Hello DavyBoy,

Welcome to CPF.

I believe your charger flashes red and green while charger and green when the charge has completed.

Yes most of the UF chargers will be green when you plug them in and then turn red when you put in a battery that needs charging. They stay mostly red while charging but about once every second or two you will see a brief green flash. This I believe is the circuit checking the voltage on the battery. When it turns steady green it is charged and is best to remove it right away. If you have a voltmeter check it to make sure your charger is not charging them over 4.2 volts. Anything much over that will shorten their life.

:welcome:
