I am sorry if I overlooked this answer somewhere else. I just purchased my first ft-60 and wondered if it was best to let the battery "completely drain" before recharging, and just re-charge when the battery indicator shows low?? Someone mentioned letting it "completely drain" before re-charging - left it on for about 20 minutes after the low battery indicator started flashing .? I just want to do what is best for the battery.? Also, approx. what low voltage reading will trigger the low battery indicator? ? Thank you. -Scott
