Tips to Extend the Life of your Radio Shack Cordless Phone Battery

  • Proper charging will help to keep your cordless battery operating at full power.
  • Remove the phone from the charger when charging is complete - continuous charging in the cradle will dramatically reduce the life of the battery.
  • Store the phone and battery in a dry place at or below room temperature, without exposure to direct sunlight.
