8. Maintenance

• Cleaning: Disconnect the charger from power before cleaning. Use a soft, dry cloth to wipe the charger's surface. Do not use abrasive cleaners or solvents.
• Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Avoid Impact: Protect the charger from drops or heavy impacts, which can damage internal components.

9. Troubleshooting

• Charger Not Powering On:
  Ensure the power cable (AC or Micro USB) is securely connected to both the charger and the power source. Try a different power outlet or USB power source.
• Battery Not Charging / Error Display:
  Check that the battery is inserted with correct polarity. Ensure the battery is a compatible rechargeable type (refer to Section 7). If the battery is severely over-discharged (0V), the charger's 0V Activation Function may attempt to revive it; allow some time for this process. If the issue persists, the battery may be faulty.
• Slow Charging:
  Ensure you are using a power source capable of delivering sufficient current (e.g., a 2A USB adapter for Micro USB input).
