How To Use

Charging Modes Selections
NEXPEAK battery charger has six (6) modes: STD, AGM/GEL, WET, MOTORCYCLE and REPAIR. Pressed the “MODE SELECTION” button to switch the charging mode.
NOTE: the MODE button will auto-locked after 25s if there is no operation during the charging process, just unplug the clips or AC plug then reconnect it will work again.
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 description:

charging current, usually named “salt water battery” used in heavy-duty trucks/ construction machines, different from maintenance-free batteriees.
| Suitable for all kinds of motorcycles and small capacity(>2AH) lead-acid batteries.
| For battery maintenance, increase the battery health status or activate the battery. OV or bad cells batteries are forbidden to use.

Connecting to the Battery

Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery.

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. Connect the battery charger into a suitable electrical outlet. Do not face the battery when making this connection.
4. After the positive and negative clips are connected, the LCD screen will light up, battery charger starts to auto-detect the temperature, 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).
5. After the AC plug is connected, the screen will display “ ” which means entered the desulfurization process and will automatically switch to charging mode within 5 minutes. The screen will keep displaying battery voltage, current and working temperature during charging.
6. If the screen is flashing “reverse connection ” and display El-I also keep beeping sounds, then the clips should connect incorrectly or abnormally.
7. Select the suitable charging mode accordingly.
8. The screen will show FUL after the charging is ended, we suggest you to keep charging for 2 hours until the screen displays OFF for better battery performance.
9. When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).

Intelligent Memory

The battery charger has a memory function that remains the last charging mode after the new start.

Screen Definition

TEMP Compensation

1. Winter ( ):0-10°C Summer ( ): >28°C
   Normal Temperature: 10°-27°C (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.

Maintain/Repair

1. Connect the battery with AC plug and switch to repair mode, the screen displays “PUL” and ( ) flashes.
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)

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:
( Note: The wet battery/start-stop mode is on stage-6)

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

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(OV or bad cells contained).
   Solution: try repair function or replace this battery directly.
