i have a standard 2003 td5 with a 110amp per hour battery.
if i run a 45w 12v coolbox on it how long should it last.
or put another way how long before there is not enough umph in the battery to start the engine.

i guess there maybe to many variables for a specific answer.

also is there a permenant live and earth at the socket end of a 12s socket ? if so if i look from the flap end which are they.

thanks

Yer cool box draws about 4A, so theoretically yer battery will last 110/4 = 27.5 hrs.
However, your batery is unlikely to still have it's absolute full capacity and may not be fully charged at the start. You will also need sone juice to start your engine.
I wouldn't rely on it lasting any more than 12 to 15 hours to be honest.
 
oh, and yer towbar wiring info is in the common questions bit somewhere (Pikey's font of all knowledge?)
