Express 24h delivery. **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [KRONOBAT Batteries](https://baterias.com/gb/kronobat-batteries) - **Canonical URL**: https://baterias.com/gb/car-battery-kronobat - **Language**: en-GB ## Description **KRONOBAT Car batteries**: SLI, EFB and AGM technology for passenger cars, with capacities from 40 to 105 Ah and cold cranking current (CCA) from 360 to 950 A. The best-value car battery range in the Kronobat catalogue, covering everything from cars without Start-Stop to the latest models with regenerative braking. Built for drivers looking for a **cheap car battery** without giving up reliability: from the city runabout to the family SUV, with the exact technology each Start-Stop system requires. ## KRONOBAT Car: SLI, EFB and AGM at the best price The **KRONOBAT Car** range covers the three current passenger-car technologies, each matched to a type of vehicle and starting system: SLI for conventional cars without Start-Stop, EFB for basic Start-Stop, and AGM for Start-Stop with regenerative braking, the highest technical demand. Choosing the right technology matters as much as capacity (Ah): fitting an SLI to a car that requires AGM shortens the battery's life and can disable comfort features. ### KRONOBAT Car technologies and capacities - **SLI** (40-100 Ah, CCA 360-830 A) — non Start-Stop car, the most affordable option. - **EFB** (60-95 Ah, CCA 540-850 A) — basic Start-Stop car. - **AGM** (60-105 Ah, CCA 680-950 A) — Start-Stop car with regenerative braking. ### How to choose your Kronobat car battery Check the spec sheet or the label on your original battery: if it says EFB or AGM, your car needs that specific technology — matching Ah and CCA alone isn't enough. Use the [comparison tool](/gb/comparator) to see at a glance which Kronobat model fits your car by technology, capacity and cranking current. ## Frequently asked questions about Kronobat car batteries ### **How do I know if my car needs SLI, EFB or AGM?** Check the label on the original battery or the vehicle's spec sheet: cars without Start-Stop use SLI, basic Start-Stop cars use EFB, and those that also recover energy under braking need AGM. ### **Can I fit an AGM in a car that had EFB?** Yes, an AGM can always replace an EFB or SLI of the same size, but not the other way round: a car that requires AGM should not run EFB or SLI, as the Start-Stop system may fail or wear the battery out early. ### **What's the price difference between SLI, EFB and AGM?** SLI is the most affordable technology, followed by EFB; AGM costs more due to its higher cycling and energy-recovery demands, though within Kronobat it still keeps a tight value proposition. ### **How long does a Kronobat car battery last?** It depends on use and climate, but all three technologies are built for the starting cycle and typical loads of a passenger car under normal maintenance.
