Chapter 1, Problem 1.30P
The electronics aboard a certain sailboat consume 50 W when operated from a 12.6-V source. If a certain fully charged deep-cycle lead acid storage battery is rated for 12.6 V and 100 ampere hours, for how many hours can the electronics be operated from the battery without recharging? (The ampere-hour rating of the battery is the operating time to discharge the battery multiplied by the current) How much energy in kilowatt hours is initially stored in the battery? If the battery casts $75 and has a life of 300 charge-discharge cycles, what is the cost of the energy in dollars per kilowatt hour? Neglect the cost of recharging the battery.
