Operating: Charging and Usage
Initial Charge
For optimal performance, it is recommended to fully charge the batteries before their first use. Place the headphones with the newly installed batteries onto their compatible charging base or connect them to a suitable charger as per your headphone's instructions.
Regular Charging
Recharge the batteries when your headphones indicate low power or when performance diminishes. Always use the charging equipment provided with your wireless TV headphones or a compatible Ni-MH battery charger.
Usage
Once charged, the batteries will power your headphones. The 700mAh capacity provides extended usage time. Battery life will vary depending on headphone model, volume levels, and usage patterns.
Maintenance and Storage
- Cleaning: Keep battery terminals clean. Use a dry cloth to wipe off any dirt or corrosion.
- Storage: If storing the batteries for an extended period, charge them to about 50% capacity and store them in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Over-Discharge: Do not allow batteries to completely discharge for prolonged periods, as this can reduce their lifespan.
- Avoid Over-Charge: While Ni-MH batteries are generally tolerant to overcharging, using a smart charger designed for Ni-MH batteries is recommended to prevent excessive heat and prolong battery life.
