Review on ⚡ Black Stinger SPC505 Pro Hybrid 5 Farad Capacitor by Jason Sundstrom

Does a great job of keeping backup power/amp constant while draining secondary battery when engine is not running. Installation instructions are vague (treat the failed diode as simple and charging/discharging is easy), we were back in the vaca in 10 days, started the car, turned on the amps and 14.2v. This is not a dual purpose battery alternative. a Big 3 battery and HO generator upgrade. This is a power reserve boost if you are having trouble adjusting your headlights/taillights/etc. to dim. THIS WILL NOT FIX AND WILL NOT BE ANOTHER CAP! Yellow Cap, Mech Man and 0/1 BIG 3 is your answer. Don't spoil a reliable product that works as it should!
