Key Factors When Choosing a Car Battery
Choosing the right car battery depends on your vehicle’s requirements and driving habits. Here’s what to consider:
✅ Battery Size & Fit
Ensure the battery fits your vehicle's tray and has the correct terminal layout.
✅ Cold Cranking Amps (CCA)
Higher CCA provides better cold-weather starting performance—important for UK winters.
✅ Amp Hours (Ah)
Higher Ah means more stored power—useful for cars with lots of electronics.
✅ Battery Technology
Refer to your owner’s manual to see if your car requires AGM or EFB technology.

Most car batteries last between 3 and 5 years, depending on usage, climate, and vehicle type.
