I have a Pyramid 3 farad capacitor with the digital display, I charged it with the bulb and car on until it stayed at 15.2v for a good 2 minutes. After that, I hooked it up to the amp, and to the battery w/o the bulb of course. and then i play my music or w/e and turn off the car, go inside for about an hour and I come back outside, and the digital display is still on 13.1v and it doesn't turn off, why?
