12volt tv combi

[barneyted]

does anybody know a tv using 20watts on a lesuire battery of 110 how long will it last?

Assuming the battery is fully charged ..

The calculation,

20 watt div by 12v = 1.66 A

As you should never discharge more than 50%, a 110ah battery has a useful capacity of 55ah

Time in hr = 55ah div 1.66A = 33 hrs

You will have square eyes after 33 hours of tele
