Exide’s EB442 and Bosch’s S4 001 (often listed as 063) sit in the mainstream lead acid starter battery bracket, the sort commonly fitted to older petrol cars and smaller diesels. They compete with other everyday OE style replacements from Varta, Yuasa and Halfords, focusing on reliable cold starts rather than stop start support. If your current battery is struggling on frosty mornings, a 420A cold cranking rating is the figure that matters most, it points to how confidently it can spin the engine over when it is cold.

Is this the right battery for your car?

Check your existing battery’s code and dimensions before buying. “063” is a common UK fitment size, but terminals and hold down style still need to match. Also note that these are standard flooded batteries, so they are not suitable replacements for AGM or EFB units used in many stop start cars.
