Got a used lumix camera that came with this charger. It's really plug n play, but I want to know what the led lights indicates. It turns green when plugged in the wall or in the car. Light turns red when a battery is installed for charging. Then after a few minutes it flashes between green & red, then steady green. It seems like it stops charging pretty quick, the camera power level is at full but it dont last long. The new charger takes longer to charge the same batteries but they last longer too.
