KRONOBAT Car Battery

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 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.
