Not sure what happen to my first post but it disappeared. I got 3 batteries one I know is a ego long one with a counter on bottom. Long story short I can't get a full charge. My light never turns green on my two shorter batteries I charged them by plugging into wall the light first turns green then goes to red. I let it charge the small one (half the size of the large one with cou ter on bottom) for 5 hours still no green light. I took it off not wanting to overcharge it but even with the bigger batt it still don't turn green. My brother said it would take 1 1/2 hours to charge. What could be the issue here if any?
