Frequently Asked Questions
What’s the best car battery brand in the UK?
Bosch, Varta, and Yuasa are the top three. Varta actually manufactures batteries for many other brands (including Bosch S4/S5), so quality is very consistent across premium brands.
How much should I spend on a car battery?
£60-100 for a standard or EFB battery, £100-180 for AGM. Avoid the cheapest options (under £50) as they typically have lower CCA and shorter warranties.
Is Halfords own-brand battery any good?
Halfords batteries are manufactured by Yuasa — they’re decent quality for the price. However, the premium Yuasa, Bosch, and Varta ranges offer better CCA and longer warranties.
How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
