Are the batteries from a Chevy pick up interchangeable with Ford pickup?

No, Chevy and Ford pickup truck batteries are generally not interchangeable. While they might be the same voltage (usually 12V), the battery size (group size), terminal placement (positive on the left or right), and mounting hardware are usually different between the makes and even models within a make. Trying to use the wrong battery could lead to poor performance or even damage to the vehicle. Always check your owner's manual or the battery itself for the correct group size before purchasing a replacement.
