Car batteries come in many different shapes, sizes and capacities, and they differ between old and new cars, but choosing the right one doesn’t have to be problematic. We stock a range of high quality 017 car batteries to suit your requirements – all you need to know is the model number that is stated in your manual. One common misconception is that 019 car batteries are suitable and better quality replacements for 017s because of their higher capacity, but this is not the case. It is recommended that you consult a specialist to ensure that you purchase exactly the right battery for your car.
