I'm not sure mate, my coming home headlights don't work when the car is below 11.8V and the camera has cut out many times at what is supposed to be 12.1V but in reality is 11.8V when it was cold - is yours a petrol or diesel?
The one time I didn't use power cut off and it sat running on the timer I almost couldn't start the car and it took a few mins to get it to turn over - the battery was new in April last year and to be honest the run time seems to be increasing as the weather is warming up but as we still get frost overnight I'm not risking it just yet as I need to be able to get to client sites on time.
Too risky for me just yet - plus workarounds are just an excuse for Sungmoon to delay the fix - the Chinese New Year is putting a stop to things for the next week so fingers crossed they can get on the case soon afterwards
