View Full Version : Bad Car Battery = Slow car

Can a bad car battery make your car run slower ?
(Like at wide open throttle.)
I am thinking that it can, maybe because of not enough amperage for the ignition system ?

Arguably if the batt is low the coil would have to work harder in order to produce enough voltage to fire. But you'd have to be awfully low for multiple coil packs to really take that big a hit

But what if the car battery's voltage is ok; but the car battery doesn't provide any real power/amperage ?
(Like almost not enough power/amperage to start the car.)
