So in practice the difference should be negligible as the average current pumped into the speakers will be much higher.

Hi Maninder
For reference my DAB car radio is incorporated into an Xtrons (Chinese) DD and the car battery is a 77Ah Exide Premium - 18 months old.
As previously mentioned I'd also be interested to know what drain watching TV on the DD has on the battery without the engine running.
So, I can safely park up for 1-2 hours using either mode (DAB/TV) without fear of battery failure?
