I'm charging my small ATV battery with the plug with two alligator clips. The plug has a green light and a red light. After just a couple of minutes both lights are green and red. There is no change. How long should I charge this thing? Thank you.
If it is a small maintainer/charger the battery may be too far discharged for it to work. May need to try a higher amp charger. Some larger chargers have an "activate/start" setting that will often revive a totally dead battery to the point a maintainer can take over.
