stranger12 Posted May 21, 2016 Share Posted May 21, 2016 Hi guys Changing my r34 battery cable , what amp rating should it be and what brand is the high quality stuff? I have seen 30 amps but think that will not be sufficient Link to comment https://www.sau.com.au/forums/topic/464924-car-battery-cable/ Share on other sites More sharing options...
t_revz Posted May 21, 2016 Share Posted May 21, 2016 what section are you replacing? the longer the piece the thicker it should be 30 amp cable is 4mm2 and is not battery cable, if your referring to cables from the battery to chassis, or terminal block then they should be 35mm2 at a bare minimum (thats probably factory size) but i wouldnt use under 50mm2 cable on my own car. with my battery being in the boot i have the factory 35mm2 cable plus a 70mm2 cable strapped alongside it, with 70mm2 cables between the alternator,starter motor and junction block Link to comment https://www.sau.com.au/forums/topic/464924-car-battery-cable/#findComment-7730762 Share on other sites More sharing options...
stranger12 Posted May 21, 2016 Author Share Posted May 21, 2016 Planning to relocate the battery Does 70mm means it is 7cm in thickness ? That would be huge Link to comment https://www.sau.com.au/forums/topic/464924-car-battery-cable/#findComment-7730779 Share on other sites More sharing options...
Ben C34 Posted May 21, 2016 Share Posted May 21, 2016 Its the surface area of the cable. Maths will let you figure out the diameter. A 30amp cable like you suggested would melt instantly Link to comment https://www.sau.com.au/forums/topic/464924-car-battery-cable/#findComment-7730784 Share on other sites More sharing options...
stranger12 Posted May 21, 2016 Author Share Posted May 21, 2016 Sure what is the standard amp for gtt? Any brand that you guys prefer What happens when the cable is 200 amp and you have a cold cranking amp of 500 ? Is it because it is milli seconds it will be quick and not melt cable? What happens when the car does not crank over and you keep ignition open?

Dose Pipe Sutututu Posted May 21, 2016 Share Posted May 21, 2016 Get 2ga or 0ga audio cable. 30 amp cable your suggesting will turn into a heater element and torch your car. Please also run an appropriate fuse as close to the battery as possible 1 Link to comment https://www.sau.com.au/forums/topic/464924-car-battery-cable/#findComment-7730837 Share on other sites More sharing options...
