Setup

1. Unpack: Carefully remove all components from the packaging.
2. Inspect: Check the charger and batteries for any visible damage. Do not use if any damage is observed.
3. Placement: Place the charger on a flat, stable, and dry surface, away from direct sunlight and heat sources. Ensure there is adequate space for ventilation.

Operating Instructions: Charging Batteries

Follow these steps to charge your Panasonic Ni-MH AA batteries:

1. Insert Batteries: Open the battery compartment cover (if applicable) or carefully insert the AA Ni-MH batteries into the charging slots of the BQ-321 charger. Ensure that the positive (+) and negative (-) terminals of the batteries align correctly with the markings on the charger. Incorrect insertion can prevent charging or damage the batteries/charger.
2. Connect to Power: Plug the charger's power cord into a standard electrical outlet. The charger is designed to operate with an input voltage of 240 Volts.
3. Charging Indication: The charger typically features indicator lights (e.g., LEDs) for each charging slot. When batteries are correctly inserted and charging begins, the indicator light for that slot will illuminate (e.g., red). Once charging is complete, the light may change color (e.g., green) or turn off, depending on the charger model.
4. Charging Time: Charging times can vary based on the battery capacity and their current charge level. Refer to the battery's specifications for typical charging durations. Do not overcharge batteries beyond the recommended time.
5. Remove Batteries: Once charging is complete, unplug the charger from the power outlet. Carefully remove the charged batteries from the charger.

Note: The charger is specifically designed for Ni-MH batteries. Do not attempt to charge other battery types.

Maintenance

• Cleaning: Disconnect the charger from the power source before cleaning. Use a soft, dry cloth to wipe the exterior of the charger. Do not use liquid cleaners or solvents.
• Storage: Store the charger and batteries in a cool, dry place, away from direct sunlight and extreme temperatures. For long-term storage, it is recommended to store Ni-MH batteries with a partial charge.
• Battery Care: Avoid fully discharging Ni-MH batteries frequently, as this can reduce their lifespan. Recharge them when they show signs of low power.
• Disposal: Do not dispose of batteries in household waste. Follow local regulations for proper disposal of rechargeable batteries, which often involves recycling at designated collection points.

Troubleshooting

If you encounter issues with your Panasonic BQ-321 charger, refer to the following common problems and solutions:

• Batteries not charging / Indicator light not on:
  • Ensure the charger is securely plugged into a working power outlet.
  • Verify that the batteries are inserted correctly, aligning the positive (+) and negative (-) terminals.
  • Confirm that the batteries are Ni-MH type. The charger cannot charge other battery chemistries.
  • Check if the batteries are severely over-discharged or faulty. Try charging a different set of known good Ni-MH batteries.
• Charger or batteries feel hot during charging:
  • It is normal for batteries and the charger to become slightly warm during charging. However, if they become excessively hot, immediately unplug the charger and remove the batteries.
  • Ensure the charger is in a well-ventilated area and not covered.
  • If excessive heat persists, the batteries or charger may be faulty. Discontinue use and contact support.
• Batteries do not hold a charge after charging:
  • Rechargeable batteries have a limited lifespan. If batteries no longer hold a charge, they may have reached the end of their service life and need to be replaced.
  • Ensure the charger completed the charging cycle (indicator light changed/turned off).
