Frequently Asked Questions
Are expensive car batteries worth it?
Yes, for Start/Stop vehicles and commercial use, premium batteries are worth the investment. They last longer (5-7 years vs 3-4 years), handle frequent cycling better, and come with longer warranties. For standard vehicles, mid-range brands like Yuasa offer excellent value without the premium cost.
Can I fit a higher capacity battery than the original?
Usually yes, but with caveats. Higher capacity batteries must physically fit in the battery tray and match the technology type (AGM/EFB/standard). For vehicles with Battery Management Systems, you may need to update the coding to reflect the new capacity. Always verify physical dimensions before purchasing.
Which battery brand is most reliable?
Varta and Bosch consistently rank highest for reliability and performance, particularly for Start/Stop vehicles. However, Yuasa and Exide also offer excellent reliability at more competitive prices. Choose based on your vehicle type and budget.
Do I need to match the exact battery brand?
No, you don't need to match the brand, but you must match the technology type (AGM/EFB/standard), capacity (Ah), and size code. As long as the replacement battery meets or exceeds the original specifications, any reputable brand is acceptable.
How much should I spend on a car battery?
Expect to spend £120-£250 for premium AGM batteries, £80-£150 for EFB, and £50-£120 for standard flooded batteries. Start/Stop vehicles require AGM or EFB, so budget accordingly. Premium brands cost more but offer longer lifespans and better warranties.
What's the difference between budget and premium batteries?
Premium batteries use higher-quality materials, better plate construction, and superior manufacturing processes. This results in longer lifespans, better performance in extreme conditions, stronger warranties, and better charge acceptance. Budget batteries may work for low-use vehicles but fail quickly under demanding conditions.
