5. Operating Instructions
Once connected and powered on, the charger will display real-time battery information. Follow these steps to begin charging:
- Select Charging Mode: Press the "MODE" button repeatedly to cycle through the available charging modes: CAR, LiFePO4, AGM, MOTO, and REPAIR. Select the mode appropriate for your battery type.
- Monitor Charging: The display will show "CHG" during active charging. You can monitor the voltage, current, and charging percentage.
- Charging Completion: When the battery is fully charged, the display will show "FUL". The charger will automatically switch to maintenance mode (trickle charge) to prevent overcharging, except for AGM batteries which do not use floating charge.
- Disconnecting: Once charging is complete and "FUL" is displayed, first unplug the charger from the AC power outlet. Then, disconnect the negative (-) black clip, followed by the positive (+) red clip from the battery terminals.

7. Troubleshooting
If you encounter issues with your TEMOLA battery charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger display shows "OFF" or is blank. | Not connected to battery, or AC power issue. | Ensure the charger is plugged into a live AC outlet and properly connected to the battery terminals. The display shows "OFF" when plugged in but not connected to a battery. |
| Charger display shows "ERR". | Reverse polarity connection. | Unplug the charger from AC power. Reconnect the red clip to the positive (+) terminal and the black clip to the negative (-) terminal. Plug AC power back in. |
| Battery not charging or charging slowly. | Incorrect mode selected, deeply discharged battery, or damaged battery. | Verify the correct charging mode is selected for your battery type. For deeply discharged batteries, the charger may take longer to initiate charging. If the battery is severely damaged, it may not accept a charge. Consult a professional. |
| Charger feels hot during operation. | Normal operation, or poor ventilation. | Some warmth is normal. Ensure the charger is in a well-ventilated area and its cooling fan is not obstructed. If it becomes excessively hot or emits smoke/odor, disconnect immediately and contact support. |
