The light on my ICOM A14 charger was blinking orange/green and the charger was not charging the battery.

I took the battery off the radio, used a pencil eraser to clean the electrical contacts on the battery - they looked fine to me by the way - and now the charger light no longer blinks and it charges the battery.

By the way, I had looked in the A14 manual for info on this blinking light and found no reference to it.
