I have not really checked them like that and taking them off but on either end they show corrosion and the reading when connecting my multimeter shows 14.2 when running but if I live it connected and drive for two or three days it will end up dieing out on me. And not only that the battery’s mess up inside. Since I got a new one from Orielys it has warranty and I’ve changed it to due to bad cells inside like the car messes up the battery too, don’t know why

if you could call me i could explain more at 956-754-1413 Romeo I would really appreciate it
