Battery Tender Junior Flashing Green Light. The Battery Tender Junior 12v charger has a single light that will shine either red or green. Wait no more than 3 seconds for solid red light.
I have one older Battery Tender Jr. That is chugging along nicely but two of the newer ones started acting up. Below describe the indicator lights and what they mean.
I also picked up the cigarette lighter adapter.
