I purchased a battery kit from batteryjunction.com and it came with 4 900mah 3v batteries the charger and a car adapter. After charging the batteries the first time everything worked fine but now I need to recharge them and when I put the batteries into the charger, it keeps flahing red green red green over and over. The instructions say that with the charger is plugged in it will have green light which it does. Then when you put the batteries into it it should change to red and then to green when the batts are charged. When I put the batts in it flahes red green. Anyone else have this issue?
