How long can a brand new car battery power the ff:?

Question

I have a small room and I am thinking of powering it using only a car battery. How long do you think can a car battery last if it powers these things:

1 laptop

1 electric fan

1 florescent light

All at the same time.

Also if you have any suggestions how to actually do this, kindly tell me the basics or provide me a link. Basically I just want to a car battery to have an AC outlet so I can plugin the items above. Thanks.

Answer 1

You'd be better off running an extension cord to power these things. Cars have an alternator that charges the battery when the car is running and supplies power for all the accessories. The battery generally only is used to start the car.

Answer 2

I think you should assume "Minutes"

   To do what you want, you'd need a converter, certainly should have a battery charger.

   I could analogize it this way. Think of a Honda CRV, with the option of AC outlets for camping, etc. The battery, which powers the vehicle systems also has an alternator, that aids in recharging. The AC outlets use a converter for 12 v to 120v.

Answer 3

You need a 12 volt DC to 120 volt AC inverter.

One thats rated 2000 watts should do it.

Without some form of recharging, as power is being drawn,

it will only last 3 to 6 hours.

Answer 4

no car battery will do what you want. even a deep cycle can not give you the voltage you need.
