[QUOTE="jarance, post: 140971, member: 21"] Let me see how shall I put it.. For a normal battery, the rating is about 90AH (Amp Hour). That means it can maintained a load of 90 amp (when fully charged) for one hour before the battery is completely drained. Assuming your battery is about 80% fully charged. That means you will have about 72AH. (In most case this is true if your battery is old). If you have your CCFL and parking light on, the consumption is about 50W. That means the current is about 50W/12V=4 Amp (Using Ohm Laws) So, with a consumption of 4 Amp, the battery will be fully discharged in 72/4=18 Hrs. But take note the starter need about 11.5Volt in order to work properly. I don't have the discharge curve of the battery with me so I cannot determine the maximum time you can have the CCFL and parking light ON before it rendered the battery useless for starting. [/QUOTE]
