Not every car battery is built the same way, and the differences aren’t just about price — they reflect real construction differences suited to different electrical demands.
Conventional flooded lead-acid
This is the traditional, most common battery type: lead plates submerged in a liquid electrolyte. It’s the standard, reliable choice for most vehicles without start-stop systems or unusually heavy electrical loads, and it’s typically the most affordable category. For an ordinary passenger car doing ordinary driving, a quality conventional battery is a perfectly correct choice, not a compromise.
AGM (Absorbent Glass Mat)
AGM batteries hold the electrolyte in a fiberglass mat rather than as free liquid, which makes them more resistant to vibration, allows them to be mounted in more orientations, and generally gives them better tolerance of deep discharge cycles and heat. They’re commonly specified as original equipment for vehicles with start-stop systems (which cycle the battery far more often than a conventional engine) and vehicles with heavier electrical loads from added accessories. AGM batteries cost more than conventional ones, and that cost reflects genuinely different construction, not just branding.
EFB (Enhanced Flooded Battery)
EFB sits between conventional and AGM: it’s still a flooded design but with reinforced plates and construction that gives it better cycling durability than a standard flooded battery, at a lower cost than AGM. Some start-stop vehicles are specified for EFB rather than AGM, depending on the manufacturer’s electrical load calculations.
How to know which one your car needs
The correct starting point is always what your vehicle manufacturer specifies — check your owner’s manual or the label on your current battery, which lists its type. If your car has a start-stop system (the engine automatically switches off at traffic stops), it almost certainly needs AGM or EFB, not conventional — fitting a conventional battery in a start-stop vehicle typically leads to premature failure because it isn’t built for that duty cycle. If you’re unsure what your current battery’s type is, send us a photo of its label on WhatsApp and we’ll help identify it.
