i have a 1000 watt light bulb and i need it to last 12 hours on batteries. i figure car batteries are the best. how many batteries would i need to have it last 12 hours?

 

1000 watts for what? NY have another blackout?

 

its for ice fishing. need light!!

 

theres equations for this kind of thing but I don't know them but for 12 hours your talking like 1 per hour atleast

 

Can you bring a generator or a long extension cord?

To power 1000 watts for 12 hours at 12volts means you need 1000AH(amp hours) at 12 volts.

The biggest svr battery puts out 100AH and weighs 72 pounds. You will need 10 of these

 

Make that 13-15 I forgot to account for battery loses due to internal resistance.

 

eep. **** that idea. haha. ill just have to look into a generator then. thanks guys.

 

honda makes some sweet generators. I think they could cover the power you are looking for in a small carriable genny.
