2. Safety Instructions
Always read and understand all safety instructions before operating the charger. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Ensure the charger is used in a well-ventilated area.
- Do not expose the charger to rain or wet conditions.
- Disconnect the charger from the power supply before making or breaking connections to the battery.
- Avoid short-circuiting the charging cables.
- Wear eye protection and gloves when working with batteries.
- Keep out of reach of children.
- Do not charge frozen batteries.
- This charger is protected against reverse polarity, short circuits, and overloads. However, always ensure correct connection.
3. Setup and Connection
Before connecting the charger, ensure the vehicle's ignition is off and all electrical consumers are switched off. Identify the positive (+) and negative (-) terminals on your battery.

3.1 Connecting to the Battery
- Connect the red (+) charging clamp to the positive (+) terminal of the battery.
- Connect the black (-) charging clamp to the negative (-) terminal of the battery. For vehicles, it is often recommended to connect the negative clamp to the vehicle chassis away from the battery and fuel line.
- Alternatively, use the included connection cable for fixed mounting on the battery. Connect the cable lugs to the battery terminals and then plug the charger into this fixed connection.
3.2 Connecting to Power Supply
- Once the charger is securely connected to the battery, plug the charger's power cord into a standard 220-240 V ~ 50-60 Hz electrical outlet.
- The charger will power on, and the LCD display will illuminate.
4. Operating Instructions
The Ultimate Speed ULGD A1 features intelligent microprocessor control for fully automatic charging.
4.1 Selecting a Charging Program
- The charger offers 8 selectable charging programs to optimize charging for different battery types and conditions.
- Use the "MODE" button on the charger to cycle through the available programs. The LCD display will show the selected program, voltage value, and charge status.
- The charger automatically detects whether a 12V or 24V battery is connected.
- Standard Charging: For typical charging of 12V or 24V batteries.
- Pulse Charge: This program is designed for revitalizing deeply discharged batteries. It can be used for 12V batteries with an existing voltage of > 2V.
- Winter Charging Mode: Activates for low ambient temperatures (for both 12V and 24V batteries) to ensure efficient charging in cold conditions.
- Power Supply Programs: Two dedicated programs are available to provide power during battery changes, preventing loss of vehicle settings.
4.2 Charging Process
Once a program is selected, the charger will automatically begin the charging process. The LCD display will provide real-time information on the charging progress.
The charger is designed for long-term connection, providing optimal charge maintenance without sulfate formation, which extends battery life.
4.3 Disconnecting the Charger
- Unplug the charger from the electrical outlet first.
- Disconnect the black (-) charging clamp from the negative (-) battery terminal or vehicle chassis.
- Disconnect the red (+) charging clamp from the positive (+) battery terminal.
- If using the fixed mounting cable, simply unplug the charger from the fixed connection.
5. Maintenance and Storage
Proper maintenance ensures the longevity and optimal performance of your battery charger.
- Cleaning: Disconnect the charger from all power sources and batteries before cleaning. Wipe the exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the charger in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure cables are neatly coiled and not kinked.
- Inspection: Periodically inspect the charging cables and clamps for any signs of damage, wear, or corrosion. Do not use the charger if any part is damaged.
6. Troubleshooting
If you encounter issues with your Ultimate Speed ULGD A1 charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not turn on. | No power from outlet; loose connection; internal fault. | Check power outlet with another device. Ensure power cord is fully plugged in. Verify battery connections. |
| Charger not charging. | Incorrect program selected; battery too deeply discharged (below 2V for 12V); reverse polarity; short circuit; overload. | Select appropriate charging program. For very low voltage batteries, ensure it's above 2V for 12V batteries. Check for correct polarity. Inspect cables for short circuits. Allow charger to cool if overloaded. |
| LCD display shows error. | Specific error condition (e.g., reverse polarity, short circuit). | Refer to the charger's display for specific error codes or indicators. Disconnect and reconnect ensuring correct procedure. The charger has built-in protection against reverse polarity, short circuits, and overloads. |
| Charger gets warm during operation. | Normal operation; high charging current. | This is normal. Ensure adequate ventilation around the charger. If it becomes excessively hot, disconnect and allow to cool. |
If the problem persists after attempting these solutions, please contact customer support.
