Anybody know more about Priority Start or have one? http://batterymart.com/prioritystart.asp Might be simpler solution than a second battery for *light* accessory use when used with Optima. They claim aux power doesn't disconnect battery.
From their FAQ: PriorityStart! is a computer-controlled electromechanical system (handles 1000 cranking amps) that constantly monitors the vehicle's electrical systems and battery power level. If, when the vehicle ignition is turned off, it detects a drop in battery voltage to a factory-set level, (slightly below 12 volts) then it automatically disconnects the battery, leaving starting power in the battery. PriorityStart! ! automatically reconnects the battery (any load greater than 100 microvolts) when the ignition key is turned on. No buttons or switches to operate. No need for a battery booster unit. PriorityStart! ! is totally automatic! What if I want to leave the hazard lights on with the ignition switch turned off? Even though the engine is not running, if other electrical sources are operating on the vehicle, such as hazard lights, flashing emergency lights, strobes, auxiliary power supplies, PriorityStart! reads this as engine NOISE and will not disconnect the battery.
