Hope some can help with this. Ive had to buy and in car cctv cos some failed lab experiment is keying my car. Ok so what I need to know please, the cctv is 5v through the ciggy lighter socket and the camera has a nokia phone battery rated at around 850 mah......I think. I know absolute zero about electrics, so can anyone suggest how long the camera could run for in hours before flattening my battery enough to make car a non starter? Last thing I want is to be stuck somewhere. Is there a calculation ? Also maybe buy a jump starter from halfords and run it off that?
Just need to know if I had it plugged into car battety how long I could leave it going before getting into non starting situation?
Car is 330ci and battery is couple months old. cadmium heavy duty type.
Cheers if u can advise. Got to catch this idiot.
