The BC-144N charges a Ni-Cd or Ni-MH battery pack in approx. 1–2.5 hrs. It comes with the 120 VAC BC145A/SA wall adapter. It also includes the AD99N spacer. The orientation of this spacer allows you charge the battery alone, or while attached to the IC-U82.
The Icom BC-144N-51 has a built in LED that glows orange during rapid charging or green when the rapid charge has finished. While the LED is green it will continue to trickle charge Ni-Cd or pulse charge NiMH. The LED will blink red if the inserted battery pack or the charger has a problem. The battery must be removed from the charger to stop charging. Always remove after 15 hours.
