Hello. New here. Having issues. Up until yesterday battery was fine. Was at work, took quick lunch break. Possibly left headlights on. When break was over tried to start car. Dead. Just light clicking. Made me use keyfob to try to start it. Mirrors folding in and out. Wouldn’t start. Wound up using my Makita drill battery to start my car. Let car run for a while to charge car battery. Once i turned it off, tried to turn back on. Nothing. Had to jump battery five times yesterday. Why would it be just fine, then nothing. Won’t take a charge at all. Am i doing something wrong? The battery is not that old. And went from working fine to not working at all in 15 minutes.
