4.2 Charging the Battery

The walkie talkies come with a 1500mAh Li-ion rechargeable battery. There are two primary charging methods:

  • Interphone Charging: Place the entire walkie talkie unit into the charging base.
  • Battery Charging: Remove the battery pack from the walkie talkie and place only the battery pack into the charging base.

Connect the USB cable from the charging base to a compatible USB power source (e.g., PC, car charger, wall adapter, power bank). The charging indicator light will be red during charging and turn green when fully charged. A full charge typically takes 2-3 hours, providing 18-24 hours of continuous use.
