Setup
Follow these steps for proper installation and connection of your battery monitor:
- Prepare the Installation Location: Ensure there is adequate space for the monitor (refer to dimensions in Figure 5) and that the surface is clean and dry.
- Connect the Supporting Terminal Wire: Insert the provided terminal wire into the product's socket. Pay close attention to the orientation and direction of the buckle to ensure a secure fit.
- Connect to Battery:
- Connect the red wire to the positive (+) electrode of your battery.
- Connect the black wire to the negative (-) electrode of your battery.
- If your model includes a temperature sensor (optional), place it close to the surface of the battery for accurate readings.
- Power On: Once connected, the battery power percentage and voltage will be displayed on the LCD screen.

Operating Instructions
The Walfront LCD Battery Monitor is designed for straightforward operation:
- Display Modes: The LCD screen simultaneously displays the battery's percentage capacity and its current voltage.
- Switching Display (if applicable): If your model supports temperature display, press the button on the unit to switch between voltage/percentage and temperature readings.
- Sleep Mode: The product is designed to enter a sleep state after approximately 10 seconds of inactivity to conserve power.
- Waking Up: To wake the device from sleep mode, simply press any button on the unit.
- Alarm Function: This specific model includes an alarm function. Refer to the product's detailed specifications for alarm thresholds and indicators.
Maintenance
To ensure the longevity and optimal performance of your battery monitor, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the display and casing. Do not use abrasive cleaners, solvents, or immerse the device in water (unless specifically designed for such conditions, as shown in the video, but general cleaning should be dry).
- Storage: When not in use for extended periods, store the monitor in a cool, dry place, away from direct sunlight and extreme temperatures.
- Connection Check: Periodically inspect the wiring and connections for any signs of wear, corrosion, or looseness. Ensure the pluggable connector is securely seated.
Troubleshooting
If you encounter issues with your Walfront LCD Battery Monitor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device not turning on | Incorrect wiring; No power to the battery; Loose connection; Battery voltage outside range. | Check red and black wire connections to the battery. Ensure battery has charge. Verify connections are secure. Confirm battery voltage is within DC 8V-100V. |
| Inaccurate readings | Incorrect battery type setting (if adjustable); Faulty connection; Device malfunction. | Ensure the monitor is compatible with your battery type. Re-check all connections. If issues persist, contact support. |
| Display flickering or unstable | Unstable power supply; Loose connection; Electromagnetic interference. | Check the stability of the power source. Secure all connections. Relocate the device away from strong electromagnetic fields. |
| Device enters sleep mode too quickly | Normal operation (10-second inactivity timer). | This is a power-saving feature. Press any button to wake the device. |
