Components clau:
- Pantalla LCD: Espectacles voltage, current, temperature, charge percentage, and mode.
- Botó de selecció de mode: Touch-sensitive button to cycle through charging modes.
- Bateria Clamps: Vermell (+) i negre (-) per connectar-los als terminals de la bateria.
- Cable d'alimentació: For connecting to AC power outlet.
- Ventilador de refrigeració: Situat al lateral per a la dissipació de la calor.
Configuració i connexió
- Prepareu la bateria: Ensure the battery terminals are clean and free of corrosion. If charging a battery in a vehicle, ensure the vehicle is turned off and in park/neutral with the parking brake engaged.
- Connecteu la bateria Clamps:
- Connecteu el VERMELL (+) cl positiuamp al terminal positiu (+) de la bateria.
- Connecteu el NEGRE (-) cl negatiuamp al terminal negatiu (-) de la bateria.
- For vehicle batteries: If connecting to a battery installed in a vehicle, connect the negative clamp to the vehicle chassis away from the battery and fuel line if the negative terminal is grounded to the chassis. Consult your vehicle's manual for specific instructions.
- Connecteu-vos a l'alimentació: Plug the charger's power cord into a standard 110-220V AC, 50-60Hz electrical outlet. The charger will automatically detect the battery voltage (12V or 24V) and begin the charging process.
- Pantalla inicial: The LCD display will illuminate, showing current battery voltage, temperature, and charging status.
Instruccions de funcionament
The charger operates automatically, but you can select specific modes for optimal charging.
Selecció del mode
Press the "MODE SELECTION" touch button to cycle through the available charging modes:
- ESTÀNDARD (ESTÀNDARD): For standard lead-acid batteries.
- AGM/GEL: For AGM (Absorbed Glass Mat) and Gel batteries.
- MÚLID: For wet cell batteries.
- MOTO: For smaller 12V motorcycle batteries, also used for trickle charging.
- REPARACIÓ: Pulse repair mode for desulfating and restoring old batteries.

7-Stage Automatic Charging Process
The charger employs a sophisticated 7-stage charging process to optimize battery performance and lifespan:
- Desulfurization: Uses pulse voltage to break down lead sulfate crystals in sulfated batteries.
- Càrrega de degoteig: Initial low current charge for deeply discharged batteries.
- Constant Current Charge: Charges the battery at a constant high current until it reaches a certain voltage.
- Vol. Constanttage Càrrec: Charges at a constant voltage, with current gradually decreasing.
- Battery Current Detection: Monitors battery current to ensure optimal charge.
- Compensation Charging: Fine-tunes the charge based on battery condition.
- Càrrega flotant: Maintains the battery at full charge with a low, constant voltage, preventing overcharge.
Temperature Compensation (Summer/Winter Mode)
The charger automatically adjusts charging parameters based on ambient temperature to prevent overcharging in hot conditions and ensure full charge in cold conditions.

Figura 4: Automatic temperature compensation. In Summer Mode (>28°C), charging voltage is reduced. In Winter Mode (0-10°C), charging voltage augmenta.
- Summer Mode (>28°C): When the temperature is high, the charger reduces the charging voltage to prevent overcharging and damage to the battery.
- Winter Mode (0-10°C): In cold weather, battery resistance increases. The charger automatically increases the charging voltage to ensure the battery receives a full charge.
Pulse Repair Function
The "REPAIR" mode utilizes pulse technology to detect and restore lost battery performance by addressing sulfation and acid stratification. This can extend battery life and improve starting power. Note: This function cannot activate or charge totally dead batteries.
Float/Trickle Charge Mode
For long-term battery maintenance, especially during winter or extended storage:
- First, fully charge the battery using the appropriate mode (STD/AGM/GEL/WET). The display will show "FUL" when complete.
- Then, switch the charger to "MOTORCYCLE" mode. The charger will automatically enter trickle charging mode, maintaining the battery's charge without overcharging.
Manteniment
- Neteja: Disconnect the charger from power and the battery before cleaning. Wipe the exterior with a soft, damp tela. No utilitzeu productes químics agresivs o abrasius.
- Emmagatzematge: Store the charger in a cool, dry place when not in use. Ensure cables are neatly coiled and not kinked.
- Inspecció del cable: Periodically inspect the power cord and battery clampComproveu si hi ha signes de danys, desgast o corrosió. No utilitzeu el carregador si alguna peça està danyada.
- Terminals de bateria: Mantingueu els terminals de la bateria nets per garantir un bon contacte elèctric.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El carregador no s'encén. | No power from outlet; loose connection; internal fault. | Check power outlet; ensure power cord is securely plugged in; contact support if problem persists. |
| "FUL" displayed but battery not fully charged. | Battery may be faulty or deeply sulfated; incorrect mode selected. | Try "REPAIR" mode; test battery with a load tester; ensure correct mode is selected for battery type. |
| Charger displays "Reverse" or error. | Connexió de polaritat inversa. | Disconnect from power, then reconnect clamps correctly (Red to +, Black to -). |
| El carregador s'escalfa durant el funcionament. | Normal operation; poor ventilation; excessive load. | Ensure adequate ventilation around the charger; this is normal for high-current charging. The charger has thermal protection. |
| Pulse repair not working. | Battery is completely dead or severely damaged. | The repair function cannot revive totally dead batteries. Battery may need replacement. |
