...help!!? Electronics aboard a sailboat consume 25W when operated from a 12.6V source.
a) if a certain fully charged deep cycle lead acid storage battery is rated for 12.6V and 80amp-hrs, for how many hours can the electronics be operated from the battery without recharging? (the ampere hr rating for the battery is the operating time to discharge the battery multiplied by the current)
b) how much energy in kilowatt hrs is initially stored in the battery?
c) If the battery costs $85 and has a life of 250 charge discharge cycles what is the cost of the energy of the energy in dollars per kilowatt hr? (assume the cost of the recharging battery is 17cents per kilowatt hr and the battery charger has an efficiency of 85%)
