It is doing something as the basic monitor inside is lighting up indicating something is going in. We are, of course, thinking of buying a TV but are concerned that the power required will drain the leisure battery very quickly - we don't intend to use camp sites very often and therefore will not have hook-up. Is there any way we can improve the 12v supply?
We are newbies but we understand it to depend on various factors such as the Battery size and TV power usage.

Our 12v TV runs at about 4 amps, and our leisure battery is 113 ah, which in theory means we could watch the TV for 28 hours. This assumes that you have no other 12 volt appliances running.

In Reality we found that our leisure battery can last about 3 days, that is with the TV on for a couple of hours each night, lights and kids charging DS's etc. We have just added a 2nd leisure battery and plan to purchase a solar panel next so we can manage for long trips away.
