, the charger will automatically detect the environment and working temperature, automatically adjust the best charging status to protect the battery life and ensure safe charging.

3. Detect the temperature and adjust every 3-5 seconds, there will be a very slight deviation but won’t affect the entire charging process.

8-Stage Charging

NC202 smart battery charger features eight-stage charging during the entire process as below:

• Stage-1: Battery desulphation
• Stage-2: Soft start charging
• Stage-3: Bulk charging
• Stage-4: Absorption charging
• Stage-5: Battery test
• Stage-6: Recondition charging
• Stage-7: Float & maintenance charging
• Stage-8: Monitoring stage

Troubleshooting

1. The screen does not display when the charger is connected to the battery?
   Reason: The positive and negative clips 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 also low voltage can lead to this situation, the battery will become hot while charging.
   Solution: Stop charging. Check whether the battery liquid was leaked if it’s a wet battery.

5. Can’t automatically sense it’s on a 24v battery, hooked up to 24v batteries, but stays in 12v mode, says full.
   Reason: 24v battery contains two of 12v batteries, its real voltage could be 8-10v for long time power loss, so the battery charger will charge it on 12V battery mode and in this way can’t charge the 24V batteries successfully.
   Solution: Charge two of the 12V battery separately and it will turn to 24V mode after charging to a certain voltage then charge 24V batteries.

6. Tried charging a battery overnight for over 8 hours and no charge at all, kept blinking the battery percentage icon all night long.
   Reason: battery charger can not charge totally dead batteries(0V or bad cells contained).
   Solution: try repair function or replace this battery directly.
