4. Opsætning
Follow these steps to set up your Haisito C26A charger for operation:
- Klargør batteriet: Sørg for, at batteripolerne er rene og fri for korrosion. Rengør dem om nødvendigt med en stålbørste.
- Tilslut til batteri:
- Tilslut rød (+) clamp til den positive (+) pol på batteriet.
- Tilslut sort (-) clamp til den negative (-) pol på batteriet.
- Sørg for, at forbindelserne er sikre.
- Automatisk genkendelse: Opladeren vil automatisk registrere batterivolumentage (6V, 12V, or 24V) and type (Lithium, LiFePO4, Lead-Acid). This information will be displayed on the LCD.
- Tilslut til vekselstrøm: Plug the charger's AC power cord into a standard 100-240V AC wall outlet. The charger will power on and begin the charging process based on its automatic detection.

5. Betjeningsvejledning
5.1 9-Stage Smart opladningsproces
The Haisito C26A utilizes a 9-stage charging process to optimize battery power precisely and gently, ensuring efficient charging and extending battery life.

Billede 5.1: Visuel repræsentation af 9-ernetage charging process, showing how voltage and current are managed over time.
- Batteriafsulfatering: Uses pulse current to break down lead sulfate crystals in deeply discharged or sulfated batteries.
- Soft Start Charging: Gradually introduces current to the battery to prevent damage to very discharged batteries.
- Bulkopladning: Charges the battery at its maximum current until it reaches approximately 80% capacity.
- Absorption Charging: Charges at a decreasing current to bring the battery to 100% capacity.
- Vedligeholdelsesladning: Maintains the battery at full charge with a small, constant current.
- Batteritest: Monitors the battery to ensure it can hold a charge.
- Recondition Charging: Anvender en højere lydstyrketage to equalize cells and improve battery performance.
- Float & Maintenance Charging: Keeps the battery at optimal voltage for long-term storage.
- Small Current to Maintain Charging: Continuously monitors and provides minimal current to prevent self-discharge.
5.2 Current Selection
The charger offers three adjustable current levels (Low, Medium, High) to suit different battery capacities and charging speed requirements. Press the "Current" button to cycle through the options.

Image 5.2: Current selection options for different battery voltages and the Repair Mode function.
| Batteri Voltage | Lav strøm | Medium Current | Høj strøm |
|---|---|---|---|
| 6V | 2A | 5A | 10A |
| 12V | 3A | 13A | 26A |
| 24V | 5A | 8A | 13A |
Henstilling: Choose a current level appropriate for your battery's capacity. Higher currents charge faster but may not be suitable for smaller batteries.
5.3 Reparationstilstand
The Repair Mode (indicated by a wrench icon) uses small current pulse cycling to help restore and activate batteries that are sulfated or deeply discharged. This mode can run for up to 24 hours. Forsigtighed: This mode is not intended for repairing completely dead or physically damaged batteries.
5.4 Winter and Summer Mode (Temperature Compensation)
The charger automatically detects the ambient temperature and adjusts the charging voltage accordingly. This ensures optimal charging performance in both cold (Winter Mode) and warm (Summer Mode) environments, preventing overcharging or undercharging.

5.5 Automatic Full Stop and Maintenance
Once the battery reaches a full charge, the charger will automatically stop the bulk charging process and transition into a maintenance (trickle charge) mode. This prevents overcharging and keeps the battery at an optimal level for extended periods. For safety, the charger requires a reset (unplugging and replugging) for the next charging cycle.
6. Vedligeholdelse
- Rensning: Disconnect the charger from both AC power and the battery before cleaning. Wipe the exterior with a soft, dry cloth. Do not use solvents or abrasive cleaners.
- Opbevaring: Opbevar opladeren et køligt og tørt sted, når den ikke er i brug. Sørg for, at kablerne er pænt oprullet og ikke bøjet.
- Kabelinspektion: Periodically inspect the AC power cord and battery clamps for any signs of damage, fraying, or corrosion. Replace if damaged.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Opladeren tænder ikke. | Ingen vekselstrøm; løs forbindelse. | Ensure the AC power cord is securely plugged into a live outlet. Check the outlet with another device. |
| Oplader tilsluttet, men oplader ikke. | Incorrect battery connection; battery too deeply discharged; incompatible battery type. | Verify correct polarity of battery clamps (+ to +, - to -). Ensure battery voltage and type are compatible. If battery is extremely low, the charger may need a moment to detect it or may indicate an error if it's beyond recovery. |
| "FUL" displayed but battery not fully charged. | Battery capacity significantly degraded. | The battery may have reached its maximum charge capacity given its condition. Consider using Repair Mode if applicable, or replacing the battery if it no longer holds a charge. |
| Opladerens blæser larmer. | Normal drift under opladning med høj strøm. | The fan activates to dissipate heat during charging. This is normal. Ensure adequate ventilation around the charger. |
| Spark when plugging into AC outlet. | Inrush current. | A small spark upon initial connection to AC power can occur due to inrush current. While generally harmless, ensure connections are firm and avoid plugging/unplugging frequently. |
