This is one of the best capacitors I have owned and definitely worth every penny. It looks just as good as it performs and certainly takes most of the strain off of your alternator and battery. It installs quick and neat and holds a steady 14.4volt charge once your vehicle is on and the digital display adds a nice touch. I did not notice any cons and if you want the best price then you are already in the right place.

Ring Terminals
Use these ring terminals to connect the power and ground cable to the capacitor. The more surface area the ring terminal has to the capacitor's terminal, the better the connection will be.
