I thought this 12v battery was AFU inside cause I would try to charge it and nothing would happen.
So I put a meter on it for a volt check and found out it was reading a - 12.5 volts.
Seems I remember if a battery was dead and u hooked up a charger in reverse it could be charged up in reverse.
How it got that way I don't know, I pulled it out of my trailer for the winter and it seemed to be dead.
Question is....can it be put back to normal ?
