Approx how much does a good new battery cost and does the make of the car affect type of battery you buy? In other words can a battery fitted to all makes of car. Mine is a ford focus.
Battery specs vary depending on the engine size, fuel type, and equipment level. Use the Halfords tool, or take a look at your current battery to get the specs, then shop around. You'll probably find a local motor factor who is significantly cheaper than the likes of Halfords.
