4. Enstalasyon
To set up your XTAR MX4 charger:
- Konekte pouvwa: Use the provided USB A to C cable to connect the charger to a 5V 2A USB power adapter or a compatible USB power source. The charger's indicator lights will illuminate briefly upon connection.
- Plasman: Place the charger on a stable, flat, and non-flammable surface, away from direct sunlight or heat sources.
5. Operasyon Enstriksyon
The XTAR MX4 features intelligent battery recognition and independent charging slots.
5.1 Mete batri yo
Carefully insert one or more rechargeable batteries into the charging slots, ensuring the positive (+) and negative (-) terminals align correctly with the markings on the charger. The spring-loaded contacts accommodate various battery lengths.

5.2 Pwosesis chaje
Upon insertion, the charger will automatically detect the battery type and initiate the appropriate charging mode. The LED indicator above each slot provides charging status:
- Red Light (Solid): Batri ap chaje.
- Red Light (Slow Flash): Battery identification/activation in progress.
- Red Light (Rapid Flash): Recovery failed or an anomaly occurred.
- Green Light (Solid): Charging is complete or no battery is present.
The charger employs an intelligent charging strategy (TC-CC-CV for Li-ion) to optimize battery lifespan and performance, automatically stopping when fully charged.

NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Chargeur a pa limen. | Pa gen koneksyon kouran oswa kab/adaptè a gen pwoblèm. | Ensure the USB cable is securely connected to both the charger and a working 5V 2A power source. Try a different USB cable or power adapter. |
| Battery not charging (Red light flashing rapidly). | Battery inserted incorrectly, battery is severely over-discharged, or battery is damaged. | Re-insert the battery ensuring correct polarity. If the issue persists, the battery may be too deeply discharged for recovery or is faulty. Try a different battery. |
| Chaje se dousman. | Insufficient input power or charging too many batteries at high current. | Ensure your USB power adapter provides at least 5V 2A. The charger provides 1A for two slots or 0.5A for four slots. Charging four batteries simultaneously will result in 0.5A per slot. |
| LED is green but battery is not fully charged. | Poor contact with battery terminals or battery is not rechargeable. | Adjust the battery position to ensure good contact. Verify that the battery is indeed a rechargeable type compatible with the MX4. |
