btw anybody know the amp output of a 12V car battery??
well... i assume that you know that a car battery o/p is 12VDC.. maybe 13-14.4 VDC depending on how good is your battery.... however, voltage don't really mean anything without current...
a good and fully charged car battery can deliver at least 30 to 50 AMps when we initialy start our car... during the cranking of the the key, we actually engaging the solenoid to turn on the starter... this process will draw at least 30 to 40Amps. But, It's justs for a couple of seconds untill the car engines starts... then when we back of the key, this will disengage the starter... so... less current will be drawn by others electronics..
Hope this explain a bit..
