Selmar Turbo 4 is a robust, 4-amp battery charger designed for 12V lead-acid batteries. It features a double-insulated, flame-retardant case and safety protections against short circuits, reverse polarity, and thermal overload. Tayna Batteries Key Features 4-Amp Charging:

Provides efficient, moderate-speed charging for standard car and leisure batteries. Moving Arm Ammeter: Allows you to monitor the charging current in real-time. Safety Protection:

Includes double fuse safety and thermal overload protection to prevent damage from overheating. Tayna Batteries Operating Instructions

To ensure safe and effective charging, follow these standard steps for lead-acid battery chargers: Preparation

Ensure the charging area is well-ventilated and away from open flames.

Check that the battery terminals are clean and free of corrosion. Connection (Charger OFF) Red Clamp: Attach to the Positive (+) terminal of the battery. Black Clamp: Attach to the Negative (-) terminal or a suitable chassis ground point. Powering Up

Plug the charger into a standard AC wall outlet only after the clamps are securely attached. Monitoring the Ammeter

The needle on the ammeter will move to show the initial charging current (up to 4 amps).

As the battery reaches full capacity, the needle will slowly drop toward zero. Disconnecting

Once the ammeter reads near zero (typically 0–2 amps), the battery is charged. Unplug the charger from the AC outlet first before removing the clamps to prevent sparks. Important Safety Precautions

Selmar Turbo 4 is a robust, manual battery charger designed for standard 12V lead-acid batteries. It is characterized by its signature "Turbo" orange flame-retardant casing and a clear moving-arm ammeter to track charging progress. Quick Setup Instructions Preparation

: Ensure the area is well-ventilated. If the battery is not maintenance-free, check that the electrolyte levels are correct. Connection Attach the Red (+) clamp to the positive battery terminal first. Attach the Black (-) clamp to the negative terminal. : Plug the charger into a standard wall outlet. Monitoring : Watch the moving arm ammeter. Needle to the Right : High current flow, battery is depleted and charging. Needle to the Left (near 1–2A)

: Current has dropped, indicating the battery is nearly full. Disconnecting

Short circuit, reverse polarity, and thermal overload protection Construction Double-insulated with a flame-retardant case Performance Analysis: : Standard automotive batteries between 16Ah and 80Ah.

: Highly durable design from a reputable British brand (Selmar); provides visual feedback via the ammeter which is often more reliable than simple LEDs for diagnostic purposes.

: Being a manual charger, it requires monitoring. Unlike "Smart" chargers, it may not automatically shut off entirely, so leaving it on for days can lead to overcharging. Tayna Batteries Troubleshooting Tips Needle doesn't move

: Check the double fuse protection. If the clamps were accidentally reversed, the internal fuse may have blown to protect the unit. Needle stays high (Right side)

: If the needle doesn't move left after several hours, the battery may have a shorted cell and cannot hold a full charge.

: While this unit has protection, always connect clamps before plugging into the wall to minimize any risk of sparks near battery gases. Tayna Batteries Mar 14, 2562 BE —

9. Frequently Asked Questions (FAQ)

Q: Can I leave the Selmar Turbo-4 connected all winter? A: Yes. In float/maintenance mode, it safely trickle charges. However, check the water level every 2 months for wet-cell batteries.

Q: How long does it take to charge a dead car battery? A: A 50Ah battery at 4A takes approximately 12-14 hours, but the smart charger may take longer due to desulfation.

Q: Does it work on lithium (LiFePO4) batteries? A: No. Standard Selmar Turbo-4 models are not calibrated for lithium. Using it will damage the battery. Look for a specific LiFePO4 mode.

Q: Why is my charger clicking? A: That is the relay engaging and disengaging during testing. If it clicks more than 5 times per minute, check for a short in the battery.

5. How to Use the “Repair” or “Boost” Mode (Important)

Many users miss this critical part of the Selmar-Turbo-4-battery-charger-instructions. The Repair/Boost mode is not for daily use.

When to use:

• Battery voltage is below 10.5V (sulfated).
• Battery has been sitting unused for months.

How to use:

1. Connect the charger normally.
2. Press and hold the "Mode" button for 5 seconds (or until the Boost icon appears).
3. The charger will pulse high voltage for 1-4 hours.
4. Monitor the battery temperature. If it becomes hot to the touch (>50°C), stop immediately.
5. After repair mode, the charger automatically switches to normal charging.

Caution: Do not use Boost mode on small batteries (motorcycle, lawnmower) unless specified. Check your battery’s max amperage.

Step 6: Disconnecting the Charger

• NEVER disconnect while charging. Wait until the "Full" or "Maintenance" light is solid.
• Unplug the charger from the AC outlet first.

1. Power Off – Make sure the charger is unplugged before connecting batteries.
2. Connect Batteries – Attach the red clamp to the positive (+) terminal and black to negative (–). For multi-bank units, connect each battery to its respective bank.
3. Set Voltage (if applicable) – Select 12V or 24V depending on your battery type.
4. Choose Mode – Use the selector switch for:
   • Standard (Lead-acid/AGM)
   • Deep Cycle/Marine
   • Lithium (if supported by your model)
5. Plug In – Connect to a mains outlet. The indicator lights should show power and connection status.
6. Monitor – Most Selmar Turbo 4 units use LED lights to show charging (red), full (green), or fault (flashing).
7. Disconnect – Unplug the charger first, then remove the clamps from the batteries.

Safety First

• Wear eye protection and gloves.
• Work in a well-ventilated area; charging can produce hydrogen gas.
• Do not smoke or have open flames near batteries.
