4. הגדרה וחיבור
Follow these steps to safely connect the GYSFLASH 12.12 charger to your battery:
- הכן את הסוללה: Ensure the battery terminals are clean and free of corrosion. If charging an in-vehicle battery, ensure the vehicle's ignition is off and all accessories are disconnected.
- התחבר לסוללה:
- חבר את אדום (+) charger clamp/טרמינל ל- חיובי (+) מסוף סוללה.
- חבר את שחור (-) charger clamp/טרמינל ל- שלילי (-) מסוף סוללה.
- For in-vehicle batteries, if the battery is not grounded to the chassis, connect the black (-) clamp to the negative (-) battery terminal. If the battery is grounded to the chassis, connect the black (-) clamp לשלדת הרכב הרחק מהסוללה וצינור הדלק.
- התחבר לכוח: Plug the charger's AC power cable into a standard electrical outlet. The charger will power on.
- בחר מצב: Press the mode selection button to choose the appropriate charging mode (see Section 5).
To disconnect, first unplug the charger from the AC outlet, then disconnect the black (-) clamp, ואחריו ה-(+) אדוםamp.

5. מצבי הפעלה
The GYSFLASH 12.12 offers several operating modes to optimize charging for different battery types and conditions. Use the mode selection button to cycle through these options.
- Normal Charge Mode: Standard charging for most 12V lead-acid batteries (WET, MF, Ca/Ca, GEL).
- מצב AGM: Specifically designed for cold weather charging (below 5°C) and for Start & Stop batteries (EFB & AGM types). This mode adjusts charging parameters for these specific conditions.
- מצב רענון: Used to recover deeply discharged batteries. This mode attempts to recondition batteries that have been left discharged for extended periods.
- מצב אספקה: Transforms the charger into a stabilized power supply. This mode is useful for:
- Maintaining battery health during vehicle demonstrations in showrooms.
- Preserving vehicle memory settings (e.g., radio codes, ECU data) during battery replacement.
The charger also features an Optimized Maintenance Charge, allowing it to remain plugged in indefinitely during winter months to maintain battery health without overcharging.

6. 8-Step Intelligent Charging Curve
The GYSFLASH 12.12 utilizes an advanced 8-step charging curve to ensure efficient, safe, and complete charging, maximizing battery lifespan and performance. The external temperature sensor automatically adjusts this curve based on ambient conditions.
- אָנָלִיזָה: Assesses battery condition and initial charge level.
- הִתאוֹשְׁשׁוּת: Initiates a gentle charge for deeply discharged batteries (SOS Recovery for batteries >2V).
- מִבְחָן: Checks battery's ability to accept charge.
- דה-סולפטציה: Applies a pulsed charge to break down lead sulfate crystals, restoring battery capacity.
- תַשְׁלוּם: Bulk charging phase, delivering maximum current until the battery reaches approximately 80% capacity.
- קְלִיטָה: Gradually reduces current while maintaining voltage to bring the battery to 100% charge.
- לְרַעֲנֵן: (If selected or needed) Further reconditions the battery.
- מטען צף: שומר על הסוללה בטעינה מלאה עם עוצמה נמוכה וקבועהtage, preventing self-discharge.

7. תחזוקה
Proper maintenance ensures the longevity of your GYSFLASH 12.12 charger and the batteries it charges.
- טיפול במטען:
- שמור על המטען נקי ויבש. נגב בעזרת מטלית רכהamp בַּד. אין להשתמש בממיסים.
- אחסן את המטען במקום קריר ויבש כאשר אינו בשימוש.
- בדוק כבלים וחיבוריםamps regularly for damage. Replace if necessary.
- טיפול בסוללה:
- ודא שהדקי הסוללה נקיים וללא קורוזיה.
- For conventional lead-acid batteries, check electrolyte levels periodically and top up with distilled water if needed (do not overfill).
- For optimal battery health, use the maintenance charge feature during long periods of inactivity.
8. פתרון תקלות
If you encounter issues with your GYSFLASH 12.12, refer to the following common problems and solutions:
| בְּעָיָה | סיבה אפשרית | פִּתָרוֹן |
|---|---|---|
| המטען לא נדלק. | No AC power; faulty power cable. | Check AC outlet and power cable connection. Try a different outlet. |
| Charging indicator not active. | Incorrect battery connection; battery voltage too low; incorrect mode selected. | Verify positive/negative connections. Ensure battery voltage is above 2V for recovery. Select appropriate mode. |
| Error LED illuminated. | Polarity reversal; short circuit; internal fault. | Disconnect charger, check connections for correct polarity. Inspect cables for damage. If error persists, contact support. |
| הסוללה לא טעונה במלואה לאחר זמן ממושך. | Battery deeply discharged or sulfated; battery capacity too large for charger; faulty battery. | Try "Refresh" mode for deeply discharged batteries. Ensure battery capacity is within charger's range (1.2-250 Ah). Test battery condition. |
| Charger automatically stops. | Battery disconnected; power cut; battery fully charged. | Check battery connections. The "Auto Restart" feature should resume charging after a power cut. If battery is full, this is normal operation. |
If the problem persists after attempting these solutions, please contact GYS customer support.
