A car owner forgets to turn off the headlights of his car while it is parked in his garage. If the 12.0V battery in his car is rated at 150.0 A ยท h and each headlight requires 41.4 W of power, how long will it take the battery to completely discharge?

charlie,
Calculate the amperage of the lights:
watts/volts= Amps.
Then divide the battery's capacity by the answer.
