Just do what you think is best with that fancy AGM battery. Don’t consult the manufacturer, and don’t charge it properly while the car is off the road. 100% my fault. I totally screwed this one up.
Do yourself a favor, don’t fuck this up. Learn from me! If I had spent the extra money for a tender or charger from Braille when I had bought the battery, I wouldn’t have had a problem. Instead I hooked up my old 20 dollar battery tender from Walmart to it, and here we are.
