Ultracapacitors, Are they worth it?,...

the #1 complaint of Maxwell's Ultracapacitor
"it sucks sitting in a shop for extra half hour, after a fuel filter change, because the thing has to recharge after cranking to get the prime back (pre-filled fuel filter, no manual primer pump on N14)"

Capacitor charges from battery voltage and steps up the voltage to 16VDC, it usually takes 15 minutes of charging then you can crank again.
