Review on Boost Your Car's Audio Performance with NIPPON ACAP2000 2.0 Farad Power Capacitor by Elmito Yeager

Used it about 2 months. After opening everything looked fine, including all the necessary hardware and a resistor for charging. However, it took a while for the display to turn on to even indicate that it was charging. Some time showed a charge. Now the display doesn't show up at all. Still connected. It's not dead because I don't have electrical issues or my amp doesn't heat up and my lights don't dim due to my system, but there just isn't a display to visually indicate it's working.
